Single-storey extensions in Worcestershire

Single-storey extensions in Worcestershire: approvals and local details

In Worcestershire, the district or borough council for your town 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.

Detached houses get a little more room: 4 metres as standard, or up to 8 metres with prior approval.
Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.
Every extension needs Building Regulations approval, even when planning permission isn't required.

Which options suit homes in Worcestershire?

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.

Wrap-around extension

Combines a side and rear extension into an L shape, giving the largest ground-floor gain. Because it extends both sideways and rearwards, a wrap-around normally needs a householder planning application rather than relying on permitted development. Expect more steelwork and a more involved roof where the two sections meet.

How do I book a survey in Worcestershire?

Send the form on this page, use the guide-price tool or call 0800 088 6248 free. We'll ask a few questions about your single-storey extension and arrange a time to visit.

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 the council need to approve my single-storey extension?

Usually building control, and sometimes planning. the district or borough council for your town is the planning authority for Worcestershire; Building Regulations approval comes from its building control team or a registered building control approver. We'll tell you which applies after the survey.
