The development will feature 425,000 square feet of residential space, 240,000 square feet of office space, 120,000 square feet of event space, and 100,000 square feet of retail space.
There will be at least 700 underground parking spaces, according to Detroit News.
Quicken Loans founder Dan Gilbert launched Bedrock in 2010, three years before the city would file for bankruptcy.
Gilbert-owned businesses employ about 17,000 people in downtown Detroit today.
Late last year, Gilbert dismissed criticism that his redevelopment efforts are examples of "corporate welfare."
