Frequently Asked Questions

What is retrospective planning permission?

Retrospective applications seek approval for work already carried out.

Can I extend my house in a flood zone?

Extensions in flood risk areas may require additional assessments and possibly planning permission.

How high can my extension be?

Height limits vary, but rear extensions under permitted development generally cannot exceed four metres for detached houses or three metres for others.

Does building regulations approval still apply?

Yes. Even if planning permission is not required, building regulations approval is usually still necessary.

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.

Does an Article 4 Direction affect my extension plans?

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