About This Property

One of Larchmont Manor's most magnificent 19th-century estates, this one-of-a-kind property  has been meticulously preserved and remodeled over the years, flawlessly maintaining its exquisite original architectural details while integrating high-end contemporary comforts. As one of the Manor's largest and most significant properties, the residence serves as a private "camp for all ages," featuring an expansive 22 x 45-foot heated pool, a tennis court, and a series of porches and patios designed for grand-scale entertaining or quiet reflection amidst the lush, secluded grounds. Designed by Frank Ashburton Moore, who designed other manor homes as well as all of Larchmont's major municipal buildings, every corner of the home showcases exquisite original architectural details, offering a rare sanctuary of scale and craftsmanship. Eight spacious bedrooms provide an abundance of space. Each room maintains the home's hallmark historical elegance while offering the versatility required for modern living. The lush, secluded grounds provide total privacy, yet the estate remains just a stone's throw from village shops, restaurants, local clubs, and Chatsworth Avenue Elementary School. This premier location offers the perfect balance of serene seclusion and vibrant community living. Whether enjoying the sprawling outdoor amenities or the refined interior, this home represents a rare opportunity to own a piece of history in a location that is truly second to none.
