Josep Lluís Mateo characterizes his career as focused on the design and construction of new models of housing. Mateo describes a series of residential projects as being concerned with protection, the relationship between inside and outside, tensions between private and public space, and the effect of housing on urban structures. He describes a housing project in Amsterdam composed of high density single family units, stressing the roof as a domestic landscape. He presents three unbuilt competition entries, three housing projects, and a convention center in Barcelona. He explains that all of these projects deal with nature, their sites, and contextual relationships.
