100 East Pratt Street

Design/Completion 1991/1992 Baltimore, Maryland IBM Corporation 420,000 square feet Steel and concrete

Stone, precast concrete, metal panel curtain wali

The architectural vocabulary of 100 East Pratt Street is an extension of the modernist context that has evolved along Pratt Street and around the Inner Harbor. Set back from Pratt Street, the envelope maintains the 10-story cornice linę of its neighbors, with the 60-foot wide, 28-story tower connected to the north side of IBM’s existing building. The north facade, facing the downtown area, is realized in stone, masonry, and glass, while the south side features a glass and steel bay window overlooking the harbor.

The tower is crowned by a series of exposed steel trusses that support the projecting south facade. In its delicacy of tensile expression, the truss series evokes the maritime imagery of the waterfront. The trusses also provide the wind bracing reąuired by the very narrow tower profile that allows its northern neighbors uninterrupted views of the Inner Harbor.
