About This Home
This quintessential Ditch Plains cottage rests on a rare 0.50-acre buildable, wetland-free parcel south of the highway. It's just mere moments to the surf and lifeguard-attended beaches and minutes to South Lake's lapping shores with its mooring fields. Positioned on a quiet cul-de-sac and bordering an expansive protected nature reserve, the property delivers a level of privacy and natural beauty seldom found in Ditch Plains. The setting captures the essence of Montauk's laid-back coastal lifestyle while offering exceptional development potential. The existing 720SF cottage breathes the beach life with mid-century modern appeal, an open living plan and a glass-walled dining area facing the preserve. The park-like setting welcomes post-surf ocean activities, garden parties, and relaxation within its native landscape dotted with hidden nooks and paths-ideal for immediate enjoyment or as the foundation for a future vision. For those seeking to create a private retreat, the property is a true blank canvas. This rare parcel allows for the design and construction of a secluded compound, with East Hampton Town code allowances for a residence of up to 3,036 SF (1st & 2nd floors) in addition to an expansive finished lower level. Ample expansion possibilities include a pool, pool house, pool patios, an auxiliary housing unit, a detached garage and other accessory structures achievable with sound managed planning. Come explore. Call for details. East Hampton Town Code allowable GFA = 3036 SF.
