Just three months ago the Texas Retirement System (TRS) sold its concrete Austin offices for over $100 million. And in a few months, TRS workers will be ready to move into their new home.

Construction is complete on the first phase of an office district at Mueller, the master-planned development in Austin. Dubbed Mueller Alpha, the building inaugurates a three-phase, 800,000-square-foot campus.

Located at 1900 Aldrich St., Mueller Alpha rises six stories and comprises 210,428 square feet. The Teacher Retirement System of Texas (TRS) will occupy the second through sixth floors as part of its relocated headquarters.

In December 2021, TRS acquired the property from the developer, Shorenstein Properties. At the time of the acquisition, TRS said that it planned to begin moving personnel to Mueller Alpha in the spring of 2023. Mueller Alpha’s amenities include outdoor seating, meeting areas, an outdoor amphitheater and open-air courtyard.

An eight-level parking garage, including two underground levels, is connected to the building via the open-air courtyard and accommodates about 1,000 vehicles. Cadence McShane was the major contractor.
