Some homes are simply built. Others are designed to change the way you experience nature. This extraordinary 1956 residence by renowned architect David Henken, one of Frank Lloyd Wright's most celebrated apprentices, is one of those rare homes. Privately nestled on more than 17 breathtaking acres above a babbling stream near Teatown Lake Reservation, the home embodies the timeless principles of organic architecture, where walls of glass, natural materials, and thoughtful siting dissolve the boundaries between indoors and out. Built from Philippine mahogany, stone, slate, and glass, every detail was carefully considered to create harmony with the surrounding landscape. The result is a 2 bedroom 2 bathroom home that feels remarkably current nearly seventy years later. Inside, soaring glass walls frame the changing seasons while a dramatic stone fireplace anchors the main living space. Original built-ins, slate floors, rich mahogany, and a signature wraparound deck celebrate Henken's vision, while the thoughtfully updated kitchen and recent improvements allow the home to function beautifully for modern living. Designed using passive solar principles decades before sustainability became mainstream, the home captures the low winter sun for natural warmth while deep roof overhangs provide cooling shade throughout the summer additionally geothermal heating, solar, and other thoughtful updates bring modern all-electric comfort to the home. Complementing the main residence is a beautifully reimagined 1,200 square foot studio that expands the property's possibilities. Completely renovated, the space now offers a bedroom, full bath, living area, kitchenette, and a stunning spa-inspired sauna suite finished with terrazzo tile, warm Aspen wood, and premium contemporary materials throughout. Whether used as a guest retreat, artist's studio, wellness space, home office, or income-producing guest accommodation, it offers the same thoughtful design and craftsmanship found in the main home. Recent improvements, including a newly constructed carport, estate-style gravel driveway, high-performance siding, Energy Star windows, updated insulation, and new mechanical connections to the studio, ensure the property is ready for years of effortless enjoyment. The setting is every bit as extraordinary as the architecture. Wander your own seventeen-acre landscape, listen to the year-round stream, or spend the afternoon exploring nearby Teatown Lake Reservation. Just beyond, you'll find some of the Hudson Valley's most celebrated destinations, including Blue Hill at Stone Barns and The Farmer & The Fish. Nearby towns of Ridgefield, Pound Ridge, Katonah and Bedford, offer exceptional dining, galleries, farmers markets, and hiking. Metro-North provides easy access to New York City, making this an extraordinary full-time residence or one of the region's most remarkable weekend escapes. Architecturally significant homes of this caliber rarely become available. This is more than a residence—it's an opportunity to own a living piece of mid-century design history, thoughtfully preserved for the next generation.
