We create, rearrange and destroy spaces we inhabit, throughout our whole life. Houses, workplaces or streets and public squares are the material environment we influence on. However, they also shape our behaviour: tell us where and how to go, teach us values and hierarchies dominant in a society or a class we belong to. In that terms, it is no surprise that the notions of ‘building’ and ‘construction’ are never limited to physical matter. We build houses and relationships, monuments but also identities, spatial order and political order. We built past memories and will build the future ones.
