Single-storey extensions in Binley

Planning your single-storey extension in Binley

Planning applications and lawful development certificates for Binley go to Coventry City Council. Many single-storey extensions fall under permitted development, but not every house keeps those rights — conditions on newer estates, conservation areas and Article 4 directions can remove them. The structural work also needs Building Regulations approval, through the council's building control team or a registered building control approver.

If you're building over or near a public sewer, the sewerage company has to agree before the foundations go in.
A lawful development certificate from Coventry City Council confirms in writing that a permitted development extension is lawful, which helps when you sell.
Most of the build happens outside, so the kitchen is usually only out of action for one to three weeks near the end.

Choices to weigh up in Binley

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.

How much should you budget in Binley?

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

If you need a planning application or a lawful development certificate, councils aim to decide within 8 weeks. Glazing and steel are ordered early so they arrive when the shell is ready, which keeps the build from stalling halfway.
