Extension and loft conversion FAQs

Do I need planning permission for an extension or loft conversion?

Many single-storey rear extensions and loft conversions fall under permitted development, so they don't need full planning permission. There are size and design limits, and Building Regulations approval is still required. Your local council can confirm what applies to your property, and we're happy to talk it through when we quote.

How much does a house extension cost?

Every project is different, so we price each one individually. Our quotes are itemised, so you can see exactly where your money goes before you commit.

Do you guarantee your work?

Yes. Every job comes with our 12-month workmanship warranty.
