Kahler Slater partnered with the State of Wisconsin to restore and rehabilitate the historic State Capitol building. The overall objective was to bring the building into the 21st century in order to be a smoothly functioning seat of state government.

The renovation and restoration included three wings of the Capitol as well as the impressive rotunda. The public spaces, including the vast network of stone corridors, were cleaned and restored, while the private spaces, which include the offices located in the wings, were updated to accommodate the technological requirements of modern lawmakers. Following decades of general use and a number of short-sighted prior remodelings, the restoration process provided an opportunity to remove dropped ceilings and florescent lighting and return to these spaces a look consistent with their original 1917 appearance.

For this project, Kahler Slater worked with Wiss, Janey, Elstner in the development of a Historic Structures Report for the building and in coordination efforts between the interior and exterior restoration process.
