Property Description

Spectacular Mid-Century Architectural Gem! Wood-shingled home designed in 1963 by renowned architect, John Hans Oswalt, owned by the same family for over 60 years! Enter into the stunning living room, with its soaring cathedral ceilings & exposed rafters, floor to ceiling windows, large open-hearth fireplace, crowned by a copper chimney, adjoining den & library. A chalet-like ambiance emanates from rustic wood walls & hardwood floors. Both rooms open to a large deck with expansive views of San Francisco Bay & peekaboo views of SF & bridges. The mid-level has a family room, with its mesmerizing garden views, kitchen that open to a lovely patio & garden, light-filled primary & secondary suites. Downstairs is a 3rd bedroom, bathroom, laundry room & a breezeway that leads to a charming historic cottage, with a bedroom, dining area, living room, bathroom & kitchen. The redwood walls are truly special. This 4 bedroom 4 ½ bath home could easily be described as a 3 bed 3 ½ bath house with a 4th bedroom & 4th bath in a historic cottage/ADU separated from the main house by an enclosed breezeway. From every level, one can enter the magical park-like garden, with its many fruit and ornamental trees, waterfall & pond, landscaping, basketball court/play area, rec space. A true paradise!
