The present project was commissioned by the City of Zurich's Building Authority in the autumn of 1960 and awarded to five architectural firms. The site to be developed, approximately 41,500 m², was partly owned by the city and partly by private landowners. For the private development – now under construction in the eastern part – only the mass distribution plan was declared binding. The further development of the city-owned buildings was entrusted to the architectural firm Pauli + Volland. Scheduling and coordination of the wall elements was handled by Systembau AG, Zurich.
