CannonDesign’s St. Louis Office Celebrates 10 Years in Historic Power House

In 2006, CannonDesign saw a rare opportunity for its St. Louis office in one of the city’s signature buildings: a vacant steam-heat power plant built in 1928 as part of the city’s post-World’s Fair economic re-development efforts.

Ten years later, after a major redesign and adaptive re-use process that gutted its interior and created a new-meets-old design concept, the Power House is still generating positive energy for its occupants — our St. Louis headquarters — its neighborhood, and its city. We celebrate its first decade with a look back at its history and impact.

When built, the Power House powered a dozen downtown city buildings, including City Hall, the Kiel Opera House, and multiple municipal buildings and courthouses. Its coal-burning mechanics were visible to the public through the glorious 26-foot-tall arched windows. A significant building for residents, the Power House was a flagship of great civic initiative and a pillar of municipal pride.

But in 1980, after more than a half-century in operation, the plant was decommissioned. Falling sharply into disrepair, its beautiful brick facade became an eyesore; its roof infamously sprouted trees — an ironic last hope for life on this blighted neighborhood cornerstone. A landmark on the National Register of Historic Places, the Power House needed new fuel.

It sat vacant for some 25 years, until CannonDesign purchased it as a new home for our St. Louis regional office. The team quickly realized its potential as a truly unique office environment, and as an emblem of the neighborhood’s rebirth.

Under the project leadership of principal Thomas Bergmann and design leadership of David Polzin, the new design that emerged reflected CannonDesign’s ideals of creativity, collaboration and sustainable design.

“We wanted the office to be demonstrative of our values. We wanted to inject the work environment with an atmosphere that would stimulate design exploration; we created multiple soft spaces for teams to come together to collaborate, and we pursued LEED Gold certification, working with our engineers to understand building performance,” says David.

The challenge was a small building footprint, but a large volume of space. The immense interior was gutted to its brick shell, maintaining the only massive steel plate columns. A whole new interior was injected into the brick shell, calling for “ship-in-a-bottle”-precision construction methods.

All-new HVAC, plumbing and electrical infrastructure were added; concrete foundations were exposed as walls for conference rooms; and two new floor plates were added above the ground floor to make use of the building’s dramatic height. By holding the new floors away from the exterior walls, all employees benefit from access to significant daylight and beautiful beautiful panoramic views of the neighboorhood.

The new design was an immediate success for CannonDesign’s 100-employee St. Louis team, as David explains: “The most gratifying part about the building has been the joy of seeing it used as it was intended … it has been transformative for our design culture.”

It also signaled a new day for its community. Since opening, the office has renewed the area’s interest in adaptive re-use of its historical structures, and has inspired a new generation of similar projects throughout the design-build landscape.

For CannonDesign, the project has garnered us with multiple international awards, including the AIA Institute Honor Award, the SARA Distinguished Building of the Year, and the ARIDO Project of the year, among others.

But beyond awards and recognition sits the nearly century-old truth of the great Power House — that in generating and distributing power to a city, even a hallmark building is more than its beams and bricks. When it becomes a city’s hub of energy, growth and later rebirth, it becomes the very cornerstone of its identity.

That the company’s vision in 2006 paid off is an enormous feather in our cap, to be sure. But that it did so in honor of the city’s legacy of design, industry and midwestern sense of community, is an even bigger reward.

Happy new 10th birthday, Power House! A toast from your CannonDesign family, working hard to fuel your next 90 years!
