Do You Need Planning Permissions For An Extension?

If you are looking to purchase a house extension for your home in Milton Keynes, you may be wondering if you need planning permission. As this can depend on many factors, it can be challenging to understand if a planning permission is required for your brand-new extension. In this blog, we take a look at whether you need planning permission for your new conservatory or extension.

If your new conservatory is built within permitted development rights, you will not need planning permission. 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 the works carried out. In most cases, a planning permission is not required for a new extension or conservatory. However, you must check before any work is started. It can depend on many factors, including the size, location, and type of home to which you are adding an extension.

You can usually build an extension without planning permission if it follows the below:

Single-storey extensions:

  • No more than 4 meters high.
  • No more than 3 metres deep (for attached houses) or 4 metres deep (for detached houses).
  • No more than half the land around the original house is covered.

Double-storey extensions:

  • No taller than the original house.
  • Must be at least 7 metres from the rear boundary.
  • No balconies, verandas, or raised platforms.

Side extensions:

  • No more than 4 meters high.
  • The maximum width is half the width of the original house.

You will need planning permission if it fails to meet the above or:

  • If your home is a listed building.
  • The extension or conservatory impacts your neighbours.
  • You live in a flat or a maisonette.
  • If the home is in a conservation area or national park.
