Single-storey extensions in Wolverhampton

Planning your single-storey extension in Wolverhampton

City of Wolverhampton Council is the planning authority for Wolverhampton. 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.

Detached houses get a little more room: 4 metres as standard, or up to 8 metres with prior approval.
Every extension needs Building Regulations approval, even when planning permission isn't required.
A lawful development certificate from City of Wolverhampton Council confirms in writing that a permitted development extension is lawful, which helps when you sell.

Which options suit homes in Wolverhampton?

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.

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 Wolverhampton?

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

Single-storey extensions in Wolverhampton: common questions

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.

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.

Will I need permission from the council in Wolverhampton?

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