About This Home

As of May 2026

Privacy, lifestyle, and location converge at 1006 Howard Hills Drive in Lafayette’s coveted Upper Happy Valley. Offering a rare sense of seclusion just minutes from BART, commute routes, top-rated schools, and downtown, this updated, light-filled retreat delivers the ideal balance of convenience and escape. Inside, a grand living room and formal dining room set an elegant tone, enhanced by thoughtful updates throughout. The chef’s kitchen features an expansive center island with generous seating, abundant storage, and seamless flow into the inviting family room with fireplace, creating a natural gathering space. Soaring ceilings and walls of glass define the open, airy ambiance, designed for effortless living and entertaining. The floor plan includes three secondary bedrooms on the main level, while the primary suite is privately situated on a subtly elevated level, creating a peaceful retreat. The lower level offers an additional bedroom, a versatile bonus/media room, and a dedicated office or gym. Outdoors, resort-style grounds elevate the experience with a pool, spa, multiple patios, and access to a shared tennis/pickleball court. Additional highlights include owned solar, extensive storage, and a four-car garage. A rare opportunity you won't want to miss!
