The new owners of 100 Madison Street, formerly AXA Towers, engaged Holmes▪King▪Kallquist & Associates to reinvigorate the lobbies of the twin office towers built in 1962 and 1968. Brown carpet and rust granite tile were stripped away, and the original, bright terrazzo floors and travertine marble walls were restored. New granite concierge desks were added to each lobby, and new lighting installed. A new promenade connecting the two tower lobbies was created through the lower “link” building. This 200-foot-long public space allows an interior connection between all of the building lobbies and opens up previously inaccessible leasable area. This space utilizes a coffered barrel vault to reduce its apparent distance, and uses terrazzo tile floors and bronze finish column covers to unify the new space with the restored lobbies. A new conference area and toilet rooms were also added for tenant use.
