Honored for its remarkable architectural reimagining with the 2021 HOBI Award for Best New Old Home Remodel, this privately set 6-bedroom estate--originally built in 1804 and rebuilt in 2015 by Roger Ferris + Partners--rests on approximately 2.53 gated acres behind a gracious motor court, pairing classic architecture with contemporary design.
Natural light pours through oversized windows across a seamless open floor plan anchored by a sleek, beautifully appointed kitchen. En suite bedrooms, dual family rooms, a media room, private offices, and a calm, elegantly composed primary suite provide flexibility for every version of life. Multiple fireplaces add warmth throughout. The highly designed grounds by renowned landscape architect Wagner Hodgson feature tiered gardens with wonderfully surprising moments for elevated outdoor living throughout every pocket of the property.
A heated pool, pool house, sun deck, and mature tree line create a peaceful and private enclosure. The architectural
treehouse and sculptural wood jungle gym - that is as much outdoor art as play space - make this Greenwich oasis ideal for recreation and entertainment. Enjoy unbeatable convenience with Downtown Greenwich only 15 minutes away and White Plains Airport just 7 minutes from your door.
A considered home in a preeminent Greenwich setting.
