ADU Design in Houston, TX
Houston is driven by the Energy Corridor and the Texas Medical Center, the largest medical complex in the world, plus the Port of Houston and a dense petrochemical industrial base along the Ship Channel. Gulf Coast humidity, hurricane exposure, flat bayou terrain, and famously no zoning ordinance shape every project.
