Looking at the end elevation of the aluminum box building type. These house the aluminum sculptures. Judd, and the architect he worked with took the flat roof buildings, and capped them (leaving the existing roof on) with the 'quonset hut' - corrugated metal barrel vaults. Note the polycarbonate (also corrugated) up on the upper facade, presumably letting light in, though I saw no direct access. The space up there is huge - I don't know what's going on up there, but it must be a great room to be in when the rainstorms hit!
Also interesting is the bond beam added to the top of the existing structure and the 'tooth' sticking up out of the corrugated polycarbonate panel, almost making it look like a 'slot tab a in to space b' type of construction.
