One of the main trends in public space has been to minimize riks- resulting in mini-cities in which risk has all but been removed. These are places of safety and certainty. On the other hand, much of the joy of public spaces comes from their surprising qualities, from not always knowing them or the people who populate them. Here, the tendency is to encourage risk, to create places of uncertainty. This is an essential tension in public space- whether to remove risk, and so eliminate danger, or to tolerate or even encourage risk, and so enjoy the unexpectedness of our cities and fellow citizens.
