SHOOT: Maybe South Africa is slightly different to London. For example, crime is a problem in South Africa. And crime is associated with low income housing/property. You may be prepared to pay millions for a swanky pad until you find its residents are raped, murdered and the contents pillaged. After that, the perceived value drops precipitously. In this context Melrose Arch remains streets ahead of the conventional (read: Old Hat) single purpose urbanism of The Houghton. Melrose Arch has a multidisciplinary approach that is sadly lacking throughout Johannesburg, South Africa and the rest of the world. It's alos known as New Urbanism. Go to Wikipedia to find out more.
My prediction is that unless the developers radically change their concept to a more affordable solution, the hulking monster on Osborne Road will be around in its present shape for quite some time.
But Nagle sees no reason to change his concept.
