Plantique, INC http://www.plantique.com Entry Name: Classic Fireside Getaway 2014 PLNA Awards for Landscape Excellence Winner Category: Hardscaping-Residential $30,000-$60,000 Award Level: Bronze Photo Description: The initial call from these homeowners was about a drainage issue. After having installed new roofing, siding, and a new porch enclosure, it was discovered that the original piping for the downspouts had failed. A few recent rainstorms had left a large pool of water behind the house. The new gutters and downspouts were now properly channeling water into a sub-surface piping system that no longer functioned. Obviously this had to be fixed, but after some further discussions, it was suggested that if a cost-effective solution could be found, perhaps a patio could be created along with the drainage solution. This would make the space between the porch and the pool more useful. The surfaces would have to be as kid-friendly as possible, as the homeowners foresaw frequent visits by their grandchildren. The flow of the spaces would have to be such that small bikes would be able to easily maneuver around chairs and tables. After a site study was conducted, several issues were discovered. Pertaining to the drainage issue, it was determined that the grade sloped directly toward the porch from the pool. This not only channeled water toward the house and porch, but created a dam in an already shallow drainage swale that trapped water off to the side of the porch. Since the soil in this area is predominantly clay, water could sit in that area for days until it drained away. On the aesthetic side, a good part of the house’s façade was brick, the porch floor was brick, the small patio and walkways were brick, and the seating wall next to the pool was brick; there was a lot of brick. The challenge would be to find a cost-effective material that would contrast will with the brick, while creating a functional patio space that also facilitated water drainage. The solution involved a significant re-grading of the area between the pool and the house, along with the installation of a completely new drain system to channel roof water away from the area. Working with the fixed points of the porch and foundation levels of the home, the slope that pitched toward the house was cut into to create a positive pitch away from the house. This created 20 in. high cut at the furthest point from the porch. To retain this, a segmental retaining wall block was used to form a curved seating wall around a mortared brick fire ring, perfect for evening campfires and marshmallow roasting with the grandchildren. Prior to the patio construction, new subsurface PVC piping was installed to channel water away from the house, under the patio, and to daylight about 100 ft. further into the side yard where it could properly drain. To construct the patio, the existing dry laid brick walks and patio were recycled as a border around a gray colored concrete paver that mimics the look of more expensive PA Bluestone, an often used companion to brick. The smooth surface texture and tight joint provide a barefoot friendly walking surface that stays cooler in the hot summer sun. The patio itself is also pitched so as to drain runoff to the lower end of the yard in case of a failure in the drain piping. Along with providing several clear pathways between the porch, pool, and driveway the new patio includes an open air dining area, a fire pit area, and a seating/lounging area (not yet furnished at the time of the photo) for larger family gatherings or more intimate dinners and fire-side relaxation.

transFORM had the honor of designing, manufacturing and installing a crisp new walk-in closet at The Chatsworth - a historic Beaux Art building located in the heart of Manhattan's charming Upper West Side. Built in 1904, The Chatsworth was reintroduced in 2015 with expanded floor plans, incredible amenities and a private club-like atmosphere. transFORM’s Senior Design Manager Rozalia Kiss, worked with the HFZ Capital Group to create a striking bedroom sized walk-in closet, which was recently featured in the New York Times article : Closets as Big as Some Apartments. The article identifies spacious closets as the latest must-have in some of the city’s most expensive condominiums. Quickly becoming an essential part of the modern home, a walk-in closet adds style and convenience to your daily routine. Designed in a clean white finish and tastefully accented with complementing polished chrome hardware, this custom walk-in closet delivers tons of functional and accessible space. All-white cabinetry offers a crisp look that allows your clothing to steal the spotlight. The high-contrast shaker style doors, create an elegant backdrop for your clothing. Light also pours through the big windows, drawing your eye to the iconic views of the Hudson River. It creates a feeling of brightness and positivity that energizes and enlivens. It’s a walk-in closet where you can look and feel your best as you begin your day. For added visual appeal, the unit was accented with crown and base molding. The elegant detailing was inspired by the pre-war era building’s architectural features. The moldings add a retro geometric touch that matches the apartments beamed ceilings and traditional herringbone floors that were all the rage during the period and make a striking comeback in this beautiful renovation. This unit was specifically designed with a variety of open shelves, hanging sections, and shoe storage. Hanging sections provide enough elevation to conveniently organize items based on size. From blazers and blouses to maxi skirts and evening gowns, all of your clothing is easily accessible. By using the same color hangers, your space will appear even more collected and composed. You can also arrange your clothing so that the colors compliment each other and appear as the favorable options they really are. For the shoe enthusiast, we included numerous sets of shoe shelves and cubbies that attractively organize and showcase your finest footwear. This type of system allows you to identify and grab your favorite pair as you mix and match the perfect ensemble. Shelving provides many of the same storage functions as drawers or baskets, but at a more economical price point. Items on open shelves are easier to recognize as a match for an outfit than items inside drawers. Top shelves are best for large, lightweight and seldomly-used items like your favorite floppy beach hat. Middle shelves, which tend to be the units focal point can be personalized with photos and home decor. Bottom shelves provide easy access to your most frequently used items like cozy sweaters and beloved slacks. This custom closet also includes three tilt-out laundry hampers. No more dragging big clunky laundry baskets around the house. Tilt-out hampers are removable, lightweight nylon bags and easy to grab and go. They are stored behind cabinet faces that blend in with your space, removing unsightly and unpleasant-to-be-around dirty laundry from accumulating in piles on the floor. Installing 2 - 3 tilt-outs will make sorting laundry lightning fast. These hampers help keep your closet clean and tidy and increase space without losing functionality. Let's face it, an organized custom closet just looks great. The side benefit is increased awareness and more pride in your clothing and your day-to-day appearance. With an organized system everything has its place and you can find the garments you need in the moment you need them, sans the ‘what to wear’ frustration.

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!

The Harmonious Blending of Inside to Out with Wood Framed Patio Doors By NanaWall Systems, September 3, 2025 Wood framed patio doors Some homes are designed to impress from the outside. This one was reimagined to breathe from the inside out with wood framed patio doors. For a family of music lovers and outdoor enthusiasts, the goal was about connection. Connection to each other, to the seasons, to nature, to sound, and to their lush backyard space for daily life and family gatherings. Designed by Jason Hanrahan of Mode Architects, the home features a thoughtfully placed NanaWall kitchen pass-through window and, later, wide bifold doors in the family sunroom. The design evolved in two phases to fit the family’s indoor-outdoor lifestyle perfectly. The result is a renovation defined by openness, light, and laid-back living. A Home Shaped by Light, Music, Wood Framed Patio Doors, and a Pass-Through Window Kitchen Renovation Opens Space to Light and Entertaining with a Pass-Through Window During phase one of the renovation, the existing kitchen was reimagined to replace a restrictive floor plan and outdated appliances. Central to its new design is a three-panel NanaWall SL60 folding window system—sized at counter height to serve as a flexible pass-through window for alfresco dining and entertaining. Custom divided lites were added to complement the home’s existing window styles. The window frames were finished in a warm, off-white on both interior and exterior, tying the kitchen seamlessly to the rest of the home and its façade. The result is a transitional space that connects the kitchen directly to the outdoor dining area, a seamless connection across spaces. “The countertop-height NanaWall system made the kitchen fit better into the family’s lifestyle,” says Hanrahan. “It supports hosting and day-to-day use without turning the kitchen into a full opening.” Designed for Living: Home Reimagined Around How the Family Connects After phase one introduced a NanaWall pass-through window in the kitchen, making serving, conversation, and time outside effortless, the homeowners returned to MODE to reimagine their older sunroom. The goal: a living room and music lounge that could open completely to the backyard. The solution was incorporating a full-height, five-panel NW Clad 740 wood framed patio doors. The Generation 4 folding glass wall offered the slimmest aluminum clad frames available, and therefore, was the ideal solution to achieve seamless connectivity. Outside, the frames were finished in a warm off-white to match the façade. Inside, solid wood frames seamlessly integrate with the mushroom wood paneling and millwork. The nearly 15-foot-wide system was customized with divided lites placed high up to add rhythm while preserving unobstructed views and keeping transitions seamless. “We wanted to maximize the opening size,” says Jason. “Not just to maximize light, but literally the opening as well. The family sunroom space became more useful.” A Living Sunroom That Folds Open to the Garden MODE centered the second half of the home renovation on the family sunroom, featuring wood framed patio doors to create a seamless transition from the interior to the garden. It’s the difference between “a room with a view” and a room that becomes the view. With the nearly 8-foot-tall system open, music spills outside; with it closed, daylight, acoustics, and comfort remain finely tuned. “You are sitting in the house with the family. The opening frames the view of the pond and the trees,” describes Architect Jason Hanrahan. “They liked how it connected them with their family when they were outside… it made it more cohesive.” Choosing Materials that Reflect Nature and Serenity According to the architect, the design aims to bring the outdoors in with an organic material approach. Inside, the room is wrapped in mushroom wood reclaimed boards, whose textured grain warms the acoustics and steadies the eye. Large-format tiles keep lines calm and maintenance easy. Outside, a long concrete tread and natural stone hold the grade without hard edges. Nothing shouts; everything contributes to a single idea: bring the outdoors in and the indoors out. Energy Efficiency Meets Everyday Living The systems’ energy-efficient and performance engineering make the sunroom a four-season retreat. The architect chose NanaWall wood framed patio doors to maximize the existing exterior opening, provide intuitive and easy daily operation, and create a threshold that feels like part of the floor rather than a barrier. T hese are hallmarks of NanaWall wood framed patio doors: engineered for durability and frequent use, precision-gliding panels, and performance-tested. To ensure year-round comfort, the NanaWall wood framed patio doors and pass-through window were specified with double glazed panels for optimal performance regardless of weather. Paired with the thermally broken Low Profile Saddle Sill, the bifold door not only offers energy efficiency but also a seamless, barefoot-friendly threshold to the outdoors. Final Thoughts From weeknight dinners to weekend music sessions, this is now a home that meets the family at the place they actually live, gather, and connect in. The kitchen pass-through window keeps everyday hosting effortless. The music room turns into a garden room in seconds, inviting breezes and conversation across one continuous plane. Here, NanaWall wood framed patio doors added versatile usable square footage and extended the soul of the home outdoors. By focusing on how the family truly lives, this home now opens in all the right ways: to light, to laughter, to nature, and to each other.

This long-time family home was ready for a thoughtful evolution. Originally built years ago, the homeowners came to us seeking a comprehensive renovation that better reflected how they live today — entertaining frequently, welcoming their grown children home for holidays and summers, and desiring spaces that feel elevated, functional, and deeply personal. What began as a kitchen and bath update ultimately became a whole-home transformation, touching every floor — from the main living level to the bedroom floor and even the attic. On the first floor, we completed a full gut renovation and thoughtful reconfiguration of the layout. Walls were removed — including a former pantry and powder room — to dramatically improve sightlines and flow between the kitchen and living room. The kitchen footprint was expanded to accommodate a generously sized island designed for gathering. A two-tone cabinetry palette establishes subtle zoning: Farrow & Ball Stiffkey Blue anchors the island and refrigerator surround, while White Tie brightens the perimeter cabinetry. Paneled appliances conceal the dishwasher and trash, while a stainless refrigerator adds balance and contrast. Antique brass hardware and oversized statement pendants layer in warmth and charm. Inside the cabinetry, custom storage solutions — from built-in spice racks and pull-out trays to a dedicated Tupperware drawer with lid dividers — ensure everything has its place. The former dining room was reimagined as a full-service butler’s pantry, complete with a second prep sink, paneled beverage drawers, an ice maker, glass display cabinetry, and abundant storage. Two built-in desks and a bench create a flexible zone for puzzles, homework, or casual seating. By relocating coffee and cocktail service to this dedicated space, the main kitchen remains uncluttered — even during large gatherings. The powder room was thoughtfully relocated to support the new layout and transformed into a jewel-box moment for guests. Schumacher’s Romantic Bosphorus mural wallpaper creates a hand-painted, immersive experience. A custom console vanity with a Carrara marble top and backsplash pairs beautifully with an antique brass wall-mounted faucet, layered with warm lighting and brass finishes for an unforgettable impression. Beyond the kitchen, we opened up the living room and installed a custom bi-fold door system that seamlessly connects the interior to the screened-in porch, enhancing indoor-outdoor living. A bespoke music room was also created on the main level, complete with integrated soundproofing and custom cabinetry designed to house instruments, sheet music, a piano, and a concealed sound system — allowing the family’s love of music to be fully supported without visual clutter. Throughout the home, existing hardwood floors were refinished, and new decorative lighting and upgraded recessed lighting were installed to elevate both ambiance and functionality. On the bedroom floor, every space received a refresh. Each bedroom was thoughtfully updated with custom wallpaper and wall coverings, while the shared bathroom was fully renovated to incorporate a highly functional laundry area. Durable finishes, smart storage solutions, and a clean layout ensure it works seamlessly for adult children when home while still serving daily needs year-round. The primary bathroom was transformed into a serene retreat designed for daily restoration. A soft neutral palette and layered materials create a calming environment, while half of the space functions as a wet room where the tub and shower share one expansive area. Porcelain tile with a Calacatta marble look delivers timeless elegance without the maintenance of natural stone. Champagne Bronze fixtures complement natural cherry cabinetry — a nod to the homeowner’s passion for woodworking — and thoughtful recessed niches provide clean, hidden storage. Even the attic was elevated to support modern living. Previously underutilized, the space was upgraded to serve as a dedicated home office for the homeowner, who works there daily. Improved lighting, finishes, and function transformed it into a productive and comfortable retreat tucked away from the main living areas. Integrated technology plays a key role throughout the home. A Control4 smart home automation system was implemented to seamlessly manage sound, lighting, and comfort. Custom blinds, drapery, and upholstery were carefully coordinated and fabricated to complement each space, adding softness and cohesion from room to room. This project represents more than a renovation — it is a full reimagining of how the home supports gathering, creativity, comfort, and daily life. Every floor was thoughtfully considered. Every space was elevated. And the result is a sophisticated yet welcoming home designed to serve this family beautifully for years to come.

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!

transFORM had the honor of designing, manufacturing and installing a crisp new walk-in closet at The Chatsworth - a historic Beaux Art building located in the heart of Manhattan's charming Upper West Side. Built in 1904, The Chatsworth was reintroduced in 2015 with expanded floor plans, incredible amenities and a private club-like atmosphere. transFORM’s Senior Design Manager Rozalia Kiss, worked with the HFZ Capital Group to create a striking bedroom sized walk-in closet, which was recently featured in the New York Times article : Closets as Big as Some Apartments. The article identifies spacious closets as the latest must-have in some of the city’s most expensive condominiums. Quickly becoming an essential part of the modern home, a walk-in closet adds style and convenience to your daily routine. Designed in a clean white finish and tastefully accented with complementing polished chrome hardware, this custom walk-in closet delivers tons of functional and accessible space. All-white cabinetry offers a crisp look that allows your clothing to steal the spotlight. The high-contrast shaker style doors, create an elegant backdrop for your clothing. Light also pours through the big windows, drawing your eye to the iconic views of the Hudson River. It creates a feeling of brightness and positivity that energizes and enlivens. It’s a walk-in closet where you can look and feel your best as you begin your day. For added visual appeal, the unit was accented with crown and base molding. The elegant detailing was inspired by the pre-war era building’s architectural features. The moldings add a retro geometric touch that matches the apartments beamed ceilings and traditional herringbone floors that were all the rage during the period and make a striking comeback in this beautiful renovation. This unit was specifically designed with a variety of open shelves, hanging sections, and shoe storage. Hanging sections provide enough elevation to conveniently organize items based on size. From blazers and blouses to maxi skirts and evening gowns, all of your clothing is easily accessible. By using the same color hangers, your space will appear even more collected and composed. You can also arrange your clothing so that the colors compliment each other and appear as the favorable options they really are. For the shoe enthusiast, we included numerous sets of shoe shelves and cubbies that attractively organize and showcase your finest footwear. This type of system allows you to identify and grab your favorite pair as you mix and match the perfect ensemble. Shelving provides many of the same storage functions as drawers or baskets, but at a more economical price point. Items on open shelves are easier to recognize as a match for an outfit than items inside drawers. Top shelves are best for large, lightweight and seldomly-used items like your favorite floppy beach hat. Middle shelves, which tend to be the units focal point can be personalized with photos and home decor. Bottom shelves provide easy access to your most frequently used items like cozy sweaters and beloved slacks. This custom closet also includes three tilt-out laundry hampers. No more dragging big clunky laundry baskets around the house. Tilt-out hampers are removable, lightweight nylon bags and easy to grab and go. They are stored behind cabinet faces that blend in with your space, removing unsightly and unpleasant-to-be-around dirty laundry from accumulating in piles on the floor. Installing 2 - 3 tilt-outs will make sorting laundry lightning fast. These hampers help keep your closet clean and tidy and increase space without losing functionality. Let's face it, an organized custom closet just looks great. The side benefit is increased awareness and more pride in your clothing and your day-to-day appearance. With an organized system everything has its place and you can find the garments you need in the moment you need them, sans the ‘what to wear’ frustration.

This long-time family home was ready for a thoughtful evolution. Originally built years ago, the homeowners came to us seeking a comprehensive renovation that better reflected how they live today — entertaining frequently, welcoming their grown children home for holidays and summers, and desiring spaces that feel elevated, functional, and deeply personal. What began as a kitchen and bath update ultimately became a whole-home transformation, touching every floor — from the main living level to the bedroom floor and even the attic. On the first floor, we completed a full gut renovation and thoughtful reconfiguration of the layout.

  Free ebook, Creating the Ideal Kitchen. DOWNLOAD NOW   The Klimala’s and their three kids are no strangers to moving, this being their fifth house in the same town over the 20-year period they have lived there. “It must be the 7-year itch, because every seven years, we seem to find ourselves antsy for a new project or a new environment. I think part of it is being a designer, I see my own taste evolve and I want my environment to reflect that. Having easy access to wonderful tradesmen and a knowledge of the process makes it that much easier”. This time, Klimala’s fell in love with a somewhat unlikely candidate. The 1950’s ranch turned cape cod was a bit of a mutt, but it’s location 5 minutes from their design studio and backing up to the high school where their kids can roll out of bed and walk to school, coupled with the charm of its location on a private road and lush landscaping made it an appealing choice for them. “The bones of the house were really charming. It was typical 1,500 square foot ranch that at some point someone added a second floor to. Its sloped roofline and dormered bedrooms gave it some charm.” With the help of architect Maureen McHugh, Klimala’s gutted and reworked the layout to make the house work for them. An open concept kitchen and dining room allows for more frequent casual family dinners and dinner parties that linger. A dingy 3-season room off the back of the original house was insulated, given a vaulted ceiling with skylights and now opens up to the kitchen. This room now houses an 8’ raw edge white oak dining table and functions as an informal dining room. “One of the challenges with these mid-century homes is the 8’ ceilings. I had to have at least one room that had a higher ceiling so that’s how we did it” states Klimala. The kitchen features a 10’ island which houses a 5’0” Galley Sink. The Galley features two faucets, and double tiered rail system to which accessories such as cutting boards and stainless steel bowls can be added for ease of cooking. Across from the large sink is an induction cooktop. “My two teen daughters and I enjoy cooking, and the Galley and induction cooktop make it so easy.” A wall of tall cabinets features a full size refrigerator, freezer, double oven and built in coffeemaker. The area on the opposite end of the kitchen features a pantry with mirrored glass doors and a beverage center below. The rest of the first floor features an entry way, a living room with views to the front yard’s lush landscaping, a family room where the family hangs out to watch TV, a back entry from the garage with a laundry room and mudroom area, one of the home’s four bedrooms and a full bath. There is a double sided fireplace between the family room and living room. The home features pops of color from the living room’s peach grass cloth to purple painted wall in the family room. “I’m definitely a traditionalist at heart but because of the home’s Midcentury roots, I wanted to incorporate some of those elements into the furniture, lighting and accessories which also ended up being really fun. We are not formal people so I wanted a house that my kids would enjoy, have their friends over and feel comfortable.” The second floor houses the master bedroom suite, two of the kids’ bedrooms and a back room nicknamed “the library” because it has turned into a quiet get away area where the girls can study or take a break from the rest of the family. The area was originally unfinished attic, and because the home was short on closet space, this Jack and Jill area off the girls’ bedrooms houses two large walk-in closets and a small sitting area with a makeup vanity. “The girls really wanted to keep the exposed brick of the fireplace that runs up the through the space, so that’s what we did, and I think they feel like they are in their own little loft space in the city when they are up there” says Klimala.

This long-time family home was ready for a thoughtful evolution. Originally built years ago, the homeowners came to us seeking a comprehensive renovation that better reflected how they live today — entertaining frequently, welcoming their grown children home for holidays and summers, and desiring spaces that feel elevated, functional, and deeply personal. What began as a kitchen and bath update ultimately became a whole-home transformation, touching every floor — from the main living level to the bedroom floor and even the attic. On the first floor, we completed a full gut renovation and thoughtful reconfiguration of the layout. Walls were removed — including a former pantry and powder room — to dramatically improve sightlines and flow between the kitchen and living room. The kitchen footprint was expanded to accommodate a generously sized island designed for gathering. A two-tone cabinetry palette establishes subtle zoning: Farrow & Ball Stiffkey Blue anchors the island and refrigerator surround, while White Tie brightens the perimeter cabinetry. Paneled appliances conceal the dishwasher and trash, while a stainless refrigerator adds balance and contrast. Antique brass hardware and oversized statement pendants layer in warmth and charm. Inside the cabinetry, custom storage solutions — from built-in spice racks and pull-out trays to a dedicated Tupperware drawer with lid dividers — ensure everything has its place. The former dining room was reimagined as a full-service butler’s pantry, complete with a second prep sink, paneled beverage drawers, an ice maker, glass display cabinetry, and abundant storage. Two built-in desks and a bench create a flexible zone for puzzles, homework, or casual seating. By relocating coffee and cocktail service to this dedicated space, the main kitchen remains uncluttered — even during large gatherings. The powder room was thoughtfully relocated to support the new layout and transformed into a jewel-box moment for guests. Schumacher’s Romantic Bosphorus mural wallpaper creates a hand-painted, immersive experience. A custom console vanity with a Carrara marble top and backsplash pairs beautifully with an antique brass wall-mounted faucet, layered with warm lighting and brass finishes for an unforgettable impression. Beyond the kitchen, we opened up the living room and installed a custom bi-fold door system that seamlessly connects the interior to the screened-in porch, enhancing indoor-outdoor living. A bespoke music room was also created on the main level, complete with integrated soundproofing and custom cabinetry designed to house instruments, sheet music, a piano, and a concealed sound system — allowing the family’s love of music to be fully supported without visual clutter. Throughout the home, existing hardwood floors were refinished, and new decorative lighting and upgraded recessed lighting were installed to elevate both ambiance and functionality. On the bedroom floor, every space received a refresh. Each bedroom was thoughtfully updated with custom wallpaper and wall coverings, while the shared bathroom was fully renovated to incorporate a highly functional laundry area. Durable finishes, smart storage solutions, and a clean layout ensure it works seamlessly for adult children when home while still serving daily needs year-round. The primary bathroom was transformed into a serene retreat designed for daily restoration. A soft neutral palette and layered materials create a calming environment, while half of the space functions as a wet room where the tub and shower share one expansive area. Porcelain tile with a Calacatta marble look delivers timeless elegance without the maintenance of natural stone. Champagne Bronze fixtures complement natural cherry cabinetry — a nod to the homeowner’s passion for woodworking — and thoughtful recessed niches provide clean, hidden storage. Even the attic was elevated to support modern living. Previously underutilized, the space was upgraded to serve as a dedicated home office for the homeowner, who works there daily. Improved lighting, finishes, and function transformed it into a productive and comfortable retreat tucked away from the main living areas. Integrated technology plays a key role throughout the home. A Control4 smart home automation system was implemented to seamlessly manage sound, lighting, and comfort. Custom blinds, drapery, and upholstery were carefully coordinated and fabricated to complement each space, adding softness and cohesion from room to room. This project represents more than a renovation — it is a full reimagining of how the home supports gathering, creativity, comfort, and daily life. Every floor was thoughtfully considered. Every space was elevated. And the result is a sophisticated yet welcoming home designed to serve this family beautifully for years to come.

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.

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.

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!
