The Local Government Association has called for an independent review of permitted development rights after the government made a number of the temporary measures permanent.

Temporary rules that allow extensions to private homes without having to go through the planning process had been due to lapse at the end of this month, but these have now been made permanent.

As well as enabling householders to carry out work on their homes without the need for planning permission, permitted development rights have meant developers can turn disused offices and other non-residential space into homes.
