FAQs

On average, a single-storey extension starts from £1,500-£2,500 per m², while a two-storey extension costs slightly more due to extra structural work. The cost depends on factors like size, materials, and location.

Not necessarily. Many single-storey extensions fall under permitted development rights, but larger or listed properties may require planning permission. Our team will handle all planning approvals for you.

Typically takes 10-16 weeks for a standard kitchen or single-storey extension, depending on complexity. We provide a detailed timeline at the start of your project.

In the UK, you can build certain types of house extensions without needing planning permission under Permitted Development (PD) Rights, as long as they meet specific criteria.

You don’t legally need an architect for an extension, but hiring one can help with design, planning permission, and maximising space. For complex projects, an architect ensures a smoother process and better results.
