Single-storey extensions in Staffordshire

Planning your single-storey extension in Staffordshire

Planning applications and lawful development certificates for Staffordshire go to the district or borough council for your town. Many single-storey extensions fall under permitted development, but not every house keeps those rights — conditions on newer estates, conservation areas and Article 4 directions can remove them. The structural work also needs Building Regulations approval, through the council's building control team or a registered building control approver.

Most of the build happens outside, so the kitchen is usually only out of action for one to three weeks near the end.
Every extension needs Building Regulations approval, even when planning permission isn't required.
Detached houses get a little more room: 4 metres as standard, or up to 8 metres with prior approval.

Which option fits your home?

Side or side-return extension

Uses the strip of land beside the house, often a passage or driveway. Under permitted development a side extension can be up to half the width of the original house and no more than 4 metres high. On a terrace with a narrow side return, it can widen a galley kitchen considerably without eating into the garden.

Rear kitchen-diner extension

The usual layout: a 3–6 metre extension across all or part of the back wall, with the old rear wall replaced by a steel beam so the new and existing rooms become one space. Roof lights or a lantern bring daylight into the middle of the house, and bifold or sliding doors open onto the garden.

How much should you budget in Staffordshire?

Prices in Staffordshire match the rest of our area: £28,000–£90,000 depending on size and specification. A 4 m × 5 m rear extension on a semi, with roof lights and bifold doors: usually £40,000–£52,000.

Questions about single-storey extensions in Staffordshire

Do I need to tell my neighbours about an extension?

You don't need their permission for permitted development, but you will usually need to involve them. Under the prior approval route the council writes to adjoining neighbours and gives them 21 days to comment. If the build is on the boundary or the foundations are deep and close to their house, the Party Wall Act requires formal written notice. A friendly conversation before any notice arrives usually makes everything smoother.
