Exhibition centre

An exhibition hall whose structure is the whole building. A row of raking white fins stands clear of the glass and carries a canopy that cantilevers well past them; the wall behind is glazed from ground to roof and braced with diagonal ties, so the fins take the load and the wall takes only the weather. The result is a long, low front with deep shade at the entrances and no solid elevation anywhere along it — which is the point for a hall whose contents change every month.
