 One of the key "forums" for this "reconstruction of the European city" was the International Building Exhibition Berlin (IBA), built in the then West Berlin from 1979 to 1985, and where the above architects had a profound influence.No Finnish architects were present in IBA, yet in Finnish cities this renewed urban attitude became evident in planning practices to the extent that urban planning under the control of the city planning authorities could set very precise demands on urban development; for example, the layouts of traditional street grids, and even the overall appearance of buildings in terms of height, streetscape, roof line, and building materials.Key examples are the planning of the areas of Itä-Pasila (western edge) and Länsi-Pasila and Katajanokka in Helsinki.
