Do I need Planning Permission?
Will I Need Planning Permission for my Extension?
Planning permission may or may not be required for your proposed extension.
Under the Permitted Development Rights a large number of home extensions can be built without the requirement of planning permission.
Here is what you can do on permitted development:
- You can extend a detached dwelling by 8m to the rear only if it is a single storey or 3m if it’s double.
- But there are height restrictions-A single storey extension can not be no higher than 4m in height and ridge heights of any extension not being higher than the existing property.
- Two storey extensions must not be closer than 7m to the rear boundary. It must be built in the same or similar material to the existing dwelling.
- Side extensions must be single storey, maximum height of 4m and a width no more than half of the original building.
- In Designated Areas side extensions require planning permission and all rear extensions must be single storey.
- An extension must not result in more than half the garden being covered.
- Build a porch.
- Carry out internal alterations.
- Convert and occupy the loft space.
- Put in roof-lights or dormer windows.
- Put in new doors or windows.
All subject to design constraints for example. porch has to be less than 3m³, roof lights and dormers must not face the highway, etc.
You can only do it once and the original building is either as it was on 1st July 1948 or when it was built.
You should also keep in mind that if your house is in a Conservation Area or a National Park, the amount of work one can do under Permitted Development is usually reduced.

Building Regulations
Regardless of whether your new extension does or does not require planning permission, it will need Building Regulations Approval.
Building regulations are rules approved by Parliament laid down to ensure the minimum design and construction standards are achieved.
These cover all manner of subjects such as fire and other forms of safety, insulation, the drainage system, Etc.
Building control officers do not supervise work on your behalf. Their role is to ensure the minimum standards of the building regulations have been achieved.
To meet Building Regulations you either:
Send a Full Plan Submission -
To your local authority. In this case you pay a fee and the building inspector visits the site at the various stages of the build and inspects the work as it proceeds.
Submit a Building Notice-
This is a statement in which you inform the council that you will be complying with the regulations in building your extension and gives the building control department 48 hours notice of your intention to start the work. Surveyors will come and inspect the work at various stages and will advise you of any problems.
