When designers at DC-based Lehman Smith McLeish revamped a run-down former Patent Office building in Crystal City for its new owners, Vornado/Charles E. Smith, their plan incorporated a bonus for commuters who previously went from the below-grade garage to their offices without seeing the light of day.
