The construction of the 4-storey apartment blocks was done much faster due to the type of the buildings using prefabricated panels, in one of the first large-scale uses of prefabs in apartment blocks. The 9-storey apartment blocks used the more traditional construction methods. 5500 apartments were planned to be built in the first stage: the goal was achieved in 1968, but construction works were completed by around 1976. The buildings closer to Piața Sudului were also built at the same time.
