This multipurpose object is inspired by the idea of playing with the x and y-axes – the horizontal and the vertical – to create diverse volumes and perform equally varied functions. The base is a set of hinged planes applied to a Cartesian grid; they can be opened or closed to create three-dimensional depth or flattened to the point of almost disappearing on the wall. The result is an intelligent boiserie that, thanks to a multiple system of folding planes, can become a container, bookshelf or dividing element. What is more, the hinged elements project from the wall, transforming into folding screens that further articulate architectural space. More than physical possibilities offered by this piece of furniture, opening and closing become tools for designing spatial functions in relation to changing needs.
