Frequently Asked Questions

Can I extend onto agricultural land?

Residential permitted development rights apply only within the residential curtilage.

Do conservation areas affect permitted development rights?

Yes. Properties within conservation areas often have additional restrictions, and some permitted development rights may be limited or removed entirely.

Can I convert my loft and add a dormer?

Dormer loft conversions are often permitted development within volume limits.

What happens if permitted development rights have been removed?

If rights have been removed by planning condition or Article 4 Direction, you will likely need to submit a full planning application before building.

Are side extensions allowed under permitted development?

Side extensions are permitted in some cases, but must not exceed half the width of the original house and must meet height limits.

Are there restrictions on side-facing windows?

Yes. Upper-floor side-facing windows typically must be obscure-glazed and non-opening below a certain height.
