21 & 407 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. Two separate parcels (both with deeded beach access), protected by a non-conforming pre-existing rock revetment, offer extraordinary potential in a setting that is as private as it is breathtaking. The main residence is a commanding, nearly 9,000 sq. ft., modern beach house-built with substance and intention. Floor to ceiling walls of glass open the home to the serene ocean landscape, offering uninterrupted views of the Atlantic Ocean and dramatic sunsets over a neighboring pond. Terraces spill out 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. A pre-existing, non-conforming lower level is fully built out with staff quarters, wine cellar, gym, game room and more. The home's scale, quality construction, and excellent condition make it an ideal canvas for reimagination-whether reconfiguring the interior or elevating the existing design to match its surroundings. Directly across the private gravel drive, the 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 is not just a property - it's a true compound - in one of the most coveted oceanfront enclaves in the world.
