The complete renovation of a 40-year-old library designed by renowned brutalist architect Marcel Breuer required a major structural renovation throughout the 10-story building to allow the facility to function as a modern library. For this renovation, the project team added a smoke atrium throughout the middle of the building, transformed two floors into a single, two-story event center, installed a large skylight and drastically increased the number of windows. The effect of these elements was to transform the library’s original dark brutalist interior into a bright, inviting space.

Creating the new two-story event center from portions of the fifth and sixth floors required a complex structural engineering design. Building load paths needed to be changed, which resulted in structural steel members throughout the building being upsized, reinforced and braced. Additionally, two of the project’s largest structural beams were added to span the two-story space and create a new roof structure.
