Single-storey extensions in Walsgrave

Before your single-storey extension in Walsgrave

Coventry City Council is the planning authority for Walsgrave. 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.

Every extension needs Building Regulations approval, even when planning permission isn't required.
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?

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.

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.

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 Walsgrave?

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