Frequently Asked Questions

Can I extend a flat under permitted development?

Flats and maisonettes generally do not benefit from permitted development rights for extensions.

Does an Article 4 Direction affect my extension plans?

Yes. Article 4 Directions remove certain permitted development rights, meaning planning permission may be required.

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.

Do permitted development rights expire?

Permitted development rights generally remain unless removed by condition or Article 4 Direction.

Can I build right up to my boundary?

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

What is the maximum size allowed under permitted development?

Size limits depend on property type and location. Detached houses may have larger rear extensions than terraced homes, subject to height and boundary constraints.
