Architecture is the result of a complex process, not linear and based on the continuous review of multiple options available with a critical attitude. It is a practice manner based on the primary role of the Idea. The act of Doing researches a balance between the three steps of working on architecture: theory, order and the final outcome. Theory is a synthesis of the background made of models, references, words and other contributions coming from other disciplines. Order transforms this background into design with a deep connection with the city, its history and its layers. The real challenge is to preserve the essence of that idea during the entire process until its final outcome. The result is a two-storey box that hosts the new AMAA branch office inside a former vaulted factory. Everything appears for what it is: the thin steel frame structure, the concrete and metal slab, the path of the electrical system with its pipes, plugs and switches, the metal frame of the windows.
