Single-storey extensions in Sheldon

Single-storey extensions in Sheldon: approvals and local details

In Sheldon, Birmingham City Council decides planning questions. We check permitted development limits and any local restrictions at the survey, then deal with the Building Regulations side so you receive a completion certificate when the work is signed off.

Detached houses get a little more room: 4 metres as standard, or up to 8 metres with prior approval.
Under permitted development, a rear extension on a semi or terrace can usually project 3 metres from the original back wall, or 6 metres through the prior approval route.
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 Sheldon

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.

How much should you budget in Sheldon?

Expect to budget between £28,000 and £90,000 depending on size and specification in Sheldon. A 4 m × 5 m rear extension on a semi, with roof lights and bifold doors: typically £40,000–£52,000.

Before you book in Sheldon

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.

Which postcodes in Sheldon do you work in?

We cover B26 and the streets around them. If you're on the edge of Sheldon, neighbouring Yardley and Olton are covered too.

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.

Will I need permission from the council in Sheldon?

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