Londoners should have learnt to ignore the anaemic hallucinations plastered on new-build hoardings. They usually contain the same components – a city bathed in permanent sun, populated by adults of unidentifiable ages who stroll aimlessly through the landscaped parkland surrounding their new apartments, with not a high-rise social housing building in the vicinity. Most worryingly in these CGI renders is the implied position of the viewer – frequently these images show the dappling of trees or foliage creeping into frame, suggesting the impoverished onlooker gazes at these people from behind a tree or bush. They are rich, smugly unaware of onlookers. We are perverts. Peeping Toms watching a development paradise.
