Stone, Timber, Steel
This is the vertical-push room. Masonry walls carried buildings until the steel frame, the elevator and the curtain wall let them rise. Here are the riveted column, the joinery bench, a curtain-wall unit and the Monadnock wall section; and the panels that ask why cities go up: land, access, technology, rules, money and people who can build.
