Company Background
About CG&S Design-Build
CG&S Design-Build began in 1957 as Clarence Guerrero Construction, a family business with Clarence on the tools and his wife Stella running the company, and it later became Clarence Guerrero and Sons. In the 1990s the children took over. Dolores Davis, now owner and general manager, and her husband Stewart Davis, an architect who started the design studio in 1994, turned a remodeling business into a full design-build firm on Corral Lane in South Austin.
The company says licensed architects, in-house interior designers and its own construction crew work side by side, and that estimators price the design as it is drawn, so owners see real numbers before plans are final. Its services page lists renovation, architecture, construction and interior design. Project pages show a pool-side modernist expansion, a Georgetown renovation, a Westover Hills whole-home renovation and a new home in Rosedale.
Google reviews support the pitch. Amy hired CG&S to remodel a kitchen and add a dining area and liked the 3D drawings that showed colors in her own space. Aiden said it was rare to want to hire the general contractor again after an interior apartment remodel and a screened porch that had to survive two designers, material shortages and bad weather. Another reviewer called it a family-owned firm with a design team that is top notch. The website lists AIA, HBA, NKBA, NARI and ASID memberships.
CG&S Design-Build holds 4.8 stars from 58 Google reviews, read October 31, 2026.
Fair concerns: the review count is the lowest on this list, the pages read do not print a licence number or a warranty term, and the firm is set up for design-led projects, so it may not suit a quick single-room job. Hours are weekdays, 7 a.m. to 4 p.m.
It suits owners planning an addition, a whole-home renovation or an older home that needs an architect. It suits less well a small repair. Before booking, ask for the design agreement and construction price in writing, the warranty terms, who pulls the City of Austin permit, and which licensed trades handle electrical, plumbing and HVAC.

Is CG&S Design-Build licensed and what memberships does it list?
CG&S does not print a licence number on the pages we read, and Texas has no state licence for residential general contractors. The company says its architects are licensed, and its website shows AIA, HBA, NKBA, NARI and ASID membership logos. Ask who pulls the City of Austin permit, and check electrical, plumbing and HVAC subcontractors on the Texas Department of Licensing and Regulation (TDLR) lookup.
