'Grand Designs' is really just another, albeit upmarket, version of schadenfreude TV whereby we smug viewers watch how an an expensive car crash at the hands of foolish, uninformed participants is rescued at the last minute, overseen by a smug, knowing presenter. Compulsive viewing!
One of my children knows a couple who were rejected by 'Location, Location, Location' for being, effectively, too normal and engaging.
The sad thing about 'Grand Designs' is that, often, beautiful old buildings are ruined by makeovers designed to show the 'taste' of people who know nothing about history, architecture, proportions, building materials or the vernacular. Kevin McCloud should know better about such matters and is, therefore, much to be blamed.
Has anyone else noticed how modern architects rave about Corbusier but live in Lutyens? My solution for the hideous excesses of much modern building would be to pass a law saying that architects could only live in something they designed. Then we would see some beautiful buildings.
