Buildings are not empty containers awaiting their inhabitants. They are themselves composed of a large and ever-changing array of objects. To maximize opportunities for appropriation, expand the class of objects traditionally dealt with by architects to encompass all possible objects (existing, belongings, proposed, and suggested) such as a wall, a sink, a chair, that might occupy a particular area at a particular moment in a project. Prioritizing care for only certain objects –such as walls, floors, ceilings, etc. — would limit the forces of appropriation.
