Single-storey extensions in Droitwich Spa

Single-storey extensions in Droitwich Spa: approvals and local details

Wychavon District Council is the planning authority for Droitwich Spa. 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.
Wide glazed doors and roof lights make the biggest difference to how bright the new room feels, and to the final price.
A lawful development certificate from Wychavon District Council confirms in writing that a permitted development extension is lawful, which helps when you sell.

Which options suit homes in Droitwich Spa?

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 Droitwich Spa?

Prices in Droitwich Spa match the rest of our area: £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 Wychavon District Council need to approve my single-storey extension?

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