Design Technics for the Intervention on Architectural Heritage. The Case of the Partial Recomposition of Vaulted Spaces

This article aims to research the design techniques used in heritage works publicly recognised through awards and publications. Specifically, it studies the case of interventions that seek to recompose vaulted spaces that have partially disappeared. In order to carry out the research, four works have been selected and analysed and studied both individually and comparatively to understand the benefits of each one of them: San Filippo Neri Oratory in Bologna, Chapel of the Counts of Fuensaldaña in Valladolid, Church of the Pious Schools of the College of San Fernando in Madrid and St. Peter's Basilica in Syracuse. The result obtained is the recognition of a set of techniques of great design interest that, when properly applied, can be extrapolated to future interventions.
