As architect and interior designer Mackintosh's work reflected the latest trends and influences. His early design work from the 1890s was heavily influenced by the prevailing arts and crafts movement but by 1900 his work had confidently embraced the more linear 'art nouveau' style then emanating from mainland Europe. In the years immediately after the First World War and with his career coming to an end, Mackintosh's final works are contrasting yet again only this time they are dominated by bold, geometric forms heralding the arrival of 'art deco'.
