In May, Keystone Construction completed the next phase of development at The District of St. Louis with the Hub Stl, a $4 million state-of-the-art outdoor entertainment space in Chesterfield at Boones Crossing.

Construction of the live outdoor music venue began in Fall 2022. Keystone built a 70-foot by 21-foot elevated performance stage with a synthetic turf viewing area to hold up to 400 people.

Keystone previously built two other anchor destinations within The District: Main Event and The Factory. Main Event is a 50,000-square-foot indoor entertainment center and The Factory is a 52,000-square-foot indoor concert venue which is the first performance venue to be constructed from the ground up in the Midwest in more than 20 years.
