Single-storey extensions in Sedgley

Before your single-storey extension in Sedgley

Planning applications and lawful development certificates for Sedgley go to Dudley Council. 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.

Detached houses get a little more room: 4 metres as standard, or up to 8 metres with prior approval.
If you're building over or near a public sewer, the sewerage company has to agree before the foundations go in.
Most of the build happens outside, so the kitchen is usually only out of action for one to three weeks near the end.

Options to consider in Sedgley

Wrap-around extension

Combines a side and rear extension into an L shape, giving the largest ground-floor gain. Because it extends both sideways and rearwards, a wrap-around normally needs a householder planning application rather than relying on permitted development. Expect more steelwork and a more involved roof where the two sections meet.

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.

Guide prices for Sedgley

Guide prices start at £28,000 and run to £90,000 depending on size and specification. A 4 m × 5 m rear extension on a semi, with roof lights and bifold doors: around £40,000–£52,000.

Before you book in Sedgley

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.

Do you cover Sedgley?

Yes. Sedgley (DY3) is about 6 miles from our West Bromwich base and inside the area we cover. Call 0800 088 6248 or send the form on this page to book a free survey.

How long does a single-storey extension take?

Allow 8–12 weeks on site for most single-storey extensions, plus time beforehand for drawings and approvals. If you need a planning application or a lawful development certificate, councils aim to decide within 8 weeks. Glazing and steel are ordered early so they arrive when the shell is ready, which keeps the build from stalling halfway.

Will I need permission from the council in Sedgley?

Usually building control, and sometimes planning. Dudley Council is the planning authority for Sedgley; Building Regulations approval comes from its building control team or a registered building control approver. We'll tell you which applies after the survey.
