Bay Area design-build

Designed by an architect. Built by our own team.

Remodels, additions, ADUs and new homes. We draw the plans, handle the permits and build it, so you have one team from the first sketch to move-in.

    Design, permits and construction

    Hire us for the whole project or just the design. Every build is run by our licensed contractor, and every design is drawn by our architect.

    Remodels

    Kitchens, baths and whole homes

    Most Bay Area homes were built before 1970. We update layouts, systems and finishes, with structural, electrical and plumbing work handled by licensed trades.

    • Kitchen and bathroom remodels
    • Whole-home renovations
    • Layout changes and wall removal

    Additions

    Room additions and second stories

    Add a bedroom, a primary suite or a full second floor. We design it to match your house, take it through permits and build it.

    • Ground-floor additions
    • Second-story additions
    • Garage conversions

    ADUs

    Accessory dwelling units

    California now allows ADUs on single-family lots. They're one of the best ways to add rental income or room for family. We handle feasibility, design, permits and construction.

    • Detached backyard ADUs
    • Attached ADUs
    • Junior ADUs inside the house

    Our work

    Before, during and after photos of projects we've designed and built.

    Process

    From first call to move-in

    Because design and construction happen in one company, your plans are priced and buildable before you sign a construction contract.

      Common questions

      How long does a permit take?

      It depends on the city and the project. We'll give you an estimated timeline for your city during design.

      Do I have to use you for construction if you do my design?

      No. You can hire us for design and permit drawings only, and take them to any licensed contractor.

      Are you licensed and insured?

      Yes. Our California contractor license is CSLB # 1131578. You can check it at cslb.ca.gov.

      What size projects do you take?

      From a single bathroom to a new home. Tell us about your project and we'll let you know if it's a good fit.
