In the Organisations d'espaces (Organised spaces), the artist utilizes larger and more specialized mediums for each new work (parts of industrial cranes, scaffolding, tree plantings, video projection, droppings of blocks of ice by helicopter, the setting off of avalanches,etc.) to either reveal or correct the meaning of each selected space. The spaces themselves vary from a museum gallery to a construction site or to a valley. In each case, (except for post-2000 Organised spaces) a project, realized or not, is presented with the aid of a plan.
