Flexibility is freedom, insecurity, the unexpected. However, as a consequence of the security obsession in all layers of society, anything unexpected is avoided, which leads to a sterile, transparent and neutral environment, resulting in a rigid city. But rigidity in turn leads to fear. People do not want to be checked, pressed in fixed structures, they want to choose and design. What is their freedom? Can they use the city space as they want? The perfect space I think is a flexible space that provides privacy and freedom, but which is not enclosed.
