The property, located in Follonica, consists of an urban lot with a small volume with a plan, which faces its own courtyard / garden, connected by an underground level.The town of Follonica grew up around the foundry wanted by Leopold II of Tuscany in 1834 that had a significant economic and cultural importance. The use of iron and its derivatives are still typical of the city since Etruscan times.In this context that the idea of the project using the iron as an element of renewal in the restructuring.The absence of light and dialogue between inside and outside has led to the opening of the south side of the volume on the ground floor and a cut in the floor of the basement volume. The structure in profiles of iron necessary for structural change becomes the skeleton of the building from the internal space is projected to the outside where a sun screen with a curtain made from the recovery of nautical sails runs on it going for so adjust the supply of light and heat in different seasons.The cut overhead becomes, on the surface, a book that outlines the space outside, chanting in different areas for their materiality. A band floating slabs of lava stone hammered is serving outside the main area, the sheets are adjusted to encompass a variety of uses, a slight flare that creates holes with a shower and spot lights. The floor of gravel takes the function as a regulator of heat to the slab of the basement and the green refers to the idea that hortus conclusus of medieval gardens.These areas are connected with the outside world via a portal that finds its form from the lines of the building, also in iron, left to rust naturally and then treated with oils to enhance its real materiality.Clean lines and the coplanarity of surfaces create a constant dialogue between interior and exterior.The office / workshop is designed for close contacts between areas served and serving areas;The services the libraries and furnishings are placed in niches in the wall, looking out on the workspace.In this way the space is free, so pure in its form.The element iron is also found in the tables and niches as the main theme of form and materiality.Each element of composition is thus perceived by its functional expression.
