About This Home
As of December 2025This is more than a home—it's a living work of art. Come and see the recent updates, including fresh new painting throughout, as well as enhanced landscaping and outdoor lighting. The extraordinary residence functions beautifully for family living but originally it was a 200-year-old barn transformed in 1973 by acclaimed architect Charles Gwathmey, blending rustic heritage with bold modernist design. The home showcases Gwathmey's signature sculptural details, including glass block walls and an interior silo encircling a dramatic spiral staircase. The centerpiece is a breathtaking 30' x 35' great room with soaring beamed ceilings, a massive fireplace, and natural light pouring through expansive windows. The property has since been thoughtfully expanded by its current owners and was featured in Architectural Digest in 2005. Set on a secluded mid-country acre, the home offers five bedrooms and a seamless indoor-outdoor flow that invites year around entertaining. Designed with both style and practicality in mind, the layout offers generous gathering spaces, private retreats, and a backyard oasis with mature specimen plantings, pool, spa, firepit, grill, bar and covered lounge area. Every detail, from the architectural pedigree to the lifestyle amenities, reflects a rare fusion of history, innovation, and artistry.
