DETROIT—Southfield-based Plante Moran, a certified public accounting and business advisory firm, said Thursday that it plans to lease 15,000 sq. ft. at the Compuware building in a downtown expansion.

The company would open its seventh regional office on the third floor of the building with about 75 employees. Gordon Krater, managing partner at the firm, said the company has seen 10 percent growth in the past 15 months, and is already spending more time downtown working with public and private sector organizations.

“It just makes sense to open our next office in downtown Detroit,” he said in a statement. “It will also help us better attract professionals who want to be part of the urban work environment as we continue to expand our team. There is an excitement and vitality about the city. Good things are happening, and we are proud to be a part of it.”

Plante Moran CRESA, a fully integrated independent real estate firm affiliated with Plante Moran, brokered the lease deal between Plante Moran and Compuware. The company did not comment further on the lease terms.
