luxury architect houses for sale Southampton, United States

Nestled in an exclusive beachside enclave with private access through a serene park setting, this architect-designed mid-century Modern home is a true work of art. With private community beach access, this 4-bedroom, 3-bath spacious home offers 3,286 sq ft. of living space. Created by a renowned architect as his personal sanctuary, the home draws on the timeless philosophy of Frank Lloyd Wright—seamlessly blending nature, form and function.

Masterfully conceived and executed by Daniel B. Scotti Design & Development, this custom estate is privately set on nearly an acre along a quiet lane in Wainscott, just 1.25 miles from Beach Lane. Encompassing approximately 8,000 square feet across three beautifully finished levels, the six-bedroom residence combines classic Hamptons architecture with exceptional craftsmanship and a highly considered, turnkey interior. Bespoke details define the home, including 9-inch-wide natural white oak floors, custom tongue-and-groove millwork, Kolbe windows, and three fireplaces. The main level flows from a gracious entry foyer to generously proportioned living and dining rooms, a comfortable family room, a private den or office, and a beautifully appointed junior primary suite. At the center of the home, the open chef's kitchen is appointed with custom Ciuffo cabinetry and hardware, a 48-inch Wolf range, a 48-inch Sub-Zero refrigerator, refrigerated drawers, beverage and wine storage, and two Miele dishwashers. Upstairs, the primary suite is a true private sanctuary, complete with dual walk-in closets, separate baths, radiant-heated floors, and English fittings by Barber Wilsons and Lefroy Brooks. The second floor also offers three additional en-suite bedrooms. Designed for entertaining, the expansive finished lower level functions as a private club, offering a fully equipped gym, theater, climate-controlled wine cellar, media and billiards lounge, and an additional en-suite guest bedroom. Outside, the fully private, south-facing grounds are framed by mature landscaping and anchored by a 20-by-48-foot heated gunite pool and spa. Expansive bluestone patios, a covered loggia with an outdoor brick fireplace, a built-in 54-inch Wolf barbecue, and a half basketball court create an exceptional setting for summer living and entertaining. A detached two-car garage completes the exterior. Additional amenities include copper gutters, laundry facilities on two levels, central vacuum, five-zone HVAC, an upgraded whole-house and outdoor Sonos system, and a discreetly positioned full-house generator. Freshly painted inside and out in 2026, this is an unusually complete Wainscott offering that delivers scale, privacy, craftsmanship, and proximity to the ocean without compromise.

The pinnacle of Luxury Living In the historic heart of Sag Harbor — a village shaped by its storied whaling past and now celebrated for its cultural sophistication — Residence A stands as a singular architectural statement along one of the most coveted stretches of waterfront. Commanding approximately 250 feet of prime frontage on the harbor, this exceptional estate is far more than a home; it is a four-level masterwork of glass, stone, and light, created for a global buyer seeking complete privacy, effortless luxury, and direct nautical access. This extraordinary property is the result of a visionary collaboration between J. Bialsky of Bialsky Premiere Design & Development and the internationally acclaimed Hollander Design Landscape Architects. Together, they have crafted a residence that exists in perfect harmony with the Peconic Bay — a seamless dialogue between architecture, landscape, and water. Every line is intentional, every perspective framed, and every material selected to endure the coastal environment while maintaining an elevated, timeless aesthetic. Spanning an impressive 16,974 square feet across four levels, the estate is conceived as a vertical sanctuary where grand-scale entertaining and intimate retreat coexist effortlessly. Interiors encompass approximately 12,551 square feet of meticulously designed living space, defined by a palette of organic textures, refined finishes, and state-of-the-art systems. The residence offers eight expansive bedroom suites and ten beautifully appointed baths, thoughtfully arranged to accommodate family, guests, and live-in staff with complete comfort and privacy. Outdoor living unfolds across multiple levels of tiered terraces and lounge decks, creating a dynamic al fresco experience that keeps the water constantly within view. At the pinnacle, a private rooftop sanctuary serves as a crowning architectural achievement — featuring a pool and spa seemingly suspended above the harbor, offering uninterrupted 360-degree vistas and breathtaking sunset views across Sag Harbor’s golden coastline. For the yachting enthusiast, the property delivers a level of functionality rarely found in village waterfront estates. A private, deep-water marina includes two 60-foot boat slips, placing you at the center of the Hamptons’ maritime lifestyle with immediate access to the open Atlantic and the protected waters of Shelter Island Sound. Beyond its beauty, the residence operates with the precision of a modern high-security retreat. A rare private garage provides secure parking in the heart of the village, while fully integrated smart-home technology manages climate, lighting, and security seamlessly from anywhere in the world. Turn-key in every sense, Residence A represents a rare convergence of location, design prestige and waterfront capability — an exceptional offering for the most discerning buyer seeking a legacy property in one of the Hamptons’ most iconic destinations.
