#Vienna gets deserved attention for its #AffordableHousing policies over the last century. One of the least know is tightly regulating the tearing down of buildings, making it one of the oldest housing stocks in Europe. When a building is torn down to build a new one, then there is still just one building. If old ones are kept, then a new building means increased housing supply. Developers like tearing down since they can make massive profits in proven neighborhoods. https://wien.orf.at/stories/3203136/
