San Antonio's Integrated Design-Build General Contractor
Terrapin Construction Group serves San Antonio from 11103 West Ave, Suite 2101, San Antonio, TX 78213 as an integrated commercial general contractor across 38 states. We bring national resources to every South Texas project — from Downtown, the Pearl District, and Southtown to Stone Oak, the Medical Center, the Rim, Port San Antonio, and the I-35/I-10 corridors.
We provide in-house architectural design, structural engineering, MEP engineering, preconstruction, and construction management under one design-build contract. We self-perform IMP installation, PEMB erection, commercial roofing, commercial flooring, and equipment procurement.
San Antonio is Military City USA — home to Joint Base San Antonio (Lackland AFB, Fort Sam Houston, Randolph AFB) and the #2 cybersecurity hub in the country after Washington DC. The military and defense sector drives massive demand for government-adjacent commercial construction, cybersecurity facilities, and defense contractor offices. San Antonio is also a major healthcare market anchored by the South Texas Medical Center (one of the largest medical complexes in the country), Methodist Healthcare, University Health, Baptist Health, and the Brooke Army Medical Center — see our hospital construction boom analysis. Texas's right-to-work labor and no state income tax make SA one of the most affordable major metros for commercial construction at 0.85–0.98x national average.
