Built in 1962 by celebrated modernist architect Andrew Geller, this 3-bedroom, 3.5-bath home sits on a meadowed, shy acre and is filled with Geller’s signature design elements and abundant natural light. In 1982, Geller himself oversaw a thoughtful expansion, seamlessly blending the new spaces with the original vision. The whimsical property features a beautiful gunite pool with expansive decking and a dramatic concrete retaining and privacy wall. Just a mile from Bailie Beach, Rose Hill Vineyard, and Love Lane, it is ideally positioned to enjoy all the North Fork has to offer.
