I see Boris Johnson, the London mayor, plans to reinstate Parker Morris space standards in London’s new housing (27 June, page 12).

Here is another example of a politician – with the best of intentions – about to make worse the situation he seeks to improve. As someone who applied Parker Morris space standards in the sixties, I saw their effects – one of which was increased building costs and in some cases fewer homes being built.

When interviewing residents in homes built to Parker Morris standards I found most of them wanted even more space – usually storage space. Where do we stop?

With roughly half of the world’s energy and resources being used to construct and operate the built environment, we should be looking urgently for ways to build smaller, more efficient and better designed homes which don’t feel small, NOT larger ones.
