The Trocadero in London's Piccadilly was first to feature an external curved canopy in Kalwall. A variation on this are the low-pitched canopies (pictured) on a new hospital in the north of England, designed using Kalwall because of its low weight, low maintenance and relative opaqueness to dirt when viewed from below.
