Frequently Asked Questions

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 garden rooms permitted development?

Garden rooms may qualify if they meet size and usage limits and are not used as separate accommodation.

How much does a planning application cost?

Fees vary depending on project type and local authority charges.

What is prior approval neighbour consultation?

For larger extensions, councils notify neighbours and assess specific impacts before granting prior approval.

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.
