The goal is to provide a space for all the present and future needs of the inhabitants. An interactive virtual 4D platform gathers, processes, negotiates and displays the spatial and temporal conditions. Based on that a geometry is generated, outlining spaces equipped with connecting/dividing transformable walls, ceilings and floors. Due to this system, users are be able to gradually expand, shrink or even move their space across the entire building.
