Crosby Hall, the heart of the School of Architecture and Planning's studio-based experience, is undergoing a historic renovation.

The exterior of Crosby Hall, a 1931 Georgian Revival design by E.B. Green & Sons, will be fully restored — stone, slate roofs and all.

The arched ceiling is retained; the skylights are part of the renovation.

Corridors will serve as flexible spaces for critiques and displays of student work.

With no load-bearing walls, Crosby will be transformed into a series of open partitions and space.

The entrance with its vaulted ceiling will be preserved.

A panoramic view of the space on the second floor. The classical exterior obscures the internal reality of a modern, steel-frame building with poured concrete floors.

Third-floor windows and space. The design includes the historically sensitive replacement of windows and doors, including restoration of unique windows in the attic. All of the work will bring the building back to its original grandeur.
