Single-storey extensions in Hall Green

What should you know before starting in Hall Green?

Before work starts on your single-storey extension in Hall 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.

Detached houses get a little more room: 4 metres as standard, or up to 8 metres with prior approval.
Every extension needs Building Regulations approval, even when planning permission isn't required.
Most of the build happens outside, so the kitchen is usually only out of action for one to three weeks near the end.

Which options suit homes in Hall Green?

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.

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.

What does your single-storey extension cost in Hall Green?

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.

Your questions answered

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.

How do I book a survey in Hall Green?

Send the form on this page, use the guide-price tool or call 0800 088 6248 free. We'll ask a few questions about your single-storey extension and arrange a time to visit.

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 Hall Green?

Usually building control, and sometimes planning. Birmingham City Council is the planning authority for Hall 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.
