Mercedes Benz of St. Louis

The structural design of this iconic sales and service center creates dramatic spaces and integrates silently with the architecture to accommodate the small site. 

Three walls feature floor to ceiling glass with no visible bracing members, accomplished by cantilevering the roof diaphragm over the showroom from vertical bracing behind the showroom walls. The exposed architectural steel roof framing creates a hi-tech ceiling that adds design value to the theme of the building.

Creative cast-in-place concrete solutions were developed for the service bays and exterior parking structure to provide a practical working facility with efficient interrelationships between operational activities. Service bays are in a structure along the south edge of the site; exterior parking structure along the east.

Renovation of 61,500 SF office/retail building constructed on the foundation of the demolished Union Station Power House.  The $15-million Power House Place project also includes a 44,000 SF building containing a 10-screen movie theater.

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.
