6001 Cass is an iconic Albert Kahn building originally designed as Cadillac’s 1920 flagship showroom. It the 1970s it was repurposed as the Wayne State University Criminal Justice Building. The Platform acquired the property in 2018 and converted the historic building to meet the growing demand in New Center.
The heart of the building is the historic second story showroom space, featuring beautiful original vaulted plaster ceilings, wood moulding, and tile detailing. Through integrated design thinking, the renovation incorporates highly-insulated exterior walls and roofs as well as high-performance historically-sensitive replacement windows. The building’s mechanical system features Variable Refrigerant Flow (VRF) technology that maximizes leasable area while reducing energy use by 40% compared to a conventional forced-air system. The building is currently seeking National Landmark status from the National Park Service.
In honor of the building's original architecture, a new vertical blade sign replicates the historic Cadillac LaSalle sign that hung in the same location more than 75 years ago. The 44-foot-tall sign spans four stories and is 21 feet wide. In another nod to the building's 100-year legacy, a timeline of significant Detroit events and milestones lines the building's first floor corridor.
