Single-storey extensions in Cannock

Planning your single-storey extension in Cannock

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

Most of the build happens outside, so the kitchen is usually only out of action for one to three weeks near the end.
Detached houses get a little more room: 4 metres as standard, or up to 8 metres with prior approval.
Wide glazed doors and roof lights make the biggest difference to how bright the new room feels, and to the final price.

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.

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.

How much should you budget in Cannock?

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

Before you book in Cannock

How long does a single-storey extension take?

Allow 8–12 weeks on site for most single-storey extensions, plus time beforehand for drawings and approvals. 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.

Which postcodes in Cannock do you work in?

We cover WS11 and the streets around them. If you're on the edge of Cannock, neighbouring Heath Hayes and Hednesford are covered too.

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.

Does Cannock Chase District Council need to approve my single-storey extension?

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