Economic downturns are the coitus interruptus of major landscape and urban planning projects, but they bring unexpected benefits. In the 1970’s many of us lived rent free throughout central London in the empty properties the local authorities had bought up and then not had the money to redevelop. During the 1980’s we gambolled through the derelict wastelands of a half-completed Isle of Dogs in landscapes stuck in a charming time warp between the abandoned Port of London and Canary Wharf. We took our girlfriends up to the forgotten terraces of the old Crystal Palace, where sphinxes emerged from clouds of flowering willowherb. All gone, these buildings and places, they are all designed spaces now, some of them very good indeed, all of them contributing once more to the wealth of the nation. But, what is it about abandoned or fallow projects, half completed places? Where does the romance go when we architects, engineers and landscape architects finally get the go ahead from our clients to finish them off? Perhaps it is just me, but these are the places that I remember the best and miss the most. The images show Lulu Island, created at enormous expense off the coast of Abu Dhabi. One day it will be bristling with residential tower blocks and all manner of designed parkland. For now it’s on hold. On the eastern side, the best views of Abu Dhabi City, on the western side a 5 km beach whose shade structures are one by one collapsing into the sand. Why do we have to wreck these places with finished projects?
