SHOOT: There are a few points to consider, chief among them, is living in a multi-story building society-enhancing? Does it lead to happy communities or do the more compact living arrangements promote criminal activity? Then there is also the question of energy. High rise building are less energy efficient than european style multi-use buildings, often 4 story's high. Houses/suburbia aren't the answer either, as these promote a car dependent and energy dependent system. The answer is designing a walkable community around a town plan, having a multidisplinary [multi-use] approach to buildings.
THE City of Cape Town is planning to build 14-storey blocks of flats in a bid to beat its massive housing backlog.
