The purpose of this work is to study the effects of multiculturalism in private life and to analyze the emergent dwelling patterns that are product of these processes in Mexico City Metropolitan Area. Crossbred Parcelation is a term created to define the postsuburban condition as an alternative method of description and analysis where the proletarian house emerges as a testing field of architectural ideas considering its physical, social and imaginary configuration. The concept of house fostering identity, class, privacy. Intimacy and domesticity is defied by an alternative understanding of social mobility leading to temporary occupancy patterns, thus reflecting in a more flexible and open spatial arrangement. The analysis focuses on contemporary dwelling patterns in Mexico City, especially those in the multicultural matrix of the expanding periphery. The lived experience of the ''Final House'' lead us to reconsider our scope to approach to the architectural and urban practices, to construct a platform characterized by experimentation and alternative mechanisms, for those who aim to make a contribution to social housing design.
