Trade Union School of ADGB
Designed by Hannes Meyer and Hans Wittwer, the school of the ADGB (Federation of German Trade Unions) in Bernau near Berlin is still considered to be a paradigmatic example of functional architecture. The architectural style of the school, built in 1930 for union functionaries, corresponds with that of an industrial facility in that it dispenses entirely with extraneous details.
