This green eco-friendly home is set in the midst of more than 16 acres of beautiful meadows at the point where Connecticut's Hollenbeck River meets the wild and scenic Housatonic on its journey toward Long Island Sound. Built to fully embrace and appreciate its protected breathtaking panoramic views, the river and mountains can be seen from almost every room on all floors. An elevator connects the four levels of living space. Built for a renowned environmental scientist, this energy efficient home has an attached heated two car garage, a 4-zone, geo-thermal HVAC system and low-e/argon windows with transoms designed for maximum lighting and solar gain, and creative integration of reclaimed, vintage architectural elements. The chef's custom kitchen boasts granite countertops and restaurant quality appliances, including a gas-fired Wolf range. The light-filled living and dining rooms feature 9 feet ceilings and sliding doors that open onto multi-level decks, built of sustainably harvested ipe wood, overlooking the river. The master suite, known as the cloud room, is situated at the highest point of the house, with sweeping 300 degree views of the river valley. There are two additional bedrooms with a third possible on the ground floor, three full baths, and writer's study with a floor to ceiling built-in bookcase library. The house was designed to minimize its impact to the surrounding lands; its vertical design and efficiently arranged living spaces represent a conscious effort to reduce the structure's impact to the surrounding environment. A three stall horse barn is located at the southern end of the property. The Metro North rail station is 30 minutes away, and Hotchkiss, Berkshire, Indian Mountain, and Salisbury private schools are within minutes of the property. Nearby are the towns of Millerton, NY and Great Barrington, MA. This property would make an ideal country retreat or year round home.The grounds are a carefully curated arboretum of unique trees and plants from around the world. Every new planting, border stone, and tree has been placed respecting the diversity of that specific habitat, considering the river, the wildlife, and the surrounding environs. Documentation of this design and conservation strategy is available to the new owners at closing. It is possible to add a second barn and possibly a guesthouse to this property, pending local approvals.
