Bay Area homes,
designed and built
right.
Mars Construction is a licensed design-build general contractor serving the San Francisco Bay Area. We've delivered 300+ bathrooms, 100+ kitchens, additions, and ADUs — drawings to punch-list, one team.
Four things,
done end-to-end.
Mars is design-build — that means architecture, structural, permits, and construction all happen under one roof. No handoffs between firms. No mystery line items. One contract, one point of contact, one team accountable for the result.
Kitchen Remodels
100+ Bay Area kitchens delivered. Open-plan reworks, island additions, full-finish builds — handled from design through punch-list.
Bathroom Remodels
300+ bathrooms completed. Walk-in showers, spa primary baths, tile-and-trim refreshes.
Home Additions
Primary suites, second floors, bump-outs. Architecture, structural, and permits coordinated in-house.
ADUs & Garage Conversions
Detached and attached ADUs across San Francisco, the East Bay, and the Peninsula — design-to-occupancy in one team.
A look at how we build.
Walnut Creek-based, women-owned, and a decade deep in Bay Area remodels — kitchens, baths, additions, and ADUs from drawings through punch-list.
Women-owned.
Built right.
Mars Construction is a women-owned and operated business. We really take the time to understand what you need so we can deliver — and we take pride in providing quality work for every client.
We build kitchens, bathrooms, additions, and ADUs for you to enjoy with your family and friends — and we know how to make beautiful designs functional, so you can use your space to the fullest.
We're not happy until you're happy — simple as that.
The work that earns the next call.
We're a women-owned design-build firm based in Walnut Creek. We've spent the last decade figuring out how to deliver beautifully built homes without the chaos that usually comes with construction — and our clients keep calling back.

Punch List & Warranty
Final walk, every item handled. Warranty on workmanship, and we pick up the phone after the job is done.
The repeat-business test.
The single best signal a contractor is worth their estimate is that homeowners call them back for the next project — and recommend them to the next neighbor. Here's what ours have to say.
We had drywall damage to repair. Maria's team came out a few days later, gave us a fair quote on the spot, and was at our home the next morning to start. They even patched another small section as a courtesy. I'll reach back out when we need more work.
Mars swapped out our old tub for a walk-in shower. Maria met us at the tile shop to help with selections. Professional, on time, and they cleaned up every day. We couldn't be happier with the result.
We hired Mars to renovate a fixer-upper — the whole house. They were right on budget and finished faster than we expected. The team was friendly and paid attention to every detail.
