Contra Costa County

Interior Design in Pleasant Hill, CA

Mid-century homes opened up, warmed up, and brought up to date.

Pleasant Hill sits at the heart of central Contra Costa, an established, walkable city with a deep stock of mid-century homes ready for a thoughtful second act. Our work here is often about transformation, taking compartmentalized 1950s and 60s plans and opening them into bright, connected spaces that suit how people live now.

In neighborhoods like Gregory Gardens and Poets Corner, we modernize kitchens and baths, add square footage where it counts, and rework circulation so homes feel larger without losing their scale. The studio's restrained material palette brings a sense of calm luxury to houses that were never originally built for it.

Pleasant Hill rewards smart, value-driven design, and we approach each project with an eye on both the everyday experience and the long-term worth of the home.
