Currently there is hardly any other theme that fascinates us to such an extent as urban space. In recent years we have devoted a number of issues to the space in-between that is so difficult to grasp. And there is an obvious reason for our persistence: in this area a great deal still remains to be done. The building boom of the last twenty years has brought with it a considerable amount of good architecture, but little urban design of quality. At regards the design of urban space Swiss architects show remarkable weaknesses. This is, in part, due to a training in which urban design is often misunderstood as “grouping buildings”. On the other hand hardly any impulses come from the clients: the space between buildings cannot be rented out. And why be satisfied with anything less than the maximum return?
