Interior Remodel Secure Floor in Austin, TX

The AUS16 Building at 11815 Alterra Parkway in Austin recently completed a minor interior alteration on its 11th floor. This renovation, filed under the name Interior Remodel Secure Floor, involved the relocation of a wall and the installation of a secure door. The project was registered with TDLR in January 2025, and the authority closed the project file in the same month, marking the end of the accessibility review process for this construction.

The work was executed by TR Domain 10 LLC, which also holds the record for the nearby Domain 10 development. Cushing Terrell served as the design firm of record for this specific alteration. The scope was limited to 150 square feet of existing space, with an estimated cost of $70,000. This results in a cost per square foot of $467, a figure that sits above the Travis County median of $104 for similar renovation and alteration filings.

The scheduled build window was 32 days, which is shorter than the county median of 98 days for comparable projects. Construction began in February 2025, with a completion date listed for March 2025 on the original filing.
