Dan Gilbert has purchased another building in Detroit near the hub of his other holdings.

Bedrock Real Estate Services LLC, the development arm of Gilbert's real estate empire, closed earlier this month on the purchase of the eight-story retail/office building at 1400 Woodward Ave., located at the intersection of Woodward and Grand River Avenue, according to two real estate sources.

How much the building sold for is not known.

Currently housing the Eastern Wig & Hair Co., the 60,000-square-foot building was constructed in 1925, according to Washington, D.C.-based real estate information service CoStar Group Inc.

According to Crain's "Who Owns Downtown?" database published in August, the building is owned by Sue Lee. Reached by phone last week, she said the building had not yet sold.

The building at 1400 Woodward is located on one of the downtown blocks that Gilbert, the founder and chairman of Rock Ventures LLC and Quicken Loans Inc., plans to transform with "core urban shopping," such as home retail, fashion and restaurants with his place-making plan.

A Detroit Historic Designation Advisory Board report posted on the city's website says that 1400 Woodward was constructed as the T. B. Rayl & Co. store, which sold sleds, ice skates, mantle pieces, tool chests and cutlery.

The Eastern Wig website says it has been in business since 1971. The advisory board report says Eastern Wig has been open on only the first floor of the building since 1997.

The purchase brings the size of Gilbert's real estate portfolio to more than 40 buildings, all of which were bought in the last three years.

The Detroit office of Colliers International Inc. represented the seller. Bedrock represented itself in the deal.
