This research aims to uncover new insights into minority housing strategies and their impact on densely populated urban areas. The study assumes that as space becomes scarce, inter and intra groups interactions in the urban space motivate people to maximize the utility of the resources at their disposal. This stretch of the built environment provides them with critical selective advantages and a sense of security and belonging. 
Based on two neighbourhoods in London, it contributes to our understanding of housing decisions in the context of illegality and shows the capacity of a given urban form for adaptation: It creates a new semi-private/public space, partly segregated yet deeply integrated; a sphere that, on the one hand, enables traditional nested places and, on the other, a fertile environment for integration. This manuscript contributes two new ideas to the knowledge base of residential selections and the geography of opportunities. The first is a detailed analysis of a hyper-segregation/integration pattern resulting from complementary residential strategies operating at the individual unit level. The second is multidimensional stretching, a bottom-up initiation that allows individuals to maximize resources through territorial and spatial practices.
