Home Additions & ADUs
East Bay & Beyond
New square footage that looks original — plus ADUs that earn rent or house family. Based in Brentwood and serving a 60-mile radius across Contra Costa, Alameda, San Joaquin, Solano and Napa counties.
A good addition reads as if it was always there — the rooflines continue, the windows match, the proportions hold. We design and build primary-suite additions, kitchen expansions, family rooms and second-story pop-ups that blend into the original house instead of announcing themselves.
Accessory dwelling units are the best investment in California residential construction right now: rental income, space for family, long-term property value. We handle feasibility, the state's evolving ADU rules, local permitting and utilities through final inspection.
