Power House Place was built on top of a 4-foot high bolster beam constructed on top of the original Power House foundation, and was designed to complement the adjacent St. Louis Union Station redevelopment.  The Power House’s 200-foot-high smokestack, which rests on a square brick base, was retained to serve as the development’s focal point.  The area beneath the stack is part of the building’s leased space.

EDM also provided structural engineering services for the terminal itself, which saw its last train in 1978, and reopened in late 1985 as St. Louis Union Station – an 825,000 SF complex which includes approximately 115 retail businesses and a hotel.
