read as clasps – like those restraining jewels in their settings, holding the
oriel against the main building.
Other sources of inspiration
To conclude this study of expressive and responsive detailing, three
examples are noted where structural details are inspired by sources
from outside the building or its programme. First, the eclectic structural
detailing of the Glasgow School of Art roof structures, where above the
main stair and surrounding exhibition space, decorative timber trusses
evoke images of medieval construction (Fig. 7.33). In another space, a
roof bracket detail indicates a Japanese influence (Fig. 7.34).
At the post-modern Staatsgalerie, Stuttgart, structural details also draw
upon a diverse range of external sources (Figs 7.35 and 7.36). TheSTRUCTURAL DETAILING 149
