Temporary rules, which allowed bigger single-story rear extensions without a full planning application, are being made permanent. Additions to terraced and semi-detached homes can be up to 6 metres, while detached houses will be able to add even larger structures, up to 8 metres long. Neighbours will still need to be consulted and can raise objections to extensions.

Since 2013, 110,000 people have taken advantage of the temporary rules, which doubled the previous limits of extensions that didn't require planning permission from the local authority.

Instead of waiting possibly months for approval, homeowners notify the council of the building work beforehand, and council officials inform the neighbours.

If they raise concerns, the council decides if the extension is likely to harm the character or enjoyment of the area, and may block the plans.

In Scotland, Wales, and Northern Ireland, rear extensions more than 3 or 4 metres long will continue to require a full planning application, which places the design and impact of the building under more scrutiny.

Housing minister Kit Malthouse said the change in England means "families can grow without being forced to move".

He said: "These measures will help families extend their properties without battling through time-consuming red tape."
