On reborn ovals and flipped squares

Wilhelm Leuschner Square lies on the southern inner-city ring road, one of the very few, still empty, prime premises in Leipzig's city centre. Little pressure to develop combined with hopes for quality development has kept the site on hold for over two decades. A precise analysis of the square's history throws light on the main aspects of such automatic urban development, and results in a strategy that combines three approaches:
Ad hoc urbanism – urban development based on majority rule "Robust scaffolding" urbanism – development in line with a previously formulated concept that has already defined public spaces and building lots Free-style urbanism – based on trial and error: ditch what fails and continue with what works.
