21 Fairfield Pond Ln With approximately 200 feet of direct ocean frontage on one of Sagaponack's most private and prestigious lanes shared by only three other homes, this is a generational opportunity rarely seen on the East End. The existing modern beach house is a commanding, nearly 9, 000 sq. ft. home built with substance and intention. Walls of glass open the home to the serene ocean landscape, offering first floor views of the Atlantic Ocean and dramatic sunsets over a neighboring pond. Terraces spill out at ground level toward a pool, spa, and wildflower meadow that runs all the way to the dunes, where a pre-existing (and grandfathered) pavilion and private stairs deliver you directly to one of the widest stretches of beach in the Hamptons. The home's scale, quality construction, and excellent condition make it an ideal canvas for reimagination- whether simple enjoying as is, updating the luxurious interior or elevating the existing design to current standards and styles to match its surroundings. Alternate, the home could be completely rebuilt within a generous building envelope. Directly across the private gravel drive, a second parcel offers a blank slate with deeded ocean access and its own executive golf course. It's perfectly suited for a guest house, expanded estate grounds, or added amenities like tennis and pickleball. This property offers luxury and opportunity that few oceanfront homes can match anywhere in the Hamptons.
