General Motors began moving its global headquarters into Hudson's Detroit on January 12, 2026, ending a roughly three-decade run inside the Renaissance Center. The decision was first announced on April 15, 2024, three days after Hudson's Tower topped out across town on Woodward. GM is the signature tenant in the 12-story Block Building, the shorter of the two towers in the Hudson's Detroit complex Bedrock developed.
The company first leased the top two floors. By November 2024 that had grown to four floors. A color-changing GM logo was installed on all four sides of the building's roof in October 2025.
The main lobby is named Entrance One, after the historic employee entrance at the original GM headquarters. The Renaissance Center has been emptying out for over a year. By November 2025, only 18 office and retail tenants remained in a complex with 5.55 million square feet.
Burger King, the last food court tenant, closed November 26. Panera had closed in October. Joe Muer Seafood and Andiamo Detroit Riverfront, both in Tower 400, will have to relocate ahead of demolition.
The U.S. Post Office at the RenCen was reported to close on January 20, 2026. GM closed the public spaces on January 12 with no public announcement. What comes next is a $1.6 billion redevelopment by Bedrock and GM.
The plan: demolish Towers 300 and 400 and the glass-enclosed retail podium, opening about six acres of riverfront to public access. The central 73-story tower stays as a Marriott but cuts its room count from roughly 1,300 to 850, with the upper floors converted to apartments. Tower 100 becomes residential.
Tower 200 keeps offices. Bedrock has committed about $1 billion. GM has pledged $250 million.
Bedrock is seeking at least $250 million in public support, including a $75 million package already approved by the Downtown Development Authority. Demolition is planned for April 2027, after Detroit hosts the NCAA Men's Final Four. The complex was conceived by Henry Ford II in 1971 and opened in 1977.
GM bought the majority of it in the mid-1990s. For three decades, the GM logo was the dominant Detroit skyline feature from the riverfront. As of April 2026, the logo is gone.
A Marriott sign rotates in its place.
