This manual deals with the vast category of specialised buildings that, stemming from basic structures, have gradually reached a whole new level of “intentionality” and “critical consciousness”. As happened with basic buildings, the operational architectural knowledge method we hereby suggest leads to the creation of a multi-layered analysis framework. Indeed, the observation and interpretation of building elements determines the shape, structure and purpose of public buildings. The aim was to create a manual enabling the understanding of specialised buildings following a “processual-typology” methodology. Better understanding of the evolution of a cultural area’s anthropic elements is an architect’s basic tool for an ethical, landscape-friendly approach to design.@en
