Can I install patio doors to the rear of my house where there is currently a single external door?
Installing patio doors at the rear of your house is likely to fall under permitted development rights, meaning an application for planning permission is not required, provided certain limits and conditions are met.
The doors should be of similar appearance to those previously used, if they are not then generally planning permission will be required.
If you live in a listed building, you will need listed building consent for any significant works.
If you live in a designated area such as a conservation area or national park, then additional restrictions may be in place.
If you are unsure whether the work falls within permitted development rights you can check with your local planning authority or submit a lawful development certificate to prove the change is lawful and prevent any future enforcement action.
