To get a catastrophic failure on this level you’ve got to start with the basics, really, really bad urban design. Architects Alison and Peter Smithson did just that with a plan so appalling that they were never trusted with another large scale public project ever again. Now add some seriously poor quality building to the mix and finish off with years of under investment. Welcome to the architectural, structural and social disaster that is the Robin Hood Garden Estate in South Bromley. But things are about to change, a recent JV between Tower Hamlets and English Partnerships plans to demolish the estate to provide over 3,000 new homes. They’ve even got a new name for it, Blackwall Reach.
