About this home
2008 ADDITION & RENOVATION TO THE STUDS - THIS HOME WAS REBUILT FROM THE GROUND UP. Understated elegance is the hallmark of this gorgeous home which lends itself equally to the demands of daily life, or the serenity of a weekend escape. The beautifully proportioned principal rooms invite both formal entertaining, and relaxed family living. The gourmet kitchen is a chef's delight, boasting 4 ovens, 3 dishwashers, ample refrigeration and exceptional storage capacity. 5 generous en suite family bedrooms, all on the second floor, are complimented by a primary suite with two baths. The magnificent grounds feature a beautiful terrace, heated pool, formal garden, & year round working greenhouse. Theater, playroom, wine cellar & 3 car heated garage. 266 Round Hill is truly a showstopper.
