How can Nordic modernism be defined? Did German city planners look to the North for inspiration after the Second World War? In what way did the social model affect architecture and city planning in the Nordic countries? What specific features characterise architecture and town planning in the Nordic countries compared with post-war Germany? The 50th anniversary of Interbau 1957 presented a timely opportunity to re-appraise the Hansaviertel in Berlin and the New Building movement. In this context, Nordic conceptions of architecture and town planning seemed particularly worthy of critical reflection. The well-known Swedish peoples home (folkhem), as well as various national strands of modernisation, architectural preferences, and even geopolitical considerations play a role in the formation of the Nordic model. The contributors to this volume have taken the example of the Hansaviertel as an opportunity to investigate the Nordic-German exchange of modernist ideas aesthetically, socio-culturally and thematically.
