The city is the context for the lives of most of us. The city offers opportunities by fencing us in, the city offers shelter and safety. A fascination for the city, in fact for all clusters of human activity – and buildings – how people live together, attracted me to urbanism. A new capital city for Korea differs from an inner city neighborhood in Dutch Enschede. In both the small and the big scale are important. What can be connected and what can better be separated is the first question. Urbanism imagines the possibilities people can use. Realized urbanism takes away all the other opportunities, urbanism is an important activity.
