AUSTIN TOWERS – Approximately 17 years into its transformation from an Austin airport to a master-planned neighborhood, you might say Mueller is running out of surprises — most of its sprawling 711 acres are now built out on behalf of its master developers at Catellus. We’re excited to see how an expected future apartment project fits around the iconic former Mueller Airport’s preserved control tower, and it was nice to finally see the neighborhood’s first boutique hotel plan a while back — but to us, one of the area’s biggest game-changers lately will be the completion of Parkside at Mueller, the first major condominium development of its kind in the neighborhood by the locals at Pearlstone Partners and New York-based ATCO Properties.
