The first structure in the development surrounding the new arena is the Milwaukee Bucks training center. The Bucks training center will be a state-of-the-art basketball facility located west of N. Sixth Street between W. Juneau Ave. and W. McKinley Ave. The new facility will serve as the home for Bucks basketball year-round while also allowing for the potential future inclusion of additional commercial space adjacent to the facility.

The new training facility will be two stories high and approximately 55,000 square-feet of space for team use. The facility is designed to be seamlessly weaved into the aesthetic of the entire master plan for the former Park East corridor, including the new arena, entertainment district and surrounding development. The facility will serve as a gateway to the development and a visually-appealing foreground to the city-wide panorama that greets residents and visitors.
