Frequently Asked Questions:

Do I need planning permission for an extension?
Some extensions fall under Permitted Development rights, while others require full planning permission. We’ll advise you based on your location, size, and layout.

Can you submit the application for me?
Yes. We regularly act as agents for our clients and can handle the entire planning process on your behalf.

Do you cover building control drawings too?
Yes, this is available as an optional add-on. We can prepare technical packs suitable for Building Control approval and contractor use.

How much does it cost?
Prices vary depending on the size and complexity of the extension. Please contact us for a fast, fixed quote with no obligation.
