Spectacular contemporary waterfront Kistler and Knapp built estate privately sited on 12+ acres off Monument Street. Designed by award-winning Machado Silvetti, known for its distinctive spaces and unique works of architecture, such as the Getty Villa and Bowdoin College Museum of Art. Dramatic and pragmatic, functional architecture plays with light, perspective, and depth to create spaces designed for enjoying the beauty of the surroundings. The clean and calming interior design is sun-drenched, with light pouring in the floor-to-ceiling windows and water views from almost every room. Fully renovated, the gorgeous Bulthaup-designed kitchen features Wolf and Miele appliances, large islands, dual dishwashers, three ovens, a coffee nook, two fridge drawers, and a restaurant-grade hood. Wake up to beautiful water views in the south-east facing primary bedroom suite with an abundance of closet space and a large updated primary bathroom. Unbelievable lower-level exercise studio designed for a pro-athlete and further modified for Pilates/barre class, teak sauna with shower, 2000 bottle wine cellar, and large rec/media room. Four-car garage with electric car charger. One-of-a-kind, this property makes a statement of California chic in an idyllic and convenient New England setting close to Boston, the train, and Hanscom (private airport) while surrounded by 200+ acres of pristine conservation land along the Concord River. Remote access to a unique set of nature trails. A home with function and form: providing lifestyle in a work of art.
