Located moments from Sag Harbor Village, this rare 0.33-acre through-lot on Main Street presents a fully approved, opportunity with exceptional scale and flexibility. The property is offered with full approvals from the Sag Harbor Village Architectural Review Board and Zoning Board of Appeals, as well as Suffolk County Department of Health, allowing construction to begin immediately. Approved plans include a +/- 4,000 SF main residence and a detached 600 SF accessory dwelling unit, creating a 7-bedroom, 5.5-bath compound totaling +/- 4,600 SF. The main house features an open-concept living design anchored by a sun-filled kitchen and living area, a spacious first-floor primary suite with direct access to the rear deck and pool, and four additional bedrooms on the second level. Outdoor living is centered around a 16’ x 32’ gunite pool, landscaped grounds designed for both entertaining and everyday living, and a front porch with unobstructed views of Mashashimuet Park. The detached two-bedroom ADU offers a complete secondary living experience with its own kitchen, great room, and private driveway access on Fordham Street—ideal for guests, a home office, or legal rental use. A rare opportunity to secure a fully entitled Main Street estate just moments from Sag Harbor Village shops, dining, and marinas, with the ability for a buyer to customize the final product prior to construction.
