    What's special

    Private terraceWide-plank white oak flooringFully finished lower levelsDual marble islandsHeated gunite poolCentral heating and coolingFirst-floor junior primary suite

    A rare opportunity to own two newly built luxury estates side by side, offering a combined 16 bedrooms, 14 full bathrooms, and 4 half bathrooms across more than 17,000 square feet of living space. Privately positioned at the end of a long flag lot and spanning just under 4 acres, this exceptional compound delivers scale, privacy, and contemporary elegance in one of the most coveted areas of the Hamptons. Each home sits on a separate 2-acre parcel and is slated for late summer completion. With striking curb appeal and all custom, high-end exterior materials, the architecture makes a bold, modern statement-728 Sag Harbor features rich red cedar siding, while 730 Sag Harbor is clad in Alaskan yellow cedar. Inside, dramatic double-height foyers and oversized Marvin windows flood the interiors with natural light, highlighting wide-plank white oak flooring and a refined, minimalist aesthetic. At the heart of each residence is a grand open-concept great room flowing into a designer chef's kitchen with dual marble islands, top-tier appliances, and custom cabinetry. Formal dining rooms offer elegant entertaining space, while bright breakfast areas and covered bluestone patios encourage seamless indoor-outdoor living. Each home features its own heated gunite pool and inset spa, set amid lush, private grounds. Each estate includes eight bedrooms, seven full bathrooms, and two half bathrooms, with a first-floor junior primary suite and a spectacular second-floor primary retreat featuring a fireplace, private terrace, oversized walk-in closets, and a spa-caliber bath with soaking tub, waterfall shower, and makeup vanity. Upstairs also offers additional en-suite bedrooms, a lounge, beverage center, and full laundry. The fully finished lower levels further elevate the experience with custom wet bars, private screening rooms, fitness studios, and additional guest suites connected by Jack-and-Jill baths. Other features include two-car garages, multiple laundry rooms, central heating and cooling, and a crushed gravel driveway-underscoring the thoughtful design and flawless execution throughout. Perfectly located between East Hampton and Sag Harbor, 728 & 730 Sag Harbor Turnpike present a truly rare opportunity to own two architecturally significant, ground-up new homes-ideal for entertaining, large-scale hosting, or creating the ultimate private retreat. Live in one. Host in the other. This is Hamptons luxury at its most complete.
