STRUCTURAL DETAILING 161▲ 7.62 Centre for Understanding the Environment (CUE), Horniman Museum, London,England, Architype, 1997. Front façade with chimney-columns.▲ 7.63Interior column and beam.Environment (CUE), London, is a consequence of its ecologically sustainabledesign, rather than any other reason. Primary structural membersare hollow, exemplifying the highest possible level of structure andservices integration (Figs 7.62 and 7.63). 16 Structural members functionas air conduits in this naturally ventilated building. Column and beamcross-sections are therefore larger than expected for a building essentiallyof domestic scale, even accounting for the weight of its turf roof.Warm air is extracted through circular penetrations in the triangularcross-section plywood web-beams, and channelled horizontally tocolumns. Columns that terminate above roof height as chimneys, moveair vertically. For such a relatively small building the structural membersappear heavy.Plain to decorativeLaVine describes the exterior ground floor columns of the iconic VillaSavoye, Paris (Figs 7.64 and 7.65), as ‘classically placed but unadorned,slender cylinders, reflecting a technological stance of the twentieth century’.17 Consistent with the plainness of the columns, the floor beamsare rectangular in both cross-section and elevation. Their widths thatequal the diameters of the columns and result in tidy beam–columnjunctions, are evidence of attention to detailing that does not seekattention.A more recent building illustrates the potential for structural detailingwith decorative qualities to enhance architecture.
