DETROIT, MI – Dan Gilbert and Bedrock Real Estate Services Tuesday afternoon officially announced the near-simultaneous acquisition and lease of downtown Detroit’s iconic One Detroit Center building. Ally Financial will relocate all 1,500 of its employees to the tallest office tower in the city, occupying 13 floors of the 500 Woodward Avenue building. Ally’s move puts the 43-story, one-million-square-foot building at full occupancy, Quicken Loans Founder Dan Gilbert said Tuesday. It will be renamed “Ally Detroit Center” by next spring. Renderings revealed Tuesday showed the Detroit skyscraper lit purple with Ally’s logo. MORE
