About This Home
As of March 2026Secluded in the hills of Upper Happy Valley, this Mediterranean villa is a private world of resort-style living, amid landscaped grounds framed by sweeping Mt Diablo views. The estate feels worlds away, yet is minutes from downtown Lafayette. Walls of glass frame panoramic mountain vistas. The elegant bar room evokes a club’s ambiance. The dining room, with a beamed ceiling and seating for up to 12, flows into the rotunda, a room ideal for cocktail gatherings. Nearby, a spiral staircase leads to an impressive office suite, with 4 chandeliers, windows on 3 sides and Mt Diablo views. The chef’s kitchen offers elite appliances, custom counters, fine cabinetry and a breakfast nook. The family room features a 7x12-foot projection screen. The principal suite commands sweeping views of the deck, pool and Mt Diablo. Another bedroom is a second principal suite, secluded for privacy. One of the 2 additional bedrooms opens directly to the garden: fountains, tropical landscaping, a sport court and massive deck. The adjacent guest house can be used as a yoga studio, gym, or bedroom suite. The outdoor bar seats 6 beside a DCS grill, and a hot tub is in a secluded deck corner. The tile roof is beautiful and fire resistant, and the fire station is just down the hill.
