Morning routines shouldn’t involve a traffic jam at the sink. The 2025 Houzz Bathroom Trends Study found that 65 percent of U.S. renovators now choose a double-sink vanity to skip the wait. Designers agree: Titan Builders dubbed 2025 “the year of bigger, storage-packed double vanities,” forecasting dual-basin setups in family, guest, and even powder baths. As KBIS 2025 launches land, prototypes for 2026 layer in spa-grade wood, built-in outlets, and planet-friendly finishes. In this guide, we rank six standout models and show you how to size, install, and enjoy a clutter-free, two-sink future.   Methodology and selection criteria   A well-planned double-sink vanity keeps busy morning routines calm and clutter-free.   Before we crowned any winners, we mapped the entire 2024–2026 double-sink (dual-basin) market. That meant parsing KBIS exhibitor releases, scraping bestseller lists from Home Depot, Lowe’s, and Wayfair, and reviewing designer short lists in trade magazines. The sweep produced 110 candidate vanities, giving us visibility into every style, price tier, and material in play.   We then scored each model against six weighted factors that continue to matter long after installers leave:  

1. Build quality – 25 percent.Solid hardwood frames, dovetail drawers, and furniture-grade plywood backs, never particleboard in disguise.  
2. Design versatility – 20 percent.Lines and finishes that suit modern, classic, or farmhouse baths without dating quickly.  
3. Sustainability – 15 percent.FSC-certified wood, CARB 2 compliance, and low-VOC finishes for healthier air.  
4. Storage efficiency – 15 percent.Deep drawers, tilt-outs, or power cubbies that corral countertop clutter.  
5. Value for money – 15 percent.Fair street price for the materials, stone tops, sinks, and soft-close hardware included.  
6. Brand reputation and warranty – 10 percent.Manufacturers with responsive support and at least a one-year parts guarantee.

  Three hard gates kept the field honest: each finalist had to ship in North America by early 2026, include a countertop plus two sinks, and hold a minimum four-star user rating. We also filtered out mass-produced MDF boxes and pay-to-play “editor’s picks” in favor of furniture-grade builds with transparent spec sheets. Double-sink listings on Willowbathandvanity.com spell out hardwood or birch-and-plywood construction, specify when MDF and pressboard are not used, and list dovetail drawer boxes, soft-close hardware, and downloadable spec drawings, the kind of detail that made it easier to confirm build quality and layout before shortlisting a model.   After the cuts, six vanities remained, each leading a different use case: luxury showpiece, budget hero, small-bath savior, tech lover’s pick, farmhouse favorite, or bold-color newcomer. The following sections explain why each model earned its spot and where it may have trade-offs, helping you buy with confidence.   Best overall: Willow “Charlotte” 72-inch solid-teak double vanity   The Willow “Charlotte” 72-inch solid-teak double vanity blends heirloom warmth with a durable marble top and deep storage.   Imagine yacht-grade teak refashioned into bathroom furniture; that is Willow’s Charlotte. Stretching 72 × 22 inches (183 × 56 cm), the cabinet feels built-in yet warms the room with genuine wood grain. Every panel and drawer front is solid teak, not veneer, so the wood’s natural oils resist humidity while MDF competitors swell and peel. Willow sources its teak from FSC-certified plantations and finishes it with low-VOC sealers, earning points for durability and indoor-air health.   Open a drawer and you notice commercial-grade heft: dovetail joinery, full-extension soft-close glides, and storage tall enough for a 10-inch (25 cm) hairspray can. Two under-sink bays flank four center drawers, and the factory-installed 1-inch Carrara marble top arrives pre-drilled for 8-inch widespread faucets, eliminating stone-shop delays.

• Footprint: 72 W × 22 D × 36 H in. (183 × 56 × 91 cm)
• Crated weight: 506 lb / 230 kg
• Street price: about $2,575 with marble top and basins, Q4 2025  

  Reality check: at a quarter ton, Charlotte requires a two-person lift or pro delivery, and marble benefits from yearly sealing. Treat it well and expect decades of service. For a dual-basin centerpiece that blends heirloom character with commercial-grade build, Charlotte sets the benchmark.   Best budget buy: Spring Mill “Emlyn” 60-inch double vanity   Spring Mill’s Emlyn vanity delivers double-sink convenience, a shallow profile and turnkey under-$800 pricing for tight hall baths.   When you want dual-basin convenience without draining the budget, Emlyn delivers. The 60.5 × 18.75 × 32.9 in. cabinet (154 × 48 × 84 cm) arrives fully assembled with its top attached and usually lists between $700 and $800 online. That price is roughly one-third of most mid-tier doubles, a welcome break when tile, plumbing, and lighting costs stack up.   Spring Mill controls costs with painted MDF sides and a laminate backer, yet the finish still feels designer: Admiral Blue or Pearl Gray over Shaker doors, finished with a seamless cultured-marble top. One integrated slab means no grout lines and no undermount rims to caulk.   The trim 18.75-in. (48-cm) depth fits hall baths where standard 22-in. units block door swings. Storage stays simple but useful: two under-sink cabinets plus a pair of full-extension drawers for brushes, toothpaste, and floss.   Treat Emlyn gently and expect five to seven years of service, perfect for rentals, flips, or a stopgap remodel. A quick silicone bead along the back edge stops splash creep, and felt pads prevent metal bins from scratching the resin surface.   Installation suits a single Saturday. Level the feet, connect two 4-in. centerset faucets, and move on to paint touch-ups; no stone-shop scheduling or custom templates required. Dollar for dollar, Emlyn delivers more visual impact than any budget vanity in our test group.   Best for small spaces: Allen + Roth “Haverhill” 48-inch weathered-oak double vanity   Allen + Roth’s Haverhill vanity squeezes dual sinks and barn-door storage into a space-friendly 48-inch footprint.   Small bathroom, big wish list? Haverhill packs dual-basin convenience into a 48 × 22 × 34.8 in. frame (122 × 56 × 88 cm) without feeling cramped. Its signature move is a sliding barn-style center door that glides sideways, preserving clearance in tight rooms.   The cabinet uses a plywood core wrapped in hand-distressed oak veneer, finished in a soft weathered gray that pairs with matte-black or brushed-nickel fixtures. A pre-sealed black engineered-stone top shrugs off splash marks; a quick wipe keeps it spotless.   Storage surprises: two under-sink bays plus three full-extension drawers provide soft-close hardware and a rock-solid feel.   Trade-offs: basins sit close, so elbows can bump, and the dark top highlights toothpaste specks; keep a microfiber cloth handy. For condos, kids’ Jack-and-Jill baths, or any remodel where walls refuse to move, Haverhill delivers two sinks in the footprint of one.   Quick specs

• Footprint: 48 W × 22 D in. (122 × 56 cm)
• Height: 34.8 in. (88 cm) with backsplash
• Sliding barn door plus 3 drawers
• Pre-drilled 8-in. faucet spacing, sinks included

  Best smart vanity: OVE Decors “Tahoe III” 60-inch midnight-blue double vanity Tired of cord clutter? Tahoe III fixes it. Each top drawer holds a UL-listed power bar with four outlets and two USB ports, so razors, toothbrushes, and hair tools stay plugged in yet out of sight.     Tahoe III tucks power outlets and grooming tools into the top drawer, keeping the double-sink countertop blissfully clear.   Built with solid-wood rails and furniture-grade plywood, the cabinet wears a velvety midnight-blue lacquer and a 1.25-in. (3 cm) sealed quartz top that shrugs off spills. Interior organizers sort cotton pads and clippers, while a heat-safe holster stores a hair dryer.   An integrated junction box connects to a nearby GFCI in minutes. Soft-close drawers, adjustable shelves, and full-extension glides complete the premium feel.   Quick specs

• Footprint: 60 W × 21 D × 34 H in. (152 × 53 × 86 cm)
• Integrated power: 4 AC + 2 USB, UL-listed
• Crated weight: 300 lb / 136 kg
• Street price: about $2,349 at Home Depot, Q4 2025  

  Factor in professional delivery and install, and reviews still praise the “zero-countertop-clutter” payoff. For households running on devices, Tahoe III pairs dual-basin style with built-in smarts.   Best modern farmhouse: Water Creation “Paisley” 72-inch rustic-sienna double vanity   Water Creation’s Paisley vanity brings warm Rustic Sienna wood and apron-front basins to a modern farmhouse bath.   Farmhouse rooms often rely on painted shiplap, while Paisley flips the script with warm hardwood in a Rustic Sienna stain, topped by crisp Carrara marble and two apron-front basins for equal parts country charm and boutique-hotel polish.   Built from solid birch and oak with undermount soft-close glides, the 72 × 22 × 34 in. cabinet (183 × 56 × 86 cm) leaves space for perfume on the left, a beard trimmer on the right, and still provides breathing room. Three center drawers keep razors separate from hair ties, while each under-sink bay includes an adjustable shelf for tall bottles. Oil-rubbed bronze pulls ship standard, and the 8-32 screw pattern works with most aftermarket knobs.   Marble benefits from a yearly sealer and quick wipe-downs, and it rewards care with timeless style. The vanity arrives fully assembled; crate weight sits near 380 lb / 172 kg, so confirm doorway widths and recruit lifting help. Street price averaged $2,299 at Home Depot in late 2025.   Quick specs

• Footprint: 72 W × 22 D in. (183 × 56 cm)
• Height: 34 in. (86 cm) plus 4 in. backsplash
• Counter: 1 in. Carrara marble, apron-front sinks included
• Hardware: oil-rubbed bronze, soft-close doors and drawers  

  For remodels inspired by barn doors, patterned cement tile, or reclaimed wood accents, Paisley anchors the look and delivers long-term durability.   Best statement color: Kohler “Tone” 60-inch double vanity (2026 preview)   Kohler’s upcoming Tone vanity brings hotel-inspired color and a waterfall quartz top to double-sink baths.   After a decade of white and gray, rich color returns, and Kohler’s upcoming Tone vanity moves it into the mainstream. Slated for Spring 2026, according to product managers at the KBIS 2025 press briefing, the collection wraps a Shaker shell in hotel-inspired finishes: Forest Green, Deep Terracotta, and Midnight Teal.   Design touches match the drama. Brushed-gold pulls, a waterfall quartz top that folds over both sides, and razor-thin 3 mm door reveals create a tailored look. Beneath the lacquer, a solid-poplar frame and furniture-grade plywood mirror the proven Kohler Jute recipe, so strength keeps pace with style.   Inside, adjustable dividers, a bamboo organizer tray, and soft-close hardware rated for 50,000 cycles control clutter. Engineers also added a slim power bank behind the top drawer for charging shavers or phones. Shipped in two main pieces (base and top), Tone can navigate stairs more easily than fully assembled units.   Quick preview specs*

Use the grid for quick elimination, then check the detailed reviews; warranty, service quality, and installation quirks often decide the final pick.   Buying guide: how to pick the right double vanity Measure first, mood-board later. A comfortable dual-basin vanity requires at least 60 in. (152 cm) of wall, plus a few extra inches so doors and drawers clear. In narrow baths, depth becomes the deal breaker. Units measuring 21 in. (53 cm) or less keep morning traffic moving.     Use at least 60 inches of wall, a shallow depth in narrow baths and 30 inches of clear floor space in front of your double-sink vanity.   Plumbing reality check. Converting a single to a double adds a second drain and tees off the hot- and cold-water lines. Floor-exit pipes favor a back panel you can notch, while wall-mounted vanities depend on in-wall supplies and solid blocking for support.   Materials equal lifespan. Solid hardwood and furniture-grade plywood shrug off steam, whereas particleboard swells. If budget points to MDF, seal every raw edge with caulk on day one; the barrier can add several extra years.   Storage style vs. plumbing clutter. Drawers keep makeup and chargers tidy but steal space where P-traps sit. Cabinets swallow tall bottles yet turn into black holes unless you add rollout trays. Many households choose a hybrid: drawers in the center, doors beneath each sink.   Top talk. Marble feels luxe but benefits from annual sealing. Quartz costs a bit more yet laughs at self-tanner and curling-iron heat. Seamless cultured-marble tops lower cost and simplify cleaning, though they scratch more easily.   Accessibility and clearance. Maintain at least 30 in. (760 mm) of clear floor space in front of the vanity to satisfy ADA guidelines and allow two people to bend without bumping hips. ADA also requires floating units to offer 27 in. (685 mm) of knee space for wheelchair users.   Last, vet the brand. A vanity proves its worth when a company can overnight replacement hinges after a move. Established manufacturers publish part numbers and answer the phone, peace of mind worth a small premium.  

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!

A 1927 colonial home in Shaker Heights, Ohio, received a breathtaking renovation that required extensive work, transforming it from a tucked away, utilitarian space, to an all-purpose gathering room, a role that most kitchens embrace in a home today. The scope of work changed over the course of the project, starting more minimalistically and then quickly becoming the main focus of the house's remodeling, resulting in a staircase being relocated and walls being torn down to create an inviting focal point to the home where family and friends could connect. The focus of the functionality was to allow for multiple prep areas with the inclusion of two islands and sinks, two eating areas (one for impromptu snacking and small meals of younger family members and friends on island no. two and a built-in bench seat for everyday meals in the immediate family). The kitchen was equipped with all Subzero and Wolf appliances, including a 48" range top with a 12" griddle, two double ovens, a 42" built-in side by side refrigerator and freezer, a microwave drawer on island no. one and a beverage center and icemaker in island no. two. The aesthetic feeling embraces the architectural feel of the home while adding a modern sensibility with the revamped layout and graphic elements that tie the color palette of whites, chocolate and charcoal. The cabinets were custom made and outfitted with beaded inset doors with a Shaker panel frame and finished in Benjamin Moore's OC-17 White Dove, a soft white that allowed for the kitchen to feel warm while still maintaining its brightness. Accents of walnut were added to create a sense of warmth, including a custom premium grade walnut countertop on island no. one from Brooks Custom and a TV cabinet with a doggie feeding station beneath. Bringing the cabinet line to the 8'6" ceiling height helps the room feel taller and bold light fixtures at the islands and eating area add detail to an otherwise simpler ceiling detail. The 1 1/4" countertops feature Calacatta Gold Marble with an ogee edge detail. Special touches on the interiors include secret storage panels, an appliance garage, breadbox, pull-out drawers behind the cabinet doors and all soft-close hinges and drawer glides. A kneading area was made as a part of island no. one for the homeowners' love of baking, complete with a stone top allowing for dough to stay cool. Baskets beneath store kitchen essentials that need air circulation. The room adjacent to the kitchen was converted to a hearth room (from a formal dining room) to extend the kitchen's living space and allow for a natural spillover for family and guests to spill into.

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.

Note the large scale tile juxtaposed against the quilt style tile on the oven wall. This large and simple toned grey field allows the other area to stand out, yet this window wall detail also serves a purpose of showing how every area can be unique, but not glaring in contrast.
