A rare architectural offering in the heart of Old Westbury, 15 Horseshoe Road is a striking Norman Jaffe-designed residence where dramatic form, natural materials, and the surrounding landscape come together in extraordinary fashion. Set on over two beautifully landscaped acres, this distinctive 5-bedroom, 7-bath home offers exceptional privacy, expansive outdoor living, and a spectacular 25' x 50' gunite swimming pool, all within one of Long Island’s most prestigious communities. From the moment you enter, Jaffe’s unmistakable architectural vision is on full display. A dramatic foyer with soaring approximately 30-foot ceilings and a skylight introduces a home defined by sculptured curved walls, dramatic angles, stone floors, warm pine ceilings, and walls of glass that create a remarkable connection between the interior and its natural surroundings. The expansive living room features newly refinished hardwood floors, a dual-sided fireplace, and oversized glass doors opening directly to the rear deck and pool grounds. Three fireplaces throughout the residence, including two wood-burning fireplaces, add warmth and character to the home’s dramatic living spaces. Extensive glass captures panoramic views of the property and floods the interiors with natural light, allowing the landscape to become part of the architecture itself. Designed for both grand-scale entertaining and comfortable everyday living, the home features a dramatic dining room overlooking the living space and pool area. A generously sized eat-in kitchen with a large center island and counter seating also leads directly to the rear deck. Granite, stone, wood, and glass are thoughtfully incorporated throughout, reflecting the organic modernism for which Jaffe’s work is celebrated. A dedicated home theater provides an additional space for entertainment and relaxation. Outside, more than two acres create a private, resort-like setting with mature landscaping, expansive decks and patios, and a 25' x 50' gunite swimming pool heated by a brand-new propane system. The grounds have been fully restored and are professionally maintained weekly, complemented by a new irrigation system. Multiple indoor and outdoor gathering spaces make the property equally suited for intimate evenings or large-scale entertaining. More than simply a residence, 15 Horseshoe Road is a compelling example of modern American architecture. A truly unique Old Westbury property offering scale, privacy, dramatic design, exceptional outdoor amenities, and a remarkable relationship between home and landscape.
