The relevance of componĕre architecture as a condenser and interpreter of the urban landscape, brings central the discourse on the construction and practice of urban regeneration. By the term construction we mean the “unitary phenomenon” of inseparable elements - figurative, formal, structural, technical, cultural, social - that put the project at the heart of architectural research. With the urban regeneration project, we intend to protect the architecture that supports the aesthetics of the contexts with respect to the aesthetics of the self referential object, that is, the architecture of the relationships that build the city, as well as the work of art in general. The object is opposed to the architecture as outil, that is, as “architecture in function” of the construction of simultaneous space-places. Elements, parts, fragments mingling, so that the built landscapes can continue to express their time in mutation. This perspective requires combining the project into mestizo frames, made intelligible by the relationships.
