Construction has begun on the foundations for 300 N Michigan, which will rise 523 feet across 47 stories. Addressed as 300 N Michigan Avenue in The Loop, the development will stand at the intersection of N Michigan Avenue and E Wacker Place. Permit filings show that the foundation permits were issued in August, approving the construction of the caissons, foundation structure, and full floor structure up to level four. Full building permits have yet to be filed for the tower portion of the project. 300 N Michigan LLC is the owner behind the applications, an LLC for Magellan Development Group and Sterling Bay, the developers collaborating on this project.
