Design proposal. The municipal administration has asked to evaluate design strategies for the relocation of their public offices in town. Right across the street from the existing public offices, a small and modest freestanding building used as a library, occupies a wedge-like open space between the tight urban surrounding, typical of a medieval center. The limited open site, even after the demolition of the sole building at its center, has been the actual strength for a new municipal building for the town of Casnigo. The formal quality of the new building is of an interstitial type, which definitely derivates from the historical surrounding. The carving process of the design, as subtraction from a prismatic volume, creates a conglomerate of masses of a human scale and offers protected open areas and explorative views from the interior of the building. One access to the interior of the building is created by a ramp which offers a continuous approach in the mostly pedestrian circulation of the surrounding area.
