Single-storey extensions in Stafford

Single-storey extensions in Stafford: approvals and local details

In Stafford, Stafford Borough Council decides planning questions. We check permitted development limits and any local restrictions at the survey, then deal with the Building Regulations side so you receive a completion certificate when the work is signed off.

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.
Wide glazed doors and roof lights make the biggest difference to how bright the new room feels, and to the final price.
Every extension needs Building Regulations approval, even when planning permission isn't required.

Options to consider in Stafford

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.

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.

Before you book in Stafford

What guarantees come with the extension?

Windows, doors, roof lights and roofing membranes come with manufacturers' guarantees, and the terms for each product are set out in your quote. Building control's completion certificate confirms the work met Building Regulations when inspected. If anything in our workmanship isn't right after handover, call us and we'll come back and look at it. Ask us for current insurance details with your quote.

Do you cover Stafford?

Yes. Stafford (ST16) is about 20 miles from our West Bromwich base and inside the area we cover. Call 0800 088 6248 or send the form on this page to book a free survey.

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.

Who approves single-storey extensions in Stafford?

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