General Motors Co. and Dan Gilbert's Bedrock LLC are planning to tear down two of the automaker's five Renaissance Center towers as part of a reimagining of the long-struggling complex the automaker is vacating next year in a major realignment of the city’s business and commercial real estate landscape.

General Motors and real estate firm Bedrock announced on Monday a development plan that would permanently alter the Renaissance Center.

Two towers at Detroit’s iconic Renaissance Center would be razed and the complex converted to a mix of housing and offices under an ambitious $1.6 billion plan announced on Monday

The plan would reduce office space and redevelop the remaining three towers into hospitality and housing - leaving most of the skyline intact, while adding a large public space on the riverfront.
