A neoclassical brick and limestone mansion built in the early 1990s, Fessenden House is located in the affluent Forest Hills neighborhood.

The home was designed by Leon Chatelain of Chatelain Architects in collaboration with interior designer Antony Childs.

Outside, the grounds include formal and informal English gardens, hedges and fountains. There is also a pool, pool house and a sports court.
