One Campus Martius

One Campus Martius is a building located in downtown Detroit, Michigan. It began construction in 2000 and was finished in 2003. It has seventeen floors in total, fifteen above-ground, and two below-ground, and has 1088000 sqft of office space. The high-rise was built as an office building with a restaurant, retail units, space for Compuware and a fitness center, as well as an atrium. The building now has Rocket Mortgage, Microsoft, Meridian Health, Plante Moran and Compuware as its major tenants.

The building was constructed in the late-modernist architectural style, using glass, granite and limestone as its main materials. AIA Detroit's Urban Priorities Committee rated the building's entry as one of the top ten Detroit interiors.

History
The building sits on the Kern Block which was once home to the Kern Department store. The store had existed in some form or another on this site since 1900. The last incarnation of the store was demolished in 1966, and the area remained greenspace until 1999 when Campus Martius Park began to take shape. Compuware moved its headquarters and 4,000 employees to a newly constructed building on the site in 2003. Quicken Loans agreed to a five-year lease agreement to move its headquarters and 1,700 employees to the building in 2010. Plante Moran followed suit with a lease agreement in 2013, deciding to move 75 employees to the building.

In 2006, a banner commemorating the Stanley Cup victory of the Carolina Hurricanes, owned by Compuware CEO Peter Karmanos, was raised on the building's exterior.

Compuware's presence in the building has lessened as it has downsized during the 2010s, and the company now has around 800 employees in the building. The building was sold in a joint venture to Dan Gilbert's real estate group Bedrock Real Estate and Meridian Health for $142 Million in November 2014. As part of the deal Quicken Loans took an additional floor bringing its space in the building to 300,000 sq. ft. Meridian moved 700 team members into the building in spring 2015 with 1700 employees expected by the end of the year. Compuware's remaining employees will stay in the building.

There has been some construction in the late 2010s to fill in the missing "wedge" at the north of the building, expanding it by over 300000 sqft.
