The form of this 80ms house derives from the tracks drawn on the ground. It is a simple shape, characterized by a pure geometry (the parallelepiped) and, like the rest of our projects, it is not governed by the quest for an architectural shape conceived exclusively like something changeable, what is the really matters is the expression of a concept represented in its essence. So the grid, characterized by 3x3 meter panes, becomes the location of the movement; a space in which the motion expression entrusted to the architectural elements generates a dimension of the "Undefined", a space "out of itself" in which total absence reigns. In one of his tales Blanchot describes a world in which the homes appear places without place, closed spaces, defended even though they’re left to the power of the winds. Along the grid made of steel tracks run the walls, also made of recycled steel (6 cm width isolated panels low environmental impact) that, in a relatively short period of time, can change the space and thus altering the perception, moving from total closure to absolute and complete opening. A computer placed at the centre of the housing complex determines these variations of movement, space and time. Inside-outside, close-open become extreme spatial conditions among which covered and opened spaces, open and uncovered spaces (by extending the partitions towards the outside of the structure's covering it is possible to create enclosed or open spaces, in which you stay in the open) or closed and open spaces can be laid out. As the external enclosure remains closed it is possible to modify the inner space, making it flexible and adaptable to various needs. The only fixed elements are the concrete platform, a floor-base on which the tracks on which the walls slide and the utilities are set.
