This LEED Platinum certified house reflects the homeowner's desire for an exceptionally healthy and comfortable living environment, within a traditional neighborhood. INFILL SITE. The family, who moved from another area of Wellesley, sought out this property to be within walking distance of the high school and downtown area. An existing structure on the tight lot was removed to make way for the new home. 84% of the construction waste, from both the previous structure and the new home, was diverted from a landfill. ZED designed to preserve the existing mature trees on the perimeter of the property to minimize site impacts, and to maintain the character of the neighborhood as well as privacy on the site. EXTERIOR EXPRESSION. The street facade of the home relates to the local New England vernacular. The rear uses contemporary language, a nod to the family’s Californian roots, to incorporate a roof deck, solar panels, outdoor living space, and the backyard swimming pool. ZED’s careful planning avoided to the need to face the garage doors towards the street, a common syndrome of a narrow lot. THOUGHTFUL SPACE. Homes with dual entries can often result in duplicate and unused spaces. In this home, the everyday and formal entry areas are one and the same; the front and garage doors share the entry program of coat closets, mudroom storage with bench for removing your shoes, and a laundry room with generous closets for the children's sporting equipment. The entry area leads directly to the living space, encompassing the kitchen, dining and sitting area areas in an L-shaped open plan arrangement. The kitchen is placed at the south-west corner of the space to allow for a strong connection to the dining, sitting and outdoor living spaces. A fire pit on the deck satisfies the family’s desire for an open flame while a sealed gas fireplace is used indoors - ZED’s preference after omitting gas burning appliances completely from an airtight home. A small study, with a window seat, is conveniently located just off of the living space. A first floor guest bedroom includes an accessible bathroom for aging visitors and can be used as a master suite to accommodate aging in place. HEALTHY LIVING. The client requested a home that was easy to clean and would provide a respite from seasonal allergies and common contaminants that are found in many indoor spaces. ZED selected easy to clean solid surface flooring throughout, provided ample space for cleaning supplies on each floor, and designed a mechanical system with ventilation that provides a constant supply of fresh outdoor air. ZED selected durable materials, finishes, cabinetry, and casework with low or no volatile organic compounds (VOCs) and no added urea formaldehyde. YEAR-ROUND COMFORT. The home is super insulated and air-tight, paired with high performance triple-paned windows, to ensure it is draft-free throughout the winter (even when in front of the large windows and doors). ZED designed a right-sized heating and cooling system to pair with the thermally improved building enclosure to ensure year-round comfort. The glazing on the home maximizes passive solar gains, and facilitates cross ventilation and daylighting. ENERGY EFFICIENT. As one of the most energy efficient houses built to date in Wellesley, the home highlights a practical solution for Massachusetts. First, the building enclosure reduces the largest energy requirement for typical houses (heating). Super-insulation, exceptional air sealing, a thermally broken wall assembly, triple pane windows, and passive solar gain combine for a sizable heating load reduction. Second, within the house only efficient systems consume energy. These include an air source heat pump for heating & cooling, a heat pump hot water heater, LED lighting, energy recovery ventilation, and high efficiency appliances. Lastly, photovoltaics provide renewable energy help offset energy consumption. The result is an 89% reduction in energy use compared to a similar brand new home built to code requirements. RESILIENT. The home will fare well in extreme weather events. During a winter power outage, heat loss will be very slow due to the super-insulated and airtight envelope– taking multiple days to drop to 60 degrees even with no heat source. An engineered drainage system, paired with careful the detailing of the foundation, will help to keep the finished basement dry. A generator will provide full operation of the all-electric house during a power outage. OVERALL. The home is a reflection of the family goals and an expression of their values, beautifully enabling health, comfort, safety, resilience, and utility, all while respecting the planet.

Nestled in the lush landscape, a modern reinterpretation of a once-fallen barn now features a charming guest cottage with stylish details and contemporary amenities. Situated along a narrow lot in Germantown, New York, the cottage completes a cluster of existing buildings, forming an intimate courtyard on one side. Steel effect folding patio doors fully open the living areas to the expansive fields and the Catskill Mountains beyond. The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection. Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains. “The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.” A Barn-Inspired Exterior Adds Visual Flair The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond. Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design. “The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.” Interior Design That Mirrors Nature’s Tranquility Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout. Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside. Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline. At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio. Unique Customizations for Visual Appeal and a Steel Effect Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior. In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU. “The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.” Matching Windows and Doors: Create a Cohesive Design Program Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly. “This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.” Sustainability Where It Matters Most New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope. Indoor-Outdoor Living Spaces for Relaxing and Entertaining In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children. Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.” Final Thoughts: A Barn-Inspired Design for Contemporary Living This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons. “When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.” Explore how NanaWall folding patio doors elevate other ADU spaces in our inspiring project photo gallery!

2010 NATIONAL NARI REGIONAL AWARD WINNER Project Scope The owners of this 7,000 square foot colonial in Oakton, Virginia, were seeking a multi-level Mediterranean-style indoor/outdoor living space off the back of their home. They turned to Michael Nash Design, Build & Homes for a design solution that would include a stone patio, a second-story deck, a screened-in porch and linking staircases. While the structure was designed primarily for family dining and entertaining, it also had to accommodate periodic social gatherings of one hundred guests or more. To meet these needs, the project would include a fully-equipped outdoor kitchen, several serving counters with permanent refrigeration, and well-delineated socializing and dining zones. The existing home’s setting offered several impressive assets the new outdoor living area was designed to exploit. The sprawling acreage features old stand trees, wooded paths and a private lake. Beautifully landscaped, it unfolds as an idyllic panorama that naturally draws people to the outdoors. Challenges Since the rear elevation was situated on a slope that drops away from the house, the Michael Nash team had to raise the grade two feet within in a 2,000 square foot area extending out from the back of the house. Infrastructure plans also called for a sophisticated drainage system that had to accommodate a whole series of water “runoff” considerations to be integrated into the decking itself. Excavation included constructing retaining walls to bolster the elevated grade—which also had to support a concrete slab, the primary foundation for the entire complex. Solutions The ground level decking consists of a 2,000 square foot flagstone patio level with the home’s lower level doors. There is a decorative water fountain mid-patio—an ornate collectible acquired in Florida. Food preparation is concentrated within a specially designed semi-circular wall that creates an “outdoor kitchen” equipped with a 60” Viking barbecue grill, a prep sink, a warming drawer, refrigerator and appropriate storage. There is a granite surfaced dining counter with seating for eight. Wrought iron railing and approximately 20 decorative columns (some encasing steel vertical supports) are incorporated into the design scheme. Many of the columns house accent lights. The top level—supported by horizontal steel beams– is a 2,500 square foot deck constructed entirely of Trex decking. The open air decking is, again, directly accessible from rooms on the second level of the house including the kitchen, sunroom and family room. The platform’s most prominent feature is a U-shaped “kitchenette” with cedar shake shingle roofing. Like its counterpart one level below, the facility is equipped with grill, refrigerator and stainless steel cabinetry. One portion of the deck has been allocated for a 16’ x 16’ octagonal screened-in porch crowned by a pair of 2’ x 4’ skylights. The porch can be accessed from the home’s conservatory via a set of French doors. With its mosaic tile flooring, stained cedar panel ceiling and honed granite counters, the interior is elegant and calming. Hand-painted stenciling and a wall-mounted water feature provide distinctive detailing. Finally, the design introduced elements to highlight and reinforce an awareness of the lovely bucolic setting. Fountains and water features combined with textured surfaces and mosaic tiling and backsplashes to present a villa-like ambiance well-suited to the Virginia countryside.

Stuart Wade, Envision Virtual Tours The second-largest and most developed of Georgia's barrier islands, St. Simons is approximately twelve miles long and nearly three miles wide at its widest stretch (roughly the size of Manhattan Island in New York). The island is located in Glynn County on Georgia's coast and lies east of Brunswick (the seat of Glynn County), south of Little St. Simons Island and the Hampton River, and north of Jekyll Island. The resort community of Sea Island is separated from St. Simons on the east by the Black Banks River. Known for its oak tree canopies and historic landmarks, St. Simons is both a tourist destination and, according to the 2010 U.S. census, home to 12,743 residents. Early History The earliest St. Simons Island Village record of human habitation on the island dates to the Late Archaic Period, about 5,000 to 3,000 years ago. Remnants of shell rings left behind by Native Americans from this era survive on many of the barrier islands, including St. Simons. Centuries later, during the period known by historians as the chiefdom era, the Guale Indians established a chiefdom centered on St. Catherines Island and used St. Simons as their hunting and fishing grounds. By 1500 the Guale had established a permanent village of about 200 people on St. Simons, which they called Guadalquini. Beginning in 1568, the Spanish attempted to create missions along the Georgia coast. Catholic missions were the primary means by which Georgia's indigenous Native American chiefdoms were assimilated into the Spanish colonial system along the northern frontier of greater Spanish Florida. In the 1600s St. Simons became home to two Spanish missions: San Buenaventura de Guadalquini, on the southern tip of the island, and Santo Domingo de Asao (or Asajo), on the northern tip. Located on the inland side of the island were the pagan refugee villages of San Simón, the island's namesake, and Ocotonico. In 1684 pirate raids left the missions and villages largely abandoned. Colonial History As Fort Frederica early as 1670, with Great Britain's establishment of the colony of Carolina and its expansion into Georgia territory, Spanish rule was threatened by the English. The Georgia coast was considered "debatable land" by England and Spain, even though Spain had fully retreated from St. Simons by 1702. Thirty-one years later General James Edward Oglethorpe founded the English settlement of Savannah. In 1736 he established Fort Frederica, named after the heir to the British throne, Frederick Louis, prince of Wales, on the west side of St. Simons Island to protect Savannah and the Carolinas from the Spanish threat. Between 1736 and 1749 Fort Frederica was the hub of British military operations along the Georgia frontier. A town of the same name grew up around the fort and was of great importance to the new colony. By 1740 Frederica's population was 1,000. In 1736 the congregation of what would become Christ Church was organized within Fort Frederica as a mission of the Church of England. Charles Wesley led the first services. In 1742 Britain's decisive victory over Spain in the Battle of Bloody Marsh, during the War of Jenkins' Ear, ended the Spanish threat to the Georgia coast. When the British regimen disbanded in 1749, most of the townspeople relocated to the mainland. Fort Frederica went into decline and, except for a short time of prosperity during the 1760s and 1770s under the leadership of merchant James Spalding, never fully recovered. Today the historic citadel's tabby ruins are maintained by the National Park Service. Plantation Era By the start of the American Revolution (1775-83), Fort Frederica was obsolete, and St. Simons was left largely uninhabited as most of its residents joined the patriot army. Besides hosting a small Georgia naval victory on the Fort Frederica River, providing guns from its famous fort for use at Fort Morris in Sunbury, and serving as an arena for pillaging by privateers and British soldiers, the island played almost no role in the war. Following the war, many of the townspeople, their businesses destroyed, turned to agriculture. The island was transformed into fourteen cotton plantations after acres of live oak trees were cleared for farm land and used for building American warships, including the famous USS Constitution, or "Old Ironsides." Although rice was the predominant crop along the neighboring Altamaha River, St. Simons was known for its production of long-staple cotton, which soon came to be known as Sea Island cotton. Between Ebos Landing the 1780s and the outbreak of the Civil War (1861-65), St. Simons's plantation culture flourished. The saline atmosphere and the availability of cheap slave labor proved an ideal combination for the cultivation of Sea Island cotton. In 1803 a group of Ebo slaves who survived the Middle Passage and arrived on the west side of St. Simons staged a rebellion and drowned themselves. The sacred site is known today as Ebos Landing. One of the largest owners of land and slaves on St. Simons was Pierce Butler, master of Hampton Point Plantation, located on the northern end of the island. By 1793 Butler owned more than 500 slaves, who cultivated 800 acres of cotton on St. Simons and 300 acres of rice on Butler's Island in the Altamaha River delta. Butler's grandson, Pierce Mease Butler, who at the age of sixteen inherited a share of his grandfather's estate in 1826, was responsible for the largest sale of human beings in the history of the United States: in 1859, to restore his squandered fortune, he sold 429 slaves in Savannah for more than $300,000. The British actress and writer Fanny Kemble, whose tumultuous marriage to Pierce ended in divorce in 1849, published an eyewitness account of the evils of slavery on St. Simons in her book Journal of a Residence on a Georgian Plantation in 1838-1839 (1863). Another Retreat Plantation large owner of land and slaves on St. Simons was Major William Page, a friend and employee of Pierce Butler Sr. Before purchasing Retreat Plantation on the southwestern tip of the island in 1804, Page managed the Hampton plantation and Butler's Island. Upon Page's death in 1827, Thomas Butler King inherited the land together with his wife, Page's daughter, Anna Matilda Page King. King expanded his father-in-law's planting empire on St. Simons as well as on the mainland, and by 1835 Retreat Plantation alone was home to as many as 355 slaves. The center of life during the island's plantation era was Christ Church, Frederica. Organized in 1807 by a group of island planters, the Episcopal church is the second oldest in the Diocese of Georgia. Embargoes imposed by the War of 1812 (1812-15) prevented the parishioners from building a church structure, so they worshiped in the home of John Beck, which stood on the site of Oglethorpe's only St. Simons residence, Orange Hall. The first Christ Church building, finished on the present site in 1820, was ruined by occupying Union troops during the Civil War. In 1884 the Reverend Anson Dodge Jr. rebuilt the church as a memorial to his first wife, Ellen. The cruciform building with a trussed gothic roof and stained-glass windows remains active today as Christ Church. Civil War and Beyond The St. Simons Island Lighthouse outbreak of the Civil War in 1861 put a sudden end to St. Simons's lucrative plantation era. In January of that year, Confederate troops were stationed at the south end of the island to guard the entrance to Brunswick Harbor. Slaves from Retreat Plantation, owned by Thomas Butler King, built earthworks and batteries. Plantation residents were scattered—the men joined the Confederate army and their families moved to the mainland. Cannon fire was heard on the island in December 1861, and Confederate troops retreated in February 1862, after dynamiting the lighthouse to keep its beacon from aiding Union troops. Soon thereafter, Union troops occupied the island, which was used as a camp for freed slaves. By August 1862 more than 500 former slaves lived on St. Simons, including Susie King Taylor, who organized a school for freed slave children. But in November the ex-slaves were taken to Hilton Head, South Carolina, and Fernandina, Florida, leaving the island abandoned. After the Civil War the island never returned to its status as an agricultural community. The plantations lay dormant because there were no slaves to work the fields. After Union general William T. Sherman's January 1865 Special Field Order No. 15 —a demand that former plantations be divided and distributed to former slaves—was overturned by U.S. president Andrew Johnson less than a year later, freedmen and women were forced to work as sharecroppers on the small farms that dotted the land previously occupied by the sprawling plantations. By St. Simons Lumber Mills 1870 real economic recovery began with the reestablishment of the timber industry. Norman Dodge and Titus G. Meigs of New York set up lumber mill operations at Gascoigne Bluff, formerly Hamilton Plantation. The lumber mills provided welcome employment for both blacks and whites and also provided mail and passenger boats to the mainland. Such water traffic, together with the construction of a new lighthouse in 1872, designed by architect Charles B. Cluskey, marked the beginning of St. Simons's tourism industry. The keeper of the lighthouse created a small amusement park, which drew many visitors, as did the seemingly miraculous light that traveled from the top of the lighthouse tower to the bottom. The island became a summer retreat for families from the mainland, particularly from Baxley, Brunswick, and Waycross. The island's resort industry was thriving by the 1880s. Beachfront structures, such as a new pier and grand hotel, were built on the southeastern end of the island and could be accessed by ferry. Around this time wealthy northerners began vacationing on the island. Twentieth Century The St. Simons Island Pier and Village opening in 1924 of the Brunswick–St. Simons Highway, today known as the Torras Causeway, was a milestone in the development of resorts in the area. St. Simons's beaches were now easily accessible to locals and tourists alike. More than 5,000 automobiles took the short drive from Brunswick to St. Simons via the causeway on its opening day, paving the way for convenient residential and resort development. In 1926 automotive pioneer Howard Coffin of Detroit, Michigan, bought large tracts of land on St. Simons, including the former Retreat Plantation, and constructed a golf course, yacht club, paved roads, and a residential subdivision. Although the causeway had brought large numbers of summer people to the island, St. Simons remained a small community with only a few hundred permanent residents until the 1940s. The St. Simons Island outbreak of World War II (1941-45) brought more visitors and residents to St. Simons. Troops stationed at Jacksonville, Florida; Savannah; and nearby Camp Stewart took weekend vacations on the island, and a new naval air base and radar school became home to even more officers and soldiers. The increased wartime population brought the island its first public school. With a major shipyard for the production of Liberty ships in nearby Brunswick, the waters of St. Simons became active with German U-boats. In April 1942, just off the coast, the Texas Company oil tanker S. S. Oklahoma and the S. S. Esso Baton Rouge were torpedoed by the Germans, bringing the war very close to home for island residents. Due in large part to the military's improvement of the island's infrastructure during the war, development on the island boomed in the 1950s and 1960s. More permanent homes and subdivisions were built, and the island was no longer just a summer resort but also a thriving community. In 1950 the Methodist conference and retreat center Epworth by the Sea opened on Gascoigne Bluff. In 1961 novelist Eugenia Price visited St. Simons and began work on her first works of fiction, known as the St. Simons Trilogy. Inspired by real events on the island, Price's trilogy renewed interest in the history of Georgia's coast, and the novelist herself relocated to the island in 1965 and lived there for thirty-one years. St. Simons is also home to contemporary Georgia writer Tina McElroy Ansa. Since Epworth by the Sea 1980 St. Simons's population has doubled. The island's continued status as a vacation destination and its ongoing development boom have put historic landmarks and natural areas at risk. While such landmarks as the Fort Frederica ruins and the Battle of Bloody Marsh site are preserved and maintained by the National Park Service, and while the historic lighthouse is maintained by the Coastal Georgia Historical Society, historic Ebos Landing has been taken over by a sewage treatment plant. Several coastal organizations have formed in recent years to save natural areas on the island. The St. Simons Land Trust, for example, has received donations of large tracts of land and plans to protect property in the island's three traditional African American neighborhoods. Despite its rapid growth and development, St. Simons remains one of the most beautiful and important islands on the Georgia coast.

2010 NATIONAL NARI REGIONAL AWARD WINNER Project Scope The owners of this 7,000 square foot colonial in Oakton, Virginia, were seeking a multi-level Mediterranean-style indoor/outdoor living space off the back of their home. They turned to Michael Nash Design, Build & Homes for a design solution that would include a stone patio, a second-story deck, a screened-in porch and linking staircases. While the structure was designed primarily for family dining and entertaining, it also had to accommodate periodic social gatherings of one hundred guests or more. To meet these needs, the project would include a fully-equipped outdoor kitchen, several serving counters with permanent refrigeration, and well-delineated socializing and dining zones. The existing home’s setting offered several impressive assets the new outdoor living area was designed to exploit. The sprawling acreage features old stand trees, wooded paths and a private lake. Beautifully landscaped, it unfolds as an idyllic panorama that naturally draws people to the outdoors. Challenges Since the rear elevation was situated on a slope that drops away from the house, the Michael Nash team had to raise the grade two feet within in a 2,000 square foot area extending out from the back of the house. Infrastructure plans also called for a sophisticated drainage system that had to accommodate a whole series of water “runoff” considerations to be integrated into the decking itself. Excavation included constructing retaining walls to bolster the elevated grade—which also had to support a concrete slab, the primary foundation for the entire complex. Solutions The ground level decking consists of a 2,000 square foot flagstone patio level with the home’s lower level doors. There is a decorative water fountain mid-patio—an ornate collectible acquired in Florida. Food preparation is concentrated within a specially designed semi-circular wall that creates an “outdoor kitchen” equipped with a 60” Viking barbecue grill, a prep sink, a warming drawer, refrigerator and appropriate storage. There is a granite surfaced dining counter with seating for eight. Wrought iron railing and approximately 20 decorative columns (some encasing steel vertical supports) are incorporated into the design scheme. Many of the columns house accent lights. The top level—supported by horizontal steel beams– is a 2,500 square foot deck constructed entirely of Trex decking. The open air decking is, again, directly accessible from rooms on the second level of the house including the kitchen, sunroom and family room. The platform’s most prominent feature is a U-shaped “kitchenette” with cedar shake shingle roofing. Like its counterpart one level below, the facility is equipped with grill, refrigerator and stainless steel cabinetry. One portion of the deck has been allocated for a 16’ x 16’ octagonal screened-in porch crowned by a pair of 2’ x 4’ skylights. The porch can be accessed from the home’s conservatory via a set of French doors. With its mosaic tile flooring, stained cedar panel ceiling and honed granite counters, the interior is elegant and calming. Hand-painted stenciling and a wall-mounted water feature provide distinctive detailing. Finally, the design introduced elements to highlight and reinforce an awareness of the lovely bucolic setting. Fountains and water features combined with textured surfaces and mosaic tiling and backsplashes to present a villa-like ambiance well-suited to the Virginia countryside.

Nestled in the lush landscape, a modern reinterpretation of a once-fallen barn now features a charming guest cottage with stylish details and contemporary amenities. Situated along a narrow lot in Germantown, New York, the cottage completes a cluster of existing buildings, forming an intimate courtyard on one side. Steel effect folding patio doors fully open the living areas to the expansive fields and the Catskill Mountains beyond. The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection. Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains. “The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.” A Barn-Inspired Exterior Adds Visual Flair The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond. Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design. “The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.” Interior Design That Mirrors Nature’s Tranquility Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout. Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside. Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline. At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio. Unique Customizations for Visual Appeal and a Steel Effect Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior. In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU. “The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.” Matching Windows and Doors: Create a Cohesive Design Program Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly. “This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.” Sustainability Where It Matters Most New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope. Indoor-Outdoor Living Spaces for Relaxing and Entertaining In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children. Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.” Final Thoughts: A Barn-Inspired Design for Contemporary Living This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons. “When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.” Explore how NanaWall folding patio doors elevate other ADU spaces in our inspiring project photo gallery!

Photography by Natalie Marotta Bungalows are lovable homes, but how can they be better? Along with many of our clients, we find that older (early 20th c.) homes have a lot of character and a comfortable scale, but are leaky, damp (especially in the basement), have fair to poor air quality, and use unconscionable amounts of fossil fuels to heat. The owners of this bungalow were ready to change that, and wanted to do so with minimal upfront carbon emissions as well. The gut renovation included replacing the basement slab and providing capillary breaks and insulation continuously below grade. The brick structure was treated with a fluid-applied air and water barrier from the interior and insulated entirely with cellulose, a carbon-storing insulation. The roof used HFO-blown spray foam to provide sufficient insulation while allowing headroom for bedrooms, bathrooms, and laundry. One great benefit of a full renovation is the possibility of reconfiguring spaces to suit the family’s lifestyle, and to make the best of indoor-outdoor connections. We opened up the main rooms on the first floor, creating a family gathering spot with a view to the back yard, and a spacious kitchen that supports the family’s commitment to cooking for healthy eating. The stair uses a north-facing skylight to bring light from above into the middle of the home, where it was previously dark. As a decarbonization retrofit, the inefficient furnace was replaced with two small ducted heat pump systems, water heating and clothes drying are powered by air-source heat pumps, and cooking uses an induction cooktop plus electric ovens. Energy recovery ventilation provides filtered fresh air continuous exhaust from the kitchen, baths, and laundry, and supplies fresh, highly filtered air to bedrooms and living spaces. The Better Bungalow now makes sense for the 21st century–it now fits the owners’ life-patterns, is super comfortable, has great air quality, and uses a fraction of the energy it did before, greatly lowering the demand on the utility grid. In the near future, when solar PV is installed, it can achieve net zero or near net zero emissions, and with battery backup, can provide great resilience in the event of power outages.

This LEED Platinum certified house reflects the homeowner's desire for an exceptionally healthy and comfortable living environment, within a traditional neighborhood. INFILL SITE. The family, who moved from another area of Wellesley, sought out this property to be within walking distance of the high school and downtown area. An existing structure on the tight lot was removed to make way for the new home. 84% of the construction waste, from both the previous structure and the new home, was diverted from a landfill. ZED designed to preserve the existing mature trees on the perimeter of the property to minimize site impacts, and to maintain the character of the neighborhood as well as privacy on the site. EXTERIOR EXPRESSION. The street facade of the home relates to the local New England vernacular. The rear uses contemporary language, a nod to the family’s Californian roots, to incorporate a roof deck, solar panels, outdoor living space, and the backyard swimming pool. ZED’s careful planning avoided to the need to face the garage doors towards the street, a common syndrome of a narrow lot. THOUGHTFUL SPACE. Homes with dual entries can often result in duplicate and unused spaces. In this home, the everyday and formal entry areas are one and the same; the front and garage doors share the entry program of coat closets, mudroom storage with bench for removing your shoes, and a laundry room with generous closets for the children's sporting equipment. The entry area leads directly to the living space, encompassing the kitchen, dining and sitting area areas in an L-shaped open plan arrangement. The kitchen is placed at the south-west corner of the space to allow for a strong connection to the dining, sitting and outdoor living spaces. A fire pit on the deck satisfies the family’s desire for an open flame while a sealed gas fireplace is used indoors - ZED’s preference after omitting gas burning appliances completely from an airtight home. A small study, with a window seat, is conveniently located just off of the living space. A first floor guest bedroom includes an accessible bathroom for aging visitors and can be used as a master suite to accommodate aging in place. HEALTHY LIVING. The client requested a home that was easy to clean and would provide a respite from seasonal allergies and common contaminants that are found in many indoor spaces. ZED selected easy to clean solid surface flooring throughout, provided ample space for cleaning supplies on each floor, and designed a mechanical system with ventilation that provides a constant supply of fresh outdoor air. ZED selected durable materials, finishes, cabinetry, and casework with low or no volatile organic compounds (VOCs) and no added urea formaldehyde. YEAR-ROUND COMFORT. The home is super insulated and air-tight, paired with high performance triple-paned windows, to ensure it is draft-free throughout the winter (even when in front of the large windows and doors). ZED designed a right-sized heating and cooling system to pair with the thermally improved building enclosure to ensure year-round comfort. The glazing on the home maximizes passive solar gains, and facilitates cross ventilation and daylighting. ENERGY EFFICIENT. As one of the most energy efficient houses built to date in Wellesley, the home highlights a practical solution for Massachusetts. First, the building enclosure reduces the largest energy requirement for typical houses (heating). Super-insulation, exceptional air sealing, a thermally broken wall assembly, triple pane windows, and passive solar gain combine for a sizable heating load reduction. Second, within the house only efficient systems consume energy. These include an air source heat pump for heating & cooling, a heat pump hot water heater, LED lighting, energy recovery ventilation, and high efficiency appliances. Lastly, photovoltaics provide renewable energy help offset energy consumption. The result is an 89% reduction in energy use compared to a similar brand new home built to code requirements. RESILIENT. The home will fare well in extreme weather events. During a winter power outage, heat loss will be very slow due to the super-insulated and airtight envelope– taking multiple days to drop to 60 degrees even with no heat source. An engineered drainage system, paired with careful the detailing of the foundation, will help to keep the finished basement dry. A generator will provide full operation of the all-electric house during a power outage. OVERALL. The home is a reflection of the family goals and an expression of their values, beautifully enabling health, comfort, safety, resilience, and utility, all while respecting the planet.

Nestled in the lush landscape, a modern reinterpretation of a once-fallen barn now features a charming guest cottage with stylish details and contemporary amenities. Situated along a narrow lot in Germantown, New York, the cottage completes a cluster of existing buildings, forming an intimate courtyard on one side. Steel effect folding patio doors fully open the living areas to the expansive fields and the Catskill Mountains beyond. The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection. Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains. “The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.” A Barn-Inspired Exterior Adds Visual Flair The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond. Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design. “The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.” Interior Design That Mirrors Nature’s Tranquility Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout. Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside. Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline. At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio. Unique Customizations for Visual Appeal and a Steel Effect Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior. In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU. “The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.” Matching Windows and Doors: Create a Cohesive Design Program Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly. “This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.” Sustainability Where It Matters Most New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope. Indoor-Outdoor Living Spaces for Relaxing and Entertaining In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children. Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.” Final Thoughts: A Barn-Inspired Design for Contemporary Living This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons. “When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.” Explore how NanaWall folding patio doors elevate other ADU spaces in our inspiring project photo gallery!

This residence was a complete gut renovation of a 4-story row house in Park Slope, and included a new rear extension and penthouse addition. The owners wished to create a warm, family home using a modern language that would act as a clean canvas to feature rich textiles and items from their world travels. As with most Brooklyn row houses, the existing house suffered from a lack of natural light and connection to exterior spaces, an issue that Principal Brendan Coburn is acutely aware of from his experience re-imagining historic structures in the New York area. The resulting architecture is designed around moments featuring natural light and views to the exterior, of both the private garden and the sky, throughout the house, and a stripped-down language of detailing and finishes allows for the concept of the modern-natural to shine. Upon entering the home, the kitchen and dining space draw you in with views beyond through the large glazed opening at the rear of the house. An extension was built to allow for a large sunken living room that provides a family gathering space connected to the kitchen and dining room, but remains distinctly separate, with a strong visual connection to the rear garden. The open sculptural stair tower was designed to function like that of a traditional row house stair, but with a smaller footprint. By extending it up past the original roof level into the new penthouse, the stair becomes an atmospheric shaft for the spaces surrounding the core. All types of weather – sunshine, rain, lightning, can be sensed throughout the home through this unifying vertical environment. The stair space also strives to foster family communication, making open living spaces visible between floors. At the upper-most level, a free-form bench sits suspended over the stair, just by the new roof deck, which provides at-ease entertaining. Oak was used throughout the home as a unifying material element. As one travels upwards within the house, the oak finishes are bleached to further degrees as a nod to how light enters the home. The owners worked with CWB to add their own personality to the project. The meter of a white oak and blackened steel stair screen was designed by the family to read “I love you” in Morse Code, and tile was selected throughout to reference places that hold special significance to the family. To support the owners’ comfort, the architectural design engages passive house technologies to reduce energy use, while increasing air quality within the home – a strategy which aims to respect the environment while providing a refuge from the harsh elements of urban living.

2010 NATIONAL NARI REGIONAL AWARD WINNER Project Scope The owners of this 7,000 square foot colonial in Oakton, Virginia, were seeking a multi-level Mediterranean-style indoor/outdoor living space off the back of their home. They turned to Michael Nash Design, Build & Homes for a design solution that would include a stone patio, a second-story deck, a screened-in porch and linking staircases. While the structure was designed primarily for family dining and entertaining, it also had to accommodate periodic social gatherings of one hundred guests or more. To meet these needs, the project would include a fully-equipped outdoor kitchen, several serving counters with permanent refrigeration, and well-delineated socializing and dining zones. The existing home’s setting offered several impressive assets the new outdoor living area was designed to exploit. The sprawling acreage features old stand trees, wooded paths and a private lake. Beautifully landscaped, it unfolds as an idyllic panorama that naturally draws people to the outdoors. Challenges Since the rear elevation was situated on a slope that drops away from the house, the Michael Nash team had to raise the grade two feet within in a 2,000 square foot area extending out from the back of the house. Infrastructure plans also called for a sophisticated drainage system that had to accommodate a whole series of water “runoff” considerations to be integrated into the decking itself. Excavation included constructing retaining walls to bolster the elevated grade—which also had to support a concrete slab, the primary foundation for the entire complex. Solutions The ground level decking consists of a 2,000 square foot flagstone patio level with the home’s lower level doors. There is a decorative water fountain mid-patio—an ornate collectible acquired in Florida. Food preparation is concentrated within a specially designed semi-circular wall that creates an “outdoor kitchen” equipped with a 60” Viking barbecue grill, a prep sink, a warming drawer, refrigerator and appropriate storage. There is a granite surfaced dining counter with seating for eight. Wrought iron railing and approximately 20 decorative columns (some encasing steel vertical supports) are incorporated into the design scheme. Many of the columns house accent lights. The top level—supported by horizontal steel beams– is a 2,500 square foot deck constructed entirely of Trex decking. The open air decking is, again, directly accessible from rooms on the second level of the house including the kitchen, sunroom and family room. The platform’s most prominent feature is a U-shaped “kitchenette” with cedar shake shingle roofing. Like its counterpart one level below, the facility is equipped with grill, refrigerator and stainless steel cabinetry. One portion of the deck has been allocated for a 16’ x 16’ octagonal screened-in porch crowned by a pair of 2’ x 4’ skylights. The porch can be accessed from the home’s conservatory via a set of French doors. With its mosaic tile flooring, stained cedar panel ceiling and honed granite counters, the interior is elegant and calming. Hand-painted stenciling and a wall-mounted water feature provide distinctive detailing. Finally, the design introduced elements to highlight and reinforce an awareness of the lovely bucolic setting. Fountains and water features combined with textured surfaces and mosaic tiling and backsplashes to present a villa-like ambiance well-suited to the Virginia countryside.
