Set up from the street, 1500 Diamond is a quiet retreat with a timeless style and vistas that stretch from downtown to Mt. Diablo. The open floor plan places company rooms'' at the front, while in the back two big bedrooms overlook a flowering garden (the larger is two room en-suite that has also been used as a family room and study). Downstairs, a third bedroom with its side entrance can serve a variety of purposes, from an au pair suite, to the man cave, to a room for the in-laws. The flexible layout also works for entertaining: cocktail soirees for up to 60 guests can be pulled off with panache, along with holiday dinners and neighborhood barbecues in a terraced yard with more spectacular views that will never let you forget where you live.
