Traditional andalusian architecture. Active preservation of the patio house: type, technique and project.

The research falls within the context of the recovery 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 goal is to re-read this transformative process and identify the codes that have regulated it in order to ensure its continuity through active conservation interventions on the building tissue that ensure its protection on the one hand and regenerative recovery on the other. The relationship between type, technique and project is assumed as the operational key of a methodology that seeks the definition not only of the qualitative parameters attributable to the recognition of the peculiarities and the complex of values of the historical building heritage and to their translation in a critical-interpretative key in the levels of transformability, but also of those of a quantitative type, referable to the performance levels connected to a necessary adaptation to new needs. The paper intends to report the results of the experimentation of the research work, conducted in the framework of collaborative relationships with the University of Seville, on an old traditional Andalusian patio house located in the historic center of Seville, in Calle San Vicente 24. The building has its first testimony in the Sevillian Municipal Archives in 1929; it is then the subject of various 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 nineties this was transformed into a sort of convent and later definitively abandoned. The experimentation of the project, starting from the framework of the needs posed by the new owner, the Cultural Foundation "Centros de Estudios Andaluces", seeks a model of use compatible with the characteristics of the type, investigated in the complex of its functional, formal and constructive aspects and defines congruent intervention strategies. The design intentions are finally translated into technicalconstruction choices that find precise and punctual detailed solutions within the building schedule according to technical codes referable to a form of advanced craftsmanship, both in the use of traditional and innovative materials
