In a desirable North Haven enclave just moments from Sag Harbor Village, this 0.60-acre property presents both immediate comfort and a rare redevelopment opportunity. The existing single-level home has 3 bedrooms, 2 full baths, vaulted ceilings, open living and dining spaces, a rear deck, laundry, and an attached one-car garage. The property is further enhanced by a sunny heated gunite pool and mature landscaping, creating a private retreat ready to be enjoyed. The true value lies in the long-term vision. Cleared and grandfathered, the parcel allows for the creation of a 2-story home with a finished lower level and accessory structure totaling 5,000 +/- sq. ft. This flexibility provides a rare opportunity in North Haven to design and build a contemporary estate with expansive entertaining areas, multiple bedroom suites, recreation spaces, and outdoor amenities tailored to your lifestyle. Few properties offer such a combination of move-in-ready enjoyment today and a generous framework for future luxury construction. Set within reach of Long Beach, Sunset Road beach access, the Shelter Island Ferry, and Sag Harbor Village's vibrant shops, dining, and marinas, this offering blends location, privacy, and potential. Whether cherished as it stands or reimagined into a custom Hamptons retreat, it is an exceptional chance to secure a North Haven address with enduring value.
