With most, if not all, of Coop Himmelb(l)au's built work, structure plays an extremely important role. With their deconstructivist leanings new structural solutions must be found to achieve the desired end results: post and beam, or similar, structure will not work. In the rooftop office addition an arching spine, held in tension, defines the line of the glassroof construction. The majority of the steel is small members connected, directly or indirectly, to this spine. The effect is both complex and sensual, and is easily one of my favorite structures, even with the questions that arise from their design process.
