ABSTRACT
The aim of this chapter is twofold: to start and develop a conceptual discussion on interstitial space as an important issue of territorial change in the use of everyday urban spaces, and to describe the relationship between interstitial practices and the territorial transformation of retail spaces. It examines how interstitial urban practices affect and is affected by the evolution of new territories of consumption such as pedestrian precincts, retail parks, airport malls, museum stores, railway-transport-oriented retail, concept stores. The chapter gives a theoretical introduction to interstitial space, using two cases, the disturbed but spatially inventive children at Bruno Bettelheim's school in the 1940s and the spatial transformations of the nineteenth century book collector Thomas Phillipps. In the chapter, the author uses the concept of singularization as a way of dealing with the formation and evolution of new retail building types.
