The Waterloo of urban renewal came in Amsterdam's Jordaan neighborhood. Even in 1975, the Amsterdam city council still proposed in earnest to demolish the Jordaan. Angry Jordanians managed to foil that plan. A structure of seven houses, which originally housed at least 35 people, now houses four people. The neighborhood has totally changed, with many amenities and all within walking distance. There is no need at all to demolish when use changes. Urban construction has an enormous ability to adapt to changing uses. No canal house is still occupied as it was in the seventeenth century. Stores with two small upper dwellings under a roof in the Jordaan are now being converted into very attractive single-family homes. No one would have thought that possible at the time. But one could have known. After all, in her famous book on American cities, Jane Jacobs had already described in the early 1960s how Boston became a hip city thanks to the rehabilitation of old houses.
