Contra Costa County
Interior Design in Walnut Creek, CA
Our home studio, designing across the East Bay's most established neighborhoods.
Walnut Creek is where New Key Design & Co is based, and it is the city we know most intimately. From our studio on Bancroft Road we work throughout the surrounding hills and valleys, shaping interiors that match the city's blend of polished downtown living and quiet, tree-lined residential streets. Whether the project sits minutes from Broadway Plaza or tucked into the slopes above Rudgear, our team understands how Walnut Creek homes actually live.
Much of the city's housing stock dates from the postwar decades, which means our Walnut Creek work often centers on thoughtful whole-house remodels and additions that open dated floor plans to light, flow, and the warm indoor-outdoor connection the climate invites. We balance durable, family-ready materials with the restrained, tactile palette the studio is known for.
Because we are local, we can be present on site through every phase, coordinate closely with Contra Costa trades and inspectors, and respond quickly when decisions need to be made. For Walnut Creek homeowners, that proximity translates into a calmer, better-managed project.
