Dan Gilbert has purchased two more buildings along Woodward Avenue in downtown Detroit.

Gilbert, the founder and chairman of Quicken Loans Inc. and Rock Ventures LLC, bought the Grinnell Building and the Sanders Building just north of Clifford Street, a spokeswoman for his Bedrock Real Estate Services LLC confirmed. dBusiness first reported the news Friday.

The seller was Farmington Hills-based Howard Schwartz Commercial Real Estate LLC.

The purchase price was not disclosed.

According to CoStar Group Inc., a Washington, D.C.-based real estate information service, the Grinnell Building has 43,000 square feet. It is currently home to the Henry Ford Health System QuickCare medical clinic, which opened last summer.

The Sanders Building is just north of there at 1525 Woodward with 40,000 square feet.

The two properties on the west side of Woodward are two blocks north of the 2-acre site of the former J.L. Hudson's department store.

A Dan Gilbert-affiliated entity recently received approval from the Downtown Development Authority of an amended development agreement that includes the purchase of a below-ground parking garage on the site as well as amended timelines for the development, the majority of which is expected to be constructed by April 2020.

On the 1500 block of Woodward, Gilbert also owns the buildings at 1505 Woodward, 1520 Woodward, 1528 Woodward and 1550 Woodward.

He owns more than 14 million square feet of space spread across 80 properties like buildings and parking decks, largely in and around downtown.
