The AAMC Headquarters Building features an 11-story main office tower and four historic buildings that are incorporated into the main concrete structure. The exterior features multiple facades, including curtain wall, ribbon and punched windows, and metal and terra-cotta panels.
To preserve the masonry construction of the early 1900s, the exterior along the southeast side of the headquarters incorporates four historic buildings. The preservation effort did not simply include the building facades but also most of the depth of the buildings. Each of the four required structural modifications and restoration work to tie into the new structure.
