Single-storey extensions in Coventry

Single-storey extensions in Coventry: approvals and local details

Before work starts on your single-storey extension in Coventry, two things get checked: whether planning permission from Coventry 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.

Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.
A lawful development certificate from Coventry City Council confirms in writing that a permitted development extension is lawful, which helps when you sell.
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.

Which option fits your home?

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.

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 Coventry?

Expect to budget between £28,000 and £90,000 depending on size and specification in Coventry. 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 Coventry: 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 Coventry?

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.

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.

Will I need permission from the council in Coventry?

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