DETROIT, April 15 (Reuters) - General Motors ( GM ) is

moving its headquarters deeper into downtown Detroit after

spending more than 20 years in its riverfront home at the

Renaissance Center, a person familiar with the matter said on

Monday.

A GM spokesperson could not immediately be reached for

comment, but the U.S. automaker has scheduled a press conference

at 4:30 p.m. EDT (2030 GMT) with CEO Mary Barra and Dan Gilbert,

an owner of property in downtown Detroit. Gilbert also owns the

Cleveland Cavaliers team of the National Basketball Association.

The Michigan automaker will now place its global

headquarters a few blocks away from the so-called RenCen, in a

sleek new high-rise building called Hudson's, which will be the

second-tallest skyscraper in Detroit.

GM remains the only member of the Detroit Three automakers

to have its headquarters in the Motor City. Ford Motor's ( F )

home base is nearby in Dearborn, Michigan, and Chrysler parent

Stellantis has its main North American office in

Auburn Hills, Michigan, about 30 miles (48 km) outside of

Detroit.

Ford is in the process of rehabilitating Michigan Central

Station in downtown Detroit - the city's historic but

dilapidated former rail station - to be a large hub for tech

workers and software engineers.

The GM headquarters - with its glowing logo pasted atop one

of the towers - has become an important part of Detroit's

skyline since the automaker purchased the property in 1996. The

move to this location was "a milestone that helped spark a

downtown renaissance," the company says on its website.

GM and real estate firm Bedrock, which is led by Gilbert,

plan to study how to redevelop GM's Renaissance Center

headquarters, the Associated Press reported earlier on Monday,

citing a person briefed on the plan.

When the automaker allowed remote work during the pandemic,

Barra fielded questions about whether GM would remain on the

riverfront.

The company has since instituted a policy where workers are

asked to come to the office three days per week.

GM also has a technical center in Warren, Michigan, that is

the home base for many of its workers.
