Do I need planning permission?

Some types of development, in non-protected areas, may not need any planning permission.

However, it is important to check with the Planning Team before starting any work. 

For small-scale proposals, you are advised to submit a Lawful Development Certificate application for consideration or consult the Planning Portal

Single developments that don't require permission

House extensions

You can build a single-storey extension at the back of your house without full planning permission, but there are size limits:

  • Detached houses: You can extend between 4 metres and 8 metres out from the back of the house.
  • Other houses (like terraced or semi-detached): You can extend between 3 metres and 6 metres out.

However, you must also go through a consultation process (your neighbours will be informed and can raise concerns).

Also, your extension still has to meet all the usual rules and conditions that apply under "permitted development" (things like height limits, materials, and how much of your garden you’re building on).

For full details, you should check the official guidance on permitted development rights:

Business premises

In some cases, business premises can change to other business, community, and leisure uses for a period of up to 2 years.

Some office premises can be converted to houses, subject to prior approval covering flooding, highways and transport issues, noise and contamination.

For a period of 3 years, the size limits and percentage increases for some businesses are also to be doubled.

Dropped Kerbs

A dropped kerb allows vehicles to cross the pavement from the road onto a driveway, and in some instances may need planning permission.

Guidance

The planning portal provides some simple guidance about whether you need planning permission for common home projects like loft conversions, porches, and small single-storey extensions:
