traditions, focusing chiefly on domestic architecture and employing features such as half-timbering and tile-hanging, whose leading practitioner was Richard Norman Shaw. This development too was shaped by much wider ideological considerations, strongly influenced by William Morris and the Arts and Crafts Movement. While its ethos shared much with the Gothic revival, its preoccupations were less religious and were connected with romantic socialism and a distaste for industrialisation and urban life. On the other hand, British industrial architecture both revived old styles and developed new ones. In the later 19th century vernacular elements mingled with forms drawn from the Renaissance architecture of England and the Low Countries to produce a synthesis dubbed the Queen Anne Style, which in fact bore very little resemblance to the architecture of that reign. While some architects of the period were ideologically committed to a particular manner, a tendency personified by Pugin, others were happy to move between styles. An exemplar of this approach was Alfred Waterhouse, whose works included buildings in Romanesque, Gothic and Renaissance styles and eclectic fusions between them. The new technology of iron and steel frame construction exerted an influence over many forms of building, although its use was often masked by traditional forms. It was highly prominent in two of the new forms of building that characterised Victorian architecture, railway station train sheds and glasshouses. The greatest exponent of the latter was Joseph Paxton, architect of the Crystal Palace. In the 18th century a few English architects had emigrated to the colonies, but as the British Empire became firmly established in the 19th century many architects at the start of their careers made the decision to emigrate, several chose the United States but most went to Canada, Australia or New Zealand, as opportunities arose to meet the growing demand for buildings in these countries. Normally they adopted the style of architecture fashionable when they left England, though by the latter half of the century, improving transport and communications meant that even quite remote parts of the Empire had access to many publications, such as The Builder magazine. This enabled colonial architects to stay abreast of current fashion. Thus the influence of English architecture spread across the world. Several prominent 19th century architects produced designs that were executed by architects in the various colonies. For example, Sir George Gilbert Scott designed Bombay University & William Butterfield designed St Peter's Cathedral, Adelaide. Historical
