Lefebvre's three spaces

"For Lefebvre it was important to distinguish between “spatial practice” properly speaking (the process of the production and reproduction of space, as well as the relationship of society to space); “representations of space,” or conceptualized space (the “space of planners, urbanists, technocratic subdividers and social engineers”); and “representational spaces” or spaces that are “directly lived,” overlaid on actual physical spaces, and appropriated symbolically."
