Walls of glass in the current 5-bedroom residence open to a spectacular deck with pool and panoramic views. Once part of the 43-acre Edgar Marston estate, the property includes c.1885 Queen Anne-style cottage with sleeping loft, kitchenette, and full bath -the only remaining structure from one of Greenwich's Great Estates.
