DETROIT (AP) — General Motors and real estate firm Bedrock will jointly study how to redevelop the automaker’s huge headquarters tower complex in downtown Detroit, a person briefed on the plans said.

GM CEO Mary Barra and and Bedrock Chairman Dan Gilbert plan to hold a news conference Monday afternoon to discuss the deal involving the Renaissance Center, said the person, who asked not to be identified because the plans have not been formally announced.

The person says the plan does not involve a sale of the complex, which is an icon in Detroit’s skyline and often appears on sports television broadcasts.

Gilbert’s company has been buying up properties downtown for many years. He also runs loan company Rocket Mortgage.

In a 2022 interview, Barra told The Associated Press that GM will keep its main office in the seven-building tower complex just across the Detroit River from Canada.
