The UW Milwaukee Klotsche Center Annex Addition was an education project in Milwaukee, Wisconsin. Completed in 2022, the 17,342 sq. ft. plan had an estimated budget of $5,927,091.

This project constructs a new one-court gymnasium with shell space for future multi-purpose and fitness and strength conditioning areas. It is anticipated that the addition will be located east of the Klotsche Center complex, which is one of the three facades that is surrounded by the conservation and parkland area, Downer Woods. In addition, an enclosed, elevated bridge will be constructed to connect the Pavilion to the annex and allow the underground utilities running through this corridor to remain undisturbed.
