The building incorporates the Garden Plaza, a part of a through-block arcade connecting 56th and 57th Streets and the IBM with the neighbouring Trump Tower. The spacious, 930 m2 greenhouse-like glass atrium has a zig-zag roof of alternating diagonal and vertical panes, and it houses full-sized bamboo trees within, although many of the original number of eleven have been removed to accommodate contemporary art installations by the Pace Wildenstein Gallery.

The building also originally had the IBM Gallery of Arts & Sciences, a museum and art performance and exhibition room next to the lobby, but the gallery was later closed. The space has been occupied by Freedom Forum's media museum Newseum. Although IBM sold the building to the developer Edward J. Minskoff and Teachers Retirement System of Ohio in 1994, it has retained a sizable portion of the building in its use. In Feb. 2003, the company renewed the tenantship deal to continue after 2004 -- the company will remain on eight floors of the building.
