The traditional Andalusian heritage of the patio house. Methodological guidelines and design experimentation for active conservation

The research falls within the context of the refurbishment and regeneration of the predominantly residential building tissue in consolidated urban contexts which, subject to a continuous process of modification, are characterized in terms of a palimpsest. The paper intends to report the results of the design experimentation carried out in the context of the graduate thesis laboratory within the framework of the collaboration relationships with the University of Seville, on an old traditional Andalusian patio house located in the historic center of Seville subject to several interventions up to that of 1952 by the Regionalist architect Antonio Delgado y Roig through which the patio house finds its own precise conformation. In the methodology, the type/technique/project polynomial is taken as an interpretative key capable of restoring the characterization of the Andalusian patio house both in the "knowledge for the project" and in the "project for refurbishment" phases. The active conservation project is characterized as an iterative process capable of delineating a condition of habitability available to absorb regenerative processes, starting from the assumption of operating on a "mature" system, assumed as an invariant subsystem, to be integrated with components with selective transformability, variant elements capable of ensuring the adaptive refurbishment of the building.
