About this home
Exceptional Custom Home. Set against beautiful Walnut Creek hill and valley views, this spacious home offers exceptional versatility.

Highlights include a large primary suite with fireplace and sweeping views, a generous eat-in kitchen, multiple living and gathering spaces, and an expansive view deck.

Situated at the end of a private drive, this home features a hillside lot lower level converted into a separate living space with its own kitchen. The two-car garage has also been converted into additional room space.
Tice Valley, located between Rossmoor and Walnut Creek, is a semi-rural and residential Castle Hill neighborhood with rolling hills and equestrian pockets. The neighborhood’s character concentrates along Tice Valley Boulevard near the I-680 overpass, where trailheads, ranch-style driveways, and a low-key roadside rhythm set the tone. Ranch homes and mid-century properties sit behind oaks, with open-space views shaping daily routines. The Iron Horse Regional Trail and nearby Las Trampas ridgelines frame a walk-and-ride lifestyle. Community touchstones include Heather Farm Park, the Lesher Center for the Arts, and the Ruth Bancroft Garden & Nursery. Shopping and dining cluster in Walnut Creek’s downtown grid, while the valley itself stays quiet and green.
