There is not unanimity everywhere because land prices and build prices are dramatically different in different parts of the country. We see that even more starkly with prefabricated housing. The proportionate cost for someone who sells a house for £600,000 in London, which would be a tiny one, or £600,000 in an area like mine, which would be rather a large house, is very different. There is a danger that if the planning fees for cheap, affordable housing are too high, that will discourage self-build and small developers.
