STRUCTURAL DETAILING 151AESTHETIC QUALITIES OF DETAILINGIntroductionThis section explores and illustrates the enormous diversity of the aestheticqualities of structural detailing. Pairs of contrasting qualities arecategorized into four broad groupings. The process of categorization isimprecise since some details can be discussed in the context of anothergrouping. But the purpose is not to pigeon-hole a detail aesthetically,but rather to illustrate the amazing variety of different structural languagesand approaches to structural detailing. Each detail invites its ownarchitectural reading and influences how building users perceive andexperience the architecture of which it is part.Refined to utilitarianAlthough one might expect refined structural detailing in all works ofarchitecture, this certainly is not the case. Sometimes the budget ortime constraints frustrate opportunities for refinement. Perhaps toensure consistency with an architectural concept that for examplerequires a raw industrial aesthetic, refinement is avoided deliberately.Refined structural details are frequently described by such terms aspure and elegant. Any extraneous material and componentry has beenedited away. One is left with the impression that the detail cannot beimproved upon. It has undergone an extensive process of reworkingthat has left the designer satisfied with the outcome – the technical andaesthetic requirements resolved in a synthesis of structural necessityand artistic sensibility.Beginning with two examples of refined detailing, readers will recall thatthe expression of architectural quality on the exterior of BrackenHouse, London, has already been discussed and some of its exposeddetails noted (see Figs 4.40 and 4.41). The building’s exterior providesother examples of refined detailing, such as on the main entrance trussthat supports a translucent canopy (Figs 7.39 and 7.40). Metal bossesarticulate the joints between the bottom-chord members and the othersthat are inclined. The spoke-like diagonals, ribbed and tapered to matchthe structural dimensions at each end, possess the same visual qualitiesas elegant mechanical or aeronautical engineering components.A similar high degree of structural detailing refinement is evident atQueen’s Building, Cambridge (Fig. 7.41). In describing it, a reviewerobserves: ‘One would say that the building was a montage of Hopkinsmotifs, were it not such a unified, monolithic form – more like a beautifullycrafted piece of furniture than a building.’ 13 The composite timberand stainless-steel theatre roof trusses incorporate refined structural

Precisely located bolts pass through stainless-steelplates inserted between timber members. Rods elegantly connect toand fan out from a plate at a truss apex. The building exterior also featuresnotable exposed structural detailing. Small stainless-steel ringnodesdenote the anchorages of an innovative post-tensioning system
