AT&T Caldwell Lane in Del Valle, TX

The Caldwell Lane Building is a new construction project in Del Valle, Texas, featuring a storage warehouse with 8,006 square feet of floor space. The facility includes office space, a work room, and restrooms, all located at 3940 Caldwell Lane in Travis County. This privately funded development is owned by AT&T, which is listed as the developer of record for the site.

AT&T engaged PBK as the design firm of record for this project. The construction scope involves a pemb building storage warehouse, a specific type of modular construction that allows for rapid assembly. The estimated cost for the entire build is $750,000, which calculates to $94 per square foot. This figure is below the county median of $125 per square foot for similar new construction filings in Travis County.

The project timeline was compressed compared to regional averages. The scheduled build window was 122 days, which is shorter than the county median of 304 days for new construction projects. TDLR completed the plan review in March 2025, and construction was scheduled to begin in June 2025. The filing indicated a completion date of October 2025.

Current Status and Record

While the initial plan review is marked as complete, TDLR has not yet recorded a final inspection for this project. Consequently, the current state of the site is not confirmed in the public record. The project remains registered with the Texas Department of Licensing and Regulation (TDLR) under the accessibility specialist Mark S Robinson. This registration ensures the facility meets state accessibility standards during its construction phase.

AT&T has a history of similar projects in the region, with six other TDLR-registered projects totaling $36,924,352. These include facilities in Dallas and Austin, such as the Spectrum Lab and various tower structures. PBK, the design firm, has also worked on large-scale projects like the Saddleback Elementary School in Liberty Hill. The Caldwell Lane Building fits within a broader pattern of commercial and utility infrastructure development in the Del Valle area.

The surrounding area, ZIP code 78617, has a population of about 28,932 people according to U.S. Census estimates. The median household income in this area is $78,019. Local businesses such as Cool Horizons, a general contractor, operate near the site. The project contributes to the local construction activity in Travis County, where the unemployment rate was 3.9 percent in August 2026.
