Single-storey extensions in Balsall Common

Single-storey extensions in Balsall Common: approvals and local details

Solihull Council is the planning authority for Balsall Common. 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.

A lawful development certificate from Solihull Council confirms in writing that a permitted development extension is lawful, which helps when you sell.
Every extension needs Building Regulations approval, even when planning permission isn't required.
If you're building over or near a public sewer, the sewerage company has to agree before the foundations go in.

Which option fits your home?

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.

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.

How much should you budget in Balsall Common?

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

Single-storey extensions in Balsall Common: common questions

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.

How do I book a survey in Balsall Common?

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.

Who approves single-storey extensions in Balsall Common?

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