Klopf Architecture, Outer Space Landscape Architects, Sezen & Moon Structural Engineer and Flegels Construction updated a classic Eichler open, indoor-outdoor home. Everyone loved the classic, original bones of this house, but it was in need of a major facelift both inside and out. The owners also wanted to remove the barriers between the kitchen and great room, and increase the size of the master bathroom as well as make other layout changes. No addition to the house was contemplated. The owners worked with Klopf Architecture in part because of Klopf’s extensive mid-century modern / Eichler design portfolio, and in part because one of their neighbors who had worked with Klopf on their Eichler home remodel referred them. The Klopf team knew how to update the worn finishes to make a more sophisticated, higher quality home that both looks better and functions better. In conjunction with the atrium and the landscaped rear yard / patio, the glassy living room feels open on both sides and allows an indoor / outdoor flow throughout. The new, natural wood exterior siding runs through the house from inside to outside to inside again, updating one of the classic design features of the Eichler homes. Picking up on the wood siding, walnut vanities and cabinets offset the white walls. Gray porcelain tiles evoke the concrete slab floors and flow from interior to exterior to make the spaces appear to flow together. Similarly the ceiling decking has the same white-washed finish from inside to out. The continuity of materials and space enhances the sense of flow. The large kitchen, perfect for entertaining, has a wall of built-ins and an oversized island. There’s plenty of storage and space for the whole group to prep and cook together. One unique approach to the master bedroom is the bed wall. The head of the bed is tucked within a line of built-in wardrobes with a high window above. Replacing the master closet with this wall of wardrobes allowed for both a larger bathroom and a larger bedroom. This 1,953 square foot, 4 bedroom, 2 bathroom Double Gable Eichler remodeled single-family house is located in Mountain View in the heart of the Silicon Valley.

Well-traveled. Relaxed. Timeless. Our well-traveled clients were soon-to-be empty nesters when they approached us for help reimagining their Presidio Heights home. The expansive Spanish-Revival residence originally constructed in 1908 had been substantially renovated 8 year prior, but needed some adaptations to better suit the needs of a family with three college-bound teens. We evolved the space to be a bright, relaxed reflection of the family’s time together, revising the function and layout of the ground-floor rooms and filling them with casual, comfortable furnishings and artifacts collected abroad. One of the key changes we made to the space plan was to eliminate the formal dining room and transform an area off the kitchen into a casual gathering spot for our clients and their children. The expandable table and coffee/wine bar means the room can handle large dinner parties and small study sessions with similar ease. The family room was relocated from a lower level to be more central part of the main floor, encouraging more quality family time, and freeing up space for a spacious home gym. In the living room, lounge-worthy upholstery grounds the space, encouraging a relaxed and effortless West Coast vibe. Exposed wood beams recall the original Spanish-influence, but feel updated and fresh in a light wood stain. Throughout the entry and main floor, found artifacts punctate the softer textures — ceramics from New Mexico, religious sculpture from Asia and a quirky wall-mounted phone that belonged to our client’s grandmother.

Klopf Architecture and Outer space Landscape Architects designed a new warm, modern, open, indoor-outdoor home in Los Altos, California. Inspired by mid-century modern homes but looking for something completely new and custom, the owners, a couple with two children, bought an older ranch style home with the intention of replacing it. Created on a grid, the house is designed to be at rest with differentiated spaces for activities; living, playing, cooking, dining and a piano space. The low-sloping gable roof over the great room brings a grand feeling to the space. The clerestory windows at the high sloping roof make the grand space light and airy. Upon entering the house, an open atrium entry in the middle of the house provides light and nature to the great room. The Heath tile wall at the back of the atrium blocks direct view of the rear yard from the entry door for privacy. The bedrooms, bathrooms, play room and the sitting room are under flat wing-like roofs that balance on either side of the low sloping gable roof of the main space. Large sliding glass panels and pocketing glass doors foster openness to the front and back yards. In the front there is a fenced-in play space connected to the play room, creating an indoor-outdoor play space that could change in use over the years. The play room can also be closed off from the great room with a large pocketing door. In the rear, everything opens up to a deck overlooking a pool where the family can come together outdoors. Wood siding travels from exterior to interior, accentuating the indoor-outdoor nature of the house. Where the exterior siding doesn’t come inside, a palette of white oak floors, white walls, walnut cabinetry, and dark window frames ties all the spaces together to create a uniform feeling and flow throughout the house. The custom cabinetry matches the minimal joinery of the rest of the house, a trim-less, minimal appearance. Wood siding was mitered in the corners, including where siding meets the interior drywall. Wall materials were held up off the floor with a minimal reveal. This tight detailing gives a sense of cleanliness to the house. The garage door of the house is completely flush and of the same material as the garage wall, de-emphasizing the garage door and making the street presentation of the house kinder to the neighborhood. The house is akin to a custom, modern-day Eichler home in many ways. Inspired by mid-century modern homes with today’s materials, approaches, standards, and technologies. The goals were to create an indoor-outdoor home that was energy-efficient, light and flexible for young children to grow.

Overview Extension and complete refurbishment. The Brief The existing house had very shallow rooms with a need for more depth throughout the property by extending into the rear garden which is large and south facing. We were to look at extending to the rear and to the end of the property, where we had redundant garden space, to maximise the footprint and yield a series of WOW factor spaces maximising the value of the house. The brief requested 4 bedrooms plus a luxurious guest space with separate access; large, open plan living spaces with large kitchen/entertaining area, utility and larder; family bathroom space and a high specification ensuite to two bedrooms. In addition, we were to create balconies overlooking a beautiful garden and design a ‘kerb appeal’ frontage facing the sought-after street location. Buildings of this age lend themselves to use of natural materials like handmade tiles, good quality bricks and external insulation/render systems with timber windows. We specified high quality materials to achieve a highly desirable look which has become a hit on Houzz. Our Solution One of our specialisms is the refurbishment and extension of detached 1930’s properties. Taking the existing small rooms and lack of relationship to a large garden we added a double height rear extension to both ends of the plan and a new garage annex with guest suite. We wanted to create a view of, and route to the garden from the front door and a series of living spaces to meet our client’s needs. The front of the building needed a fresh approach to the ordinary palette of materials and we re-glazed throughout working closely with a great build team.

The beautiful, old barn on this Topsfield estate was at risk of being demolished. Before approaching Mathew Cummings, the homeowner had met with several architects about the structure, and they had all told her that it needed to be torn down. Thankfully, for the sake of the barn and the owner, Cummings Architects has a long and distinguished history of preserving some of the oldest timber framed homes and barns in the U.S. Once the homeowner realized that the barn was not only salvageable, but could be transformed into a new living space that was as utilitarian as it was stunning, the design ideas began flowing fast. In the end, the design came together in a way that met all the family’s needs with all the warmth and style you’d expect in such a venerable, old building. On the ground level of this 200-year old structure, a garage offers ample room for three cars, including one loaded up with kids and groceries. Just off the garage is the mudroom – a large but quaint space with an exposed wood ceiling, custom-built seat with period detailing, and a powder room. The vanity in the powder room features a vanity that was built using salvaged wood and reclaimed bluestone sourced right on the property. Original, exposed timbers frame an expansive, two-story family room that leads, through classic French doors, to a new deck adjacent to the large, open backyard. On the second floor, salvaged barn doors lead to the master suite which features a bright bedroom and bath as well as a custom walk-in closet with his and hers areas separated by a black walnut island. In the master bath, hand-beaded boards surround a claw-foot tub, the perfect place to relax after a long day. In addition, the newly restored and renovated barn features a mid-level exercise studio and a children’s playroom that connects to the main house. From a derelict relic that was slated for demolition to a warmly inviting and beautifully utilitarian living space, this barn has undergone an almost magical transformation to become a beautiful addition and asset to this stately home.

The comfortable elegance of this French-Country inspired home belies the challenges faced during its conception. The beautiful, wooded site was steeply sloped requiring study of the location, grading, approach, yard and views from and to the rolling Pennsylvania countryside. The client desired an old world look and feel, requiring a sensitive approach to the extensive program. Large, modern spaces could not add bulk to the interior or exterior. Furthermore, it was critical to balance voluminous spaces designed for entertainment with more intimate settings for daily living while maintaining harmonic flow throughout. The result home is wide, approached by a winding drive terminating at a prominent facade embracing the motor court. Stone walls feather grade to the front façade, beginning the masonry theme dressing the structure. A second theme of true Pennsylvania timber-framing is also introduced on the exterior and is subsequently revealed in the formal Great and Dining rooms. Timber-framing adds drama, scales down volume, and adds the warmth of natural hand-wrought materials. The Great Room is literal and figurative center of this master down home, separating casual living areas from the elaborate master suite. The lower level accommodates casual entertaining and an office suite with compelling views. The rear yard, cut from the hillside, is a composition of natural and architectural elements with timber framed porches and terraces accessed from nearly every interior space flowing to a hillside of boulders and waterfalls. The result is a naturally set, livable, truly harmonious, new home radiating old world elegance. This home is powered by a geothermal heating and cooling system and state of the art electronic controls and monitoring systems. The roof is simulated slate made from recycled materials.

View Haus 5 is an innovative approach to infill development on a narrow site. All homes were designed to Passivhaus standards and one of them has been certified. In response to the site's topography the townhouses are terraced in a single structure. A common walkway connects the site from 25th Avenue E to the alley widening at the center of the site to form a common courtyard. The courtyard is terraced to separate home entries in section from the surface of the courtyard. Decks created to be similar to front porches border the courtyard along with thoughtful landscaping. The massing is modulated to create a structure that is well-scaled to its surroundings. Parking is minimized on the site through its location at the rear alley and setting it below the structure. To minimize impact on adjacent sites, a single enclosed stair penthouse is located at the center of the site, integrated with the design's approach to interlocking masses of varying materials. The exterior materials includes reclaimed brick and wood, ebonized wood and painted cement board panels.

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!

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!

View Haus 5 is an innovative approach to infill development on a narrow site. All homes were designed to Passivhaus standards and one of them has been certified. In response to the site's topography the townhouses are terraced in a single structure. A common walkway connects the site from 25th Avenue E to the alley widening at the center of the site to form a common courtyard. The courtyard is terraced to separate home entries in section from the surface of the courtyard. Decks created to be similar to front porches border the courtyard along with thoughtful landscaping. The massing is modulated to create a structure that is well-scaled to its surroundings. Parking is minimized on the site through its location at the rear alley and setting it below the structure. To minimize impact on adjacent sites, a single enclosed stair penthouse is located at the center of the site, integrated with the design's approach to interlocking masses of varying materials. The exterior materials includes reclaimed brick and wood, ebonized wood and painted cement board panels.

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.
