From 1924 onwards, new housing estates were being built in Frankfurt with a total of more than 10,000 apartments. Even the kitchens for all the flats were planned – and were fitted. Viennese architect Margarete Schütte-Lihotzky designed the Frankfurt Kitchen. It is considered the prototype of a modern fitted kitchen. Everything has been streamlined to fit a very small footprint and arranged such that the housework and cooking can be done in a minimal space and with very little effort.
