Llano Building 1

Llano Building 1 is a new, single-story data center under construction at 10001 Lima Rd in Claude, Armstrong County. The project encompasses approximately 484,954 square feet of primary facility space, developed by GN Dc1 LLC. This substantial build is part of a broader development effort in the region, with the owner of record holding five other TDLR-registered projects in the same area.

The scope of work extends beyond the main data center structure. The filing includes the construction of a new 300-square-foot guard house and a 2,400-square-foot fire pump building. Various mechanical and electrical enclosures are also planned for the site. The estimated cost for this specific building is $292,000,000, which translates to approximately $602 per square foot.

Project Status and Timeline

GN Dc1 LLC registered the project with TDLR in August 2025. Plan review was completed in the same month, and construction was scheduled to begin in August 2025. The filing indicated a completion date of August 2026. However, TDLR has not yet recorded a final inspection, meaning the current state of the site is not confirmed in the public record. Readers should note that the absence of a final inspection does not confirm that the building is occupied or operational.

Architect Orange LLP, doing business as AO, is the design firm of record for this project. The firm has previously worked with GN Dc1 LLC on Llano Building 2, another $292,000,000 project in Claude that also completed plan review. The registered accessibility specialist for this build is Blair Baker. The project is privately funded and located on private land for private use.

In the context of Armstrong County construction, this project is significant. Among 15 TDLR-registered new construction filings in the county, the median estimated cost is $500,000,000. Llano Building 1’s cost is below this median, while its $602 per square foot is close to the county median of $621. The scheduled build window of 364 days aligns with the median for similar projects in the area.
