The project involves the interior spaces of a villa situated in the lush hilly context that, developing behind the city of Prato, opens up to the view of the Florentine plain and the mountains of Calvana. The studio has created a domestic environment that plays with the differences in height present in the valuable original building of the 1980s to create an interior characterized by lively and detailed spatial connections but also, at the same time, able to define autonomous zones each enjoying its own privacy. The sophisticated spatial connection that characterizes the project is not only accomplished through interventions on the structure of the walls. It is in fact the design of an integrated furnishing system that connects different areas of the house, giving each one its own identity. The living area consists of four large connected areas: the living room, the reading and music corner, the dining room and the kitchen. The piece of furniture therefore performs various tasks: it is a bench, a container, a music record display, a bookcase, a divider between different areas. The cabinet is made of open-pore ash wood lacquered in blue, to highlight not only the color but also the veins of the material. It has inserts and open elements in matt lacquered wood with a touch of electric blue. The bookcase, which is the focal point of the room, is made of teak wall panels. Horizontal milling helps to integrate the shelves made of painted sheet steel which give a sense of lightness and solidity. The cabinet under the bookcase, with concealed drawers, acts as a bench and container. An element, designed to store music records and to put a selection on display, acts as a divider with the dining area. The staircase is the real fulcrum of the house, the point where the different levels are connected, highlighting the various passages of altitude. The staircase becomes a sort of micro-architecture inside the house, a playful space to live in. Circulation element, but also rest area, reception area, container cabinet, filter and separation device, frame for climbing. Like other furnishings, the staircase also offers elements of surprise; gradually, as it unfolds, the structure becomes lighter and changes its appearance. The first ramp consists of a monolithic wooden element faced in teak, an element that anchors the staircase to the ground and invites one to walk down it safely. While in the second ramp the staircase seems to dematerialize thanks to the slender powder-coated iron structure, up to the last portion where the staircase is made of painted perforated sheet metal. The staircase, from being extremely solid, becomes permeable to light and movement and, as it ascends, it almost seems to float in a void.
