72 STRUCTURE AS ARCHITECTURE▲ 4.35 Fitzwilliam College Chapel, Cambridge, England, Richard MacCormac, 1991.A chapel side-wall with an accommodation block to the left.walls, equally likely to be read as non-load-bearing cladding as structure,contrast with the explicitly exposed structure at the Licorne stadium,Amiens, that similarly engenders perceptions of protection and enclosure(see Fig. 3.13).The exterior structure of the Öhringen Business School representsthe antithesis of the symmetry and calmness of the Fitzwilliam CollegeChapel. Outside the main entrance the exterior structure breaks longestablished traditions of structural order and rationality (Fig. 4.36). Infront of a glazed wall, three cross-braced buttresses appear to be quitehaphazardly orientated – their alignment neither relating to the buildingenvelope nor to the interior structure. A similarly unusual relationshipexists between the buttresses and the thin steel girts they support.The normal hierarchy of mullions supported by girts that are in turnsupported by buttresses is subverted. A girt passes through a buttresswithout being able to transfer its loads to it (Fig. 4.37).Exterior structure in this area of the school appears ad hoc and crude.Blundell-Jones notes that this aesthetic is in fact carefully developed anda ‘confident use of a vocabulary elaborated over decades’. 9 The architect,Behnisch, is well known for his colliding geometries, layered spacesand careening volumes. Upon entering the atrium, a fragmented andlayered structural language contributes to a light and lively, if not exciting,interior space.
