Why Castroville Is Building
The Little Alsace of Texas is adding an 83-acre mixed-use development at US 90 and FM 471. GRAMS builds retail, medical, and metal building projects that honor a historic town while serving a growing one.
Castroville was founded by Henri Castro and settled by Alsatian farmers whose European architecture still defines the town, with roughly 97 historic buildings on its walking tour and a National Register historic district. That heritage is now meeting real growth: the US 90 and FM 471 intersection carries about 44,000 vehicles a day, and Alsatian Oaks, an 83-acre master-planned development with more than 80 acres of commercial land and 1,000-plus homes, delivered its first retail phase in spring 2026.
Medina Valley ISD, Bill Miller BBQ, Walmart, AC Technical Services, Zinsmeyer Mechanical and Welding, and two auto dealerships anchor local employment, and Texas Research Park, a one-million-square-foot Microsoft data center, and GM Financial's operations center sit just seven miles east.
GRAMS builds for both sides of Castroville: contemporary retail and medical space along US 90 and careful work near the historic district, where materials and massing matter. Metal building systems, engineered concrete, and clean finish-outs are our core, and Castroville is a straightforward drive west from our San Antonio headquarters.

How We Work In Castroville
Every market has its own permitting path, its own logistics, and its own pace. We plan for Castroville's before the first estimate goes out.
Permitting & Codes
Castroville's Community Development Department coordinates permitting, building code enforcement, zoning review, and historic preservation. Commercial permit packages are submitted by email to the department, and projects in or near the historic district carry additional design review. We prepare complete packages up front so review moves in one pass.
Site Logistics
US 90 is a heavy truck route and FM 471 carries commuter traffic to San Antonio, so delivery timing and turn access matter. Our logistics plans define ingress, laydown, and crane positions that keep frontage traffic moving and protect adjacent historic structures from vibration and dust.
Market Awareness
We track Alsatian Oaks and the US 90 corridor because they are producing pad sites, shell buildings, and finish-outs for the first time in Castroville's modern history. Our team also understands that historic preservation is part of how this community defines quality, and we plan for it rather than around it.
