Infrastructure experts CH2MHill called on CORE10 to help them turn this 1970s renovation of a historic 1945 adaptive reuse of three 1920s buildings into a 21st century home for the restored classic trolley cars of the new Loop Trolley system - St. Louis' first active trolleys in fifty years.

In 2011 we explored the abandoned space and documented it's condition for the design team. Over the next two years we led the design process to restructure the working parts of the building and restore the historically significant 1945 art deco facade to NPS standards.

Now the cars are running down Delmar from University to Forest Park and the new HQ will soon welcome visitors to see the trolleys as they are restored and maintained for the next generation.

Renovations included a dramatic structural adaptation by our partners at KPFF and complete mechanical and electrical renovations through a collaboration between CH2MHill and Webb Engineering. The result included a lowered shop floor, raised and restructured shop roof, new tall trolley doors, new roofing, repaired limestone, new historic windows and doors, and a bright new neon sign all in keeping with the 1945 Roberts Chevrolet design.
