Frequently Asked Questions

Can I build a wraparound extension without planning permission?

Wraparound extensions often exceed permitted development limits and usually require planning approval.

Can I extend above a single-storey extension?

Possibly, but this often requires planning permission and must comply with height and design considerations.

What is the difference between planning permission and building regulations?

Planning permission controls development impact, while building regulations ensure structural safety and compliance.

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.

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.

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.
