Single-storey extensions in Allesley

Single-storey extensions in Allesley: approvals and local details

Before work starts on your single-storey extension in Allesley, 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.

If you're building over or near a public sewer, the sewerage company has to agree before the foundations go in.
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.
A lawful development certificate from Coventry City Council confirms in writing that a permitted development extension is lawful, which helps when you sell.

Which option fits your home?

Flat roof or pitched roof

Flat roofs, usually GRP fibreglass or EPDM rubber, keep the height down near boundaries and suit roof lanterns. Pitched or lean-to roofs with tiles to match the house look more traditional and shed rain faster, but need more height. The choice affects permitted development limits, cost, and how much light reaches the existing rooms.

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 Allesley?

For a home in Allesley, 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.
