Adding on top of the old Prentice is intended as a thought exercise in what might be called a third way that may not always get its due in preservation battles...And this is where Ms. Gang comes in, compellingly.

Jeanne Gang and Michael Kimmelman team-up and offer a proposal which could save the concrete, cloverleaf structure from 1975 by Bertrand Goldberg. While Northwestern University argues, it needs new biomedical research facilities, saving Prentice would be too costly and/or difficult, preservationists have been trying to save the building from demolition. However, Gang and Kimmelman have a simple solution "Build a research tower on top of Prentice".
