ABSTRACT
This chapter begins with a presentation of a territorial outlook. It describes public space in terms of territorial complexity. Territorial complexity conceives the co-existence of a large number of non-hierarchical and polyrhythmic territorial productions at one place. Interstitiality presents a seed for something new, a hybrid. In this sense, a concept like serendipity actually seems to have some bearing on the debate concerning what public domains should accommodate. Serendipity and its role in science and as a strategy seem increasingly important to recognise in a world obsessed with predictability. Nilsson, material responsivity indicates the possibility of materialites to respond to bodily techniques and skills, and this ability, to afford a certain use is an important prerequisite for the production of territorial appropriations and associations. Architecture plays an important part in all forms of territorialisation, and could contribute both to an increase and a decrease of territorial complexity.
