About this home

Once part of the A.G Vanderbilt and C.V. Whitney Wychwood Estate, the converted carriage house sits on 5 very private acres. The interior is clad in custom millwork throughout. The heart of the house is the sun-filled gourmet chef's kitchen, attached family room and dining room featuring an oversized center island, butler pantry, built in banquette, see through fireplace and a double set of french doors overlooking the bluestone patio and expansive yard. The primary suite is an entire wing of the home. Three additonal bedrooms with 2 full bath complete this wing. A separate 1 bedroom suite with den is a wonderful private guest area on its own wing. A Ludovici clay tile roof is simply breathtaking and gives an aire of romance to this unique home. Additional 4 Bedroom, 1.5 bath guest caretakers cottage with a cozy farmhouse kitchen, dining room, living room and outside terrace complete the unusual complex.
