About this House

Gently tucked away off Valley Road at the base of one of the many hills along the Mianus River, you will find this distinguished classic center hall colonial, glowing with enduring elegance. Beyond the welcoming two-story foyer accented by a bejeweled crystal chandelier, step into this impeccably crafted Cos Cob home perfect for entertainment and gatherings, with a profound balance of comfort and modern convenience. Sparkling sunlight streams through generous windows throughout the house, making this custom built one-owner home light and bright. The wainscotting, abundant recessed lighting, the various trayed, beamed and over nine foot ceilings everywhere and polished hardwood floors throughout suggest a majesty and grandeur in the most subtle and charming way. The welcoming outside stairs beckon you from the rare Valley Road adjacent front yard with a sweeping willow, classic stone wall and a seasonal breathtaking view of the Mianus River. Professional outdoor lighting glorifies evenings on the patio. A private elevator from right inside the three-car-garage to every floor provides convenience and ease of living. Rarely does a home so gracefully combine traditional architecture with modern living. The spacious and well-appointed kitchen with gourmet stove and custom appliances accented by an island and marble and quartz counters opens right to a fireplaced family room for informal entertainment. One step out from the kitchen and family room is the terraced back yard (front and back yards enjoy an irrigation system) with two field stone patios set against a stunning rock wall, affording perfect ambiance for outdoor get togethers. For more formal gatherings, this home also provides a separate dining room adjacent to the kitchen and sunny living room.
Upstairs, the grand primary bedroom is spacious, with three walk-in closets, a Palladian window offering a wonderful seasonal view of the Mianus River and large willow tree, a gas fireplace and vaulted ceilings; desk and sitting space abound here. The ensuite bathroom has a radiated floor, a steam shower and marble bath. Across the hall, beyond another full bathroom and dedicated laundry room, there are two separate and well-sized bedrooms that present comfort and space for their occupants.
On the lower level, there is a huge family space with a large closet and another full bath, a truly perfect place for entertaining, playing or even another bedroom - options abound!
This beautiful home is just minutes away from the Greenwich Water Club and other boat marinas, a local metro north train station, schools, shopping and dining in Cos Cob or along Greenwich Avenue. Updates include a new HVAC system.
