Single-storey extensions in Great Bridge

Planning your single-storey extension in Great Bridge

Sandwell Council is the planning authority for Great Bridge. 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.

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.
Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.

Options to consider in Great Bridge

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.

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.

Questions about single-storey extensions in Great Bridge

What guarantees come with the extension?

Windows, doors, roof lights and roofing membranes come with manufacturers' guarantees, and the terms for each product are set out in your quote. Building control's completion certificate confirms the work met Building Regulations when inspected. If anything in our workmanship isn't right after handover, call us and we'll come back and look at it. Ask us for current insurance details with your quote.

Do you cover Great Bridge?

Yes. Great Bridge (DY4) is about 2 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.

Can we live at home during the build?

Yes, most families stay at home throughout. For the first several weeks the work is outside and your house is closed off from it. The disruptive part is the break-through, when the back wall comes out and the kitchen may be out of action for one to three weeks. We agree a plan for a temporary sink and cooking space before that stage starts.

Will I need permission from the council in Great Bridge?

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