Nestled within one of North Haven's most desirable enclaves, just moments from Sag Harbor Village, this exceptional 0.60± acre property offers the rare opportunity to enjoy today while planning for tomorrow. The existing single-level residence features three bedrooms, two full bathrooms, vaulted ceilings, open-concept living and dining spaces, a rear entertaining deck, laundry room, and an attached one-car garage. Outside, a heated gunite pool and mature landscaping create a private retreat that can be enjoyed immediately as a year-round home, weekend escape, or investment property. For those seeking to create something entirely their own, the property offers outstanding redevelopment potential. 100% cleared, the parcel is approved for the construction of a custom residence spanning approximately 4,300± square feet across three finished levels. Current approvals allow for up to six bedrooms, five full bathrooms, one half bath, a recreation room, study, and expansive indoor-outdoor living spaces.

Located just moments from Sunset Road beach access, the Shelter Island Ferry, and the shops, restaurants, marinas, and waterfront charm of Sag Harbor Village, this offering combines an unbeatable location with lasting value. Few properties present the opportunity to move in and enjoy immediately, renovate over time, or build a bespoke Hamptons retreat from the ground up-all in one of North Haven's most sought-after neighborhoods.
