About This Home
Famed architect Boris Baranovich designed this extraordinary stone Georgian estate of 26,000+/- square feet on 8.788 secluded acres off of Round Hill Road. Exquisitely executed, this stately manor home offers eight bedrooms and twelve full and five half bathrooms throughout four levels of living space. Mature trees and lush lawn surround this exceptional estate with two gated entrances: one to the formal parking court and one for service/deliveries. Beautifully appointed interiors feature eight wood-burning fireplaces in the elegant foyer, living and dining rooms, family room, sunroom, library, and primary suite. There are six upper-level bedrooms in addition to the primary suite, plus a private guest apartment. The third floor is comprised of staff quarters, a playroom and storage. Designed for entertaining, the lower level features a regulation squash court, a billiard/game room, professional 12-seat home theater, gym, climate-controlled wine cellar, kitchenette, full spa bathroom and dramatic indoor pool and Japanese soaking tub. There are two attached garages adjacent to the mudroom. Connected by a breezeway is a detached garage with two additional bays and two car lifts. Bonus office with separate private entrance and private power room. A guest apartment with private entrance offers an en-suite bedroom, kitchenette and sitting room. Overlooking the gorgeous backyard, French doors open to the rear stone terraces. Perfect for indoor/outdoor entertaining is a pergola-covered outdoor dining area with built-in grill and firepit. The sunroom and "pool cabana" rooms open to the spectacular outdoor pool with automatic cover.
A extraordinary opportunity to buy an irreplaceable Greenwich estate offering luxurious, resort-style living in the heart of back country.
