Billie Tsien, in an interview in the latest Hood Quarterly (pdf):

After walking through Wilson Hall, I just can’t wait to clean out everything and take a look at the bones. There are some incredibly beautiful and very powerful spaces in Wilson Hall, and stripping it down will help us to see, for example, the height of the top floor and the skylight. People are really just going to be blown away.
