It was recently announced that the Government has overhauled the rules which used to require people to put in a full planning application for single storey rear work.

But what other extensions or adjustments can homeowners build or make that don’t require planning permission?

There are certain things you can build or adjust which don’t require planning permission, including:

- Adding single storey extensions of up to four metres by six metres

- Moving windows and doors, as long as you're not looking directly into neighbouring properties

- Moving interior walls, as long as the total footprint of the house stays the same

- Loft conversions of up to 50 cubic metres for detached and semi-detached properties - or 40 cubic metres for terrace houses

If youre planning to do work on your home, this falls under the permitted development rights for householders.

- Single storey conservatories of up to four metres by six metres

- Outbuildings that double up as office space

- A porch of up to three metres tall

- Garden decking as long as it's no more than 30cm above ground

- Swimming pool as long as it's no bigger than 50 per cent of the size of the garden

Permitted development rights for householders

If you’re planning to do work on your home, this falls under the ‘permitted development rights for householders’.

According to Gov.uk, “permitted development rights allow householders to improve and extend their homes without the need to apply for planning permission where that would be out of proportion with the impact of works carried out.”

Converting your loft

If you’re planning to do work on your loft, this falls under the ‘permitted development rights for householders’.

This means that you can make certain changes to your home without permission, but this is subject to a few limitations.

You are allowed to extend the space by adding dormer windows or slightly change the shape of the roof - but this is as long as it isn't higher or wider than the existing dimensions.

For semi-detached and detached houses, a loft conversion must not add any more than 50m³ of space to the house - or 40m³ for terrace houses.

However, some parts of the build will probably need building regulation approval, which set out minimum standards for construction and health and safety - so it’s always best to check.

A professional builder will be able to let you know if the work meets regulations, such as fire safety and sound insulation.

There are a few other rules too, including:

- If your loft conversion involves extending your roof higher than the existing peak then you'll still need to get planning permission

- To stay within the permitted development rules, the materials used must be similar in appearance to the rest of your home

- Any side-facing windows need to be frosted or patterned and the fastenings must be 1.7m or more above the floor

Note: You will still need to apply for planning permission before carrying out any work if you live on the top floor of a flat or your home is in a conservation area

If you don't get the right permissions, you may be asked to take down any parts of the build which are concerning.

If you’re unsure if the work you’re planning to do meets the legal requirements, contact you local authority or visit gov.uk
