Karl-Marx-Hof was officially inaugurated in Vienna, epitomizing interwar municipal social housing by pairing a monumental modern complex with extensive services (baths, laundries, childcare, and more).
Rotterdam’s Bergpolderflat opened, an early, influential example of a modernist gallery-access apartment building in Dutch social housing, using a steel skeleton and emphasizing light, air, and functional planning.
Construction began on Clichy’s Maison du Peuple, a landmark of French modernism combining a market and public facilities with innovative engineering and envelope solutions—showing how modern construction could serve civic and worker-oriented programs.
Construction began on Le Corbusier’s Unité d’Habitation in Marseille, an influential postwar social-housing prototype that organized apartments and shared services into a “vertical city,” shaping later European mass-housing approaches.
Le Corbusier’s Marseille Unité d’Habitation was inaugurated, demonstrating a high-density, amenity-rich model for public and social housing (shops, shared spaces, and communal facilities) within a modernist megastructure.
Sheffield City Council began constructing Park Hill, a large deck-access (“streets in the sky”) estate influenced by modernist housing thinking and intended as a comprehensive rehousing solution replacing cleared inner-city slums.
