Single-storey extensions in Brownhills

Single-storey extensions in Brownhills: approvals and local details

Walsall Council is the planning authority for Brownhills. 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.

Wide glazed doors and roof lights make the biggest difference to how bright the new room feels, and to the final price.
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.

Choices to weigh up in Brownhills

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.

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.

How much should you budget in Brownhills?

For a home in Brownhills, 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.

What should I prepare before the survey?

Think about how you want to use the new space, and gather anything you have about the house: old plans, deeds showing boundaries, approvals for any earlier extension, and where you think the drains run. Photos of extensions you like help us price glazing and finishes accurately. If you're in a conservation area or on a newer estate, mention it, as it can affect permitted development.

Does Walsall Council need to approve my single-storey extension?

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