Well, the CBD of Johannesburg is pretty abandoned... Urban decay/blight and ''white flight'' in the CBD caused many corporate offices to move from downtown Joburg to Sandton (part of Johannesburg metropolitan area) in the late 1990s. Sandton has become the new financial district of South Africa and Johannesburg's premier business centre. Of course, there are lots of projects ongoing in Sandton.I have a question regarding Johannesburg. Why no more skyscrapers over 100m will be built in the city anyway? Is there a reason?
