Frequently Asked Questions

Can I extend in a National Park?

National Parks have stricter controls and reduced permitted development rights.

How is the original house defined for measurement purposes?

The “original house” refers to the property as it stood on 1 July 1948 or when it was first built, not including later extensions.

Is there a limit on total site coverage?

Yes. Extensions and outbuildings combined must not cover more than 50% of the curtilage of the original house.

What is retrospective planning permission?

Retrospective applications seek approval for work already carried out.

Can I build right up to my boundary?

It depends on height and location. Boundary proximity affects allowable eaves height.

Will permitted development rules change?

Planning legislation can change over time, so it is important to check current regulations.
