10 Deer Island Lane, Novato, CA, 94945
About This Home
A rare near six-acre estate (3 ~2 acre parcels) atop a private hill, this 4,760 sq ft custom home offers 5 bedrooms, 3 baths, and sweeping views from every window, all just minutes from Highways 37 and 101 and downtown Novato. The main level centers on a cathedral-ceiling living room with fireplace, a chef's kitchen with breakfast area and family room, a formal dining room with butler's pantry, and two south-facing decks. The primary suite opens to its own deck and includes two walk-in closets, dual vanities, a marble shower, and a jetted tub. Two more bedrooms (one ideal as an office), a full bath, a spacious laundry room, and an attached three-car garage complete the floor. A lower level with its own private entrance, full kitchen, two bedrooms, dual-sink bath, two-car garage, and a patio with putting green is ideal for guests, multigenerational living, or rental income. The grounds are equally impressive: sunrise views toward Mt. Diablo, a rose garden, fruit orchard, and reflecting the estate's equestrian origins, a six-stall barn with foaling and tack rooms, plus cross-fenced pastures. Radiant floor heating, air conditioning, tile flooring throughout, and extensive parking round out a truly exceptional offering.
