We’re thrilled to share that our St. Louis office – the Power House – has been selected by mySTL as one of the coolest workspaces in the city. As mySTL indicates, “there are plenty of impressive businesses that call St. Louis home, but some make an especially bold statement with their workspaces that simply can’t be overlooked.” It’s been 10 years since our team rejuvenated the historic landmark and moved in to call it home.

After standing vacant for nearly 30 years, the 19,000 sf Power House building in downtown St. Louis opened as CannonDesign’s St. Louis office. Constructed in 1928 and designated as a landmark by the National Historic Register, the Power House provided coal-fired steam heat to a dozen downtown buildings until its decommissioning in 1980.

Although the building’s exterior shell and original structural steel were fundamentally sound, significant imagination and rigorous design analysis were required to convert the building for workplace use. New floors were cantilevered within the building’s massive volume to create a total of 32,000 sf of office and conference space. The floors are set back from the building’s spectacular windows to maintain the sense of transparency and volume. Exterior improvements included creation of a 3,500 sf urban garden and historically accurate replacement of windows in their original masonry openings.
