Some of the architects who had emigrated to England found their first clients among other emigrants. Conversions and new buildings of the 1930s are evidence of this close working relationship, which originated in a common experience of exile. Mention may be made of the London houses for the Marx couple (1935–36) and the house of Sigmund Freud (1938), both of which were designed by Ernst L. Freud, but also Fritz A. Ruhemann’s bungalow for the emigrant Leo Neumann (1937–38) or the houses that exiled architects such as Ernö Goldfinger (Willow Road, 1937–39) or Berthold Lubetkin (Hillfield, 1933–35) designed for themselves. This contribution deals with important questions about the history of architecture understood as exile history (and vice versa) by means of some case studies: how homes and therefore also home countries were designed and imagined in a foreign land? What kind of specific ideas and concepts could be realised by close cooperation between the emigrants? Which concepts were imported from the countries of origin; in which way were climate, culture and taste assimilated in material, facade, floor plan and equipment? And finally: to what extent were these houses, built for and by emigrants, representative of particularly innovative attitudes that could help shape the Modern Movement in Britain?
