GamaBuilt - high-end residential general contractor in San Francisco
GamaBuilt · Established 2005 · San Francisco

A high-end residential general contractor building across San Francisco and Marin.

Founded in 2005 by Edward Gama, GamaBuilt is a design-build firm working at the upper end of Bay Area residential construction. The work concentrates in two veins: renovation and expansion of San Francisco's Victorian, Edwardian, and mid-century housing stock, and ground-up modern construction on hillside parcels and wine-country sites. California licensed and insured, with offices in San Francisco.

Recent work includes 240 Chenery Street and 17 Temple Street, both in San Francisco with MAK Studio; the Buena Vista Avenue East 1910 Edwardian taken down to the studs; Ord Street with Philip Mathews; and the Roosevelt Way residence with Smith & Architects.

Every engagement runs under a single contract. One project manager carries structural, mechanical, millwork, and finish from schematic through punch-list. The homeowner never becomes the integrator.

How GamaBuilt works differently
01 · Accountability

One Team. One Contract.

Most Bay Area contractors subcontract structural, mechanical, electrical, and millwork to separate firms - and the homeowner becomes the integrator. GamaBuilt operates with one project manager and one contract from schematic design through punch-list. Every trade reports through a single accountability line. When something needs to change, the answer comes from one person, not a coordination meeting.

02 · Coordination

We Work With Your Architect, Not Around Them.

GamaBuilt is a builder that speaks design. Edward Gama and the project leads sit in design meetings from schematic onward, flagging constructability, cost, and timeline issues while there is still time to revise the drawings. The result is fewer change orders during construction, fewer surprises, and a finished home that resembles the renderings.

03 · Specificity

Victorians, Edwardians, Hillside Foundations.

The Bay Area's housing stock is unusual: 100-year-old Victorians and Edwardians, post-1989 retrofit requirements, and hillside parcels that don't behave like flat lots. GamaBuilt's portfolio is concentrated in San Francisco, Mill Valley, and the wine country specifically because the firm's expertise is built around these conditions - not generic suburban construction.

From the beginning the design was inspiring but the finished project is even more impressive and has been a dream to live in. For anyone looking for creativity, attention to detail and wonderful execution Eddie Gama should be at the top of your list.

Frequently Asked

About the firm.

What does GamaBuilt build?

GamaBuilt builds high-end residential renovations and ground-up modern construction in San Francisco and Marin. The work concentrates on ground-up constructions of San Francisco's Victorian, Edwardian, and mid-century housing stock, and ground-up modern construction on hillside parcels and wine-country sites.

What is design-build, and why does GamaBuilt work that way?

Design-build is a project delivery model where a single firm holds the contract for both design and construction. At GamaBuilt, that means structural, mechanical, millwork, and finish all report through one project manager from schematic design through final punch-list. The homeowner does not become the integrator between separate firms.

Does GamaBuilt work with outside architects?

Yes. The firm regularly partners with architects of record (MAK Studio, Philip Mathews, and Smith & Architects, among others) and holds the construction contract while the architect leads design. The same single-project-manager coordination applies.

Where does the firm work?

San Francisco and Marin County, with concentrated work in Mill Valley, Glen Park, Buena Vista, and Pacific Heights.

When is the right time to bring GamaBuilt into a project?

Before drawings are finished. The earlier the firm is involved, ideally during early schematic design with the architect, the better the outcome. Bringing the contractor in to flag constructability, cost, and timeline issues while there is still time to revise the drawings is the difference between a smooth project and a series of expensive change orders.
