His most important building was St James's Hall between Piccadilly and Regent Street; for almost fifty years it was London's principal concert hall. He was also responsible for two grand shopping emporiums: the Crystal Palace Bazaar and a showroom for Osler's, the glassware manufacturer, both in the West End. These three buildings all opened within a few years of each other, between 1858 and 1860, but had all been demolished by 1926. Their sumptuous polychromed interiors of cast iron, plaster and stained glass were monuments to leisure and consumption.
