About this home

Set on 6.58 elevated acres on prestigious Round Hill Rd, this distinguished property—once part of the 200+ acre Wilshire Farms estate—offers a rare opportunity to own a piece of local history. A dramatic, gated quarter-mile driveway past white split-rail fencing leads to a 1910 carriage house. The property includes a 4-bedroom guest cottage, a detached 3-car garage, 3-stall stables, a pool with cabana, and a tennis court. Unique opportunity to own exceptional country retreat and a part of Greenwich history.
