Single-storey extensions in Bartley Green

Before your single-storey extension in Bartley Green

Before work starts on your single-storey extension in Bartley Green, two things get checked: whether planning permission from Birmingham City Council is needed, and how Building Regulations approval will be obtained. If you share a wall with a neighbour, the Party Wall etc. Act 1996 may apply as well.

A lawful development certificate from Birmingham City Council confirms in writing that a permitted development extension is lawful, which helps when you sell.
Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.
Every extension needs Building Regulations approval, even when planning permission isn't required.

Choices to weigh up in Bartley Green

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 Bartley Green?

For a home in Bartley Green, our guide range is £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.

Before you book in Bartley Green

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 Bartley Green?

Yes. Bartley Green (B32) 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.

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.

Does Birmingham City Council need to approve my single-storey extension?

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