Of the reconstructed buildings, only the Goethe House was largely restored to the original. Most other reconstructions were more or less simplified (for example the houses Silberberg, Frauenstein and Salzhaus in the Roman complex) or with modern additions (for example the stone house). Much of the former old town was built on in the simple style of the 1950s. The main result was multi-storey houses, partly as block perimeter development, partly as loosened row buildings, often with green inner courtyards. In addition, large-scale functional buildings such as the Federal Audit Office building in Frankfurt am Main, the Kleinmarkthalle and numerous parking garages were erected, including in 1956 the parking garage Hauptwache as Germany's first public parking garage.
