Frequently Asked Questions

Will neighbours be notified?

Under prior approval procedures or planning applications, neighbours are typically notified.

How much does a planning application cost?

Fees vary depending on project type and local authority charges.

Can I extend a house that has already been extended?

Permitted development limits are cumulative, so previous extensions may reduce what is still allowed.

What is the 45-degree rule?

The 45-degree rule is a guideline used by some councils to assess impact on neighbouring properties, particularly in relation to light and outlook.

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.

What is retrospective planning permission?

Retrospective applications seek approval for work already carried out.
