Robert Schumannstraat Housing in Utrecht

 'This modest block of four dwellings was built in 1931-32 designed by Gerrit Rietveld, who was working at that time on a prototype for mass housing.  Steel frame, wooden floors, brick party walls, sliding partitions, white stucco walls and flat roofs are all proof that Rietveld had embraced functionalism.'
