Tilton, Kelly + Bell is currently designing a renovation and restoration for the historic Illinois State Armory building, working for the Illinois Capitol Development Board and with Central Management Services.  The Armory is a 1930’s WPA building in Springfield, Illinois, prominently facing the Illinois State Capitol building.  Planning will be coordinated with the Capital Complex Master Plan, concurrently under development; the State Historical Preservation Office will review preservation efforts.

Vacant for approximately ten years, the Armory presents a deteriorated condition, with considerable water damage from the roof affecting both the interior and the façade, and with outdated systems and condition throughout. The historic multi-story drill hall will be partially restored in a modified version, creating a dramatic core for the building’s future accommodation of 800 state workers.  The original building contained 90,000 square feet of offices in separate vertical towers; current plans will add 96,000 square feet of office space by incorporating a portion of the drill hall volume.  New offices will increase efficiency per state guidelines.

The project work includes a new roof, new skylights, a restored limestone façade, interior and exterior accessibility modifications, and a new circulation pattern and core location.  Comprehensive code and condition updates are required to the architecture and MEP systems throughout, with the goal of providing flexible, functional, and aesthetically pleasing office space to meet current and future needs.
