When you think of mid-century modern, this is the home that comes to mind. The iconic Double-A designed by A. Quincy Jones, and built by Eichler homes in 1963. This stunning example of MCM architecture is one of the most popular of all Eichler models with its versatile floor plan of 5 bedrooms and 2 bathrooms that surround the spacious open air atrium and signature great room that epitomize the Eichler spirit of bringing the outdoors in. Features include double pane windows throughout, multiple skylights, wood burning fireplace, insulated roof under warranty, updated period flooring, fresh exterior and interior paint in designer colors, radiant heating, large single car attached garage with automatic door, covered carport, fully fenced back and side yards, additional exterior storage, and programmable irrigation. Located high atop the hill on peaceful Highwood Road in Castro Valley's wonderful Greenridge neighborhood. Great weather, central location, and plenty of parks and recreation.
*Taxable value of land and structures on it ("additions") is determined regularly by local assessors and does not affect market price.
