Build, Build, Build Costing the Earth

With an ever greater demand for more housing, and Boris Johnson calling for the country to "build buld bulid" post lockdown, Peter Gibbs looks at current trends in house-building. Are the government's plans for "garden communities" as environmentally-friendly as they sound? And how could developers be encouraged to build in a way which incorporates nature rather than squeezing it out?
