Type construction
Standardised, prefabricated components were used to cut planning and building costs of residential housing (see also serial construction). Unlike estates in Dessau or Frankfurt, which had to conform to style and historical guidelines, most of Berlin’s World Heritage estates drew on a relatively conventional method of brick construction. Serial construction was employed only for the wooden components (such as doors, windows and staircases) and the ceilings, which often consisted of hollow concrete blocks.
