Single-storey extensions in Gornal

Planning your single-storey extension in Gornal

Dudley Council is the planning authority for Gornal. If your plans need permission, apply early: householder applications have an eight-week target for a decision. Building Regulations approval and inspections run alongside the build.

Most of the build happens outside, so the kitchen is usually only out of action for one to three weeks near the end.
Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.
A lawful development certificate from Dudley Council confirms in writing that a permitted development extension is lawful, which helps when you sell.

Options to consider in Gornal

Utility, WC or boot-room extension

A smaller extension of 6–12 m² can take the washing machine, coats and a downstairs toilet out of the kitchen. Adding a WC means a new waste connection, so the position of the existing drains often decides the layout. It's a cost-effective way to free up the main rooms without a large build.

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.

Single-storey extensions in Gornal: common questions

What should I prepare before the survey?

Think about how you want to use the new space, and gather anything you have about the house: old plans, deeds showing boundaries, approvals for any earlier extension, and where you think the drains run. Photos of extensions you like help us price glazing and finishes accurately. If you're in a conservation area or on a newer estate, mention it, as it can affect permitted development.

Do you cover Gornal?

Yes. Gornal (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.

Who approves single-storey extensions in Gornal?

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