Frequently Asked Questions

Can I extend in a National Park?

What is the maximum rear projection allowed?

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.

Can I extend my house in a flood zone?

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