On the Burroughs Wellcome Building
"This complex climbs up and down a beautiful ridge in the green hills of North Carolina and is architecturally an extension of its site. An "A frame" allows the greatest volume to be housed on the lower floors and yet connected to the smaller mechanical system at the apex of the building. The diagonal movement of interior space opens up magnificent opportunities. Anticipation of growth and change is implicit in the concept."
