The contemporary forms of the big city cores are post-art forms in fact, belonging to the post-esthetic art stream - in which „form is minimal and contents is maximal”, becoming some kind of „cancer aesthetics” manifest. City core's public space becomes the place of conflict between the „old” urban plan, based on aesthetic art against rather ugly market oriented and oversized buildings and spatial forms. Inside the so developing city cores among business towers and shopping malls, there is a lack of space for beautiful architecture, beautiful churches, synagogues, temples and parks, which would let the humans to be humans, not only as a supplement to the computers of some anonymous corporations. Contemporary Warsaw city core shows an example of urban marketing idea and faith in corporate money power, expressed throughout post-aesthetic forms of buildings combined with the triumph of consumption, and contrasting with pre-war remains of art nuveau buildings. It shows „success” of real estate market, forcing the price growth up against building density factor. At the same time, though, this is a spatial planning failure as an urban composition and a „third dimension” tool.
