I liked MIT's "building 20" cluster of wooden shacks, which were featured prominently in the east side of campus. It was said that, when an experiment needed more space, people would casually punch a hole in a wall.

Building 20 was razed to build the Gehry-designed, donor-named Stata Center (incorporating a donor-named Gates "tower"). Breaking with MIT tradition of calling buildings by number, IME most people call it by donor name. (Gehry's reflective surfaces could blind biologists in building 68 across the courtyard, at least before the donor-named Koch building was installed nearby.) Stata has its merits, but I think grad students who punched a hole in the wall would be in trouble.
