Kitchen Extension Planning Permission
Gaining planning permission for a kitchen extension can take as long as the building work itself, which is why many clients prefer to build their extensions as permitted developments. However, not all clients have this luxury as there are limitations placed on permitted developments for listed buildings, houses in conservation areas, and houses that have already been developed.
If your kitchen extension can be built as a permitted development, there will be a few restrictions placed on the building work. Permitted developments are subject to the following limitations:
- The kitchen extension must not be larger than half the area of land around the ‘original house’
- The extension should not extend in front of the principal election or side elevation fronting a highway
- The highest part of the extension should not be higher than the highest part of the roof
- The extension should not extend more than 3 meters beyond the original house for an attached house, or 4 meters for a detached house
- The extension cannot be more than 4 meters high
- Side extensions should be no more than half the width of the original house
- The extension cannot include a veranda, balcony, or raised platform
- The extension should be built in materials that look similar to the existing house
It’s important to remember that there is a limit to how many permitted developments can be added to a house – if you have already converted your loft or added a garage as a permitted development, you should check with your local authority to see whether additional developments are allowed.
Applying for Planning Permission
If you require planning permission or would like more flexibility in your design, you will need the architect to draw up detailed plans to submit with your planning application. The planning process takes 8-10 weeks, and may require you to resubmit or alter the plans before gaining approval. We partner with architectural firms throughout London to ensure that this process goes smoothly – they will submit the planning application on your behalf and continue working on it until it has been approved. Their extensive experience in the Clapham and Wandsworth areas mean that their applications are usually approved quickly, with no need to resubmit.
