Single-storey extensions in Rubery

Single-storey extensions in Rubery: approvals and local details

Before work starts on your single-storey extension in Rubery, two things get checked: whether planning permission from Bromsgrove District Council is needed, and how Building Regulations approval will be obtained. If you share a wall with a neighbour, the Party Wall etc. Act 1996 may apply as well.

Wide glazed doors and roof lights make the biggest difference to how bright the new room feels, and to the final price.
Most of the build happens outside, so the kitchen is usually only out of action for one to three weeks near the end.
Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.

Options to consider in Rubery

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.

Which postcodes in Rubery do you work in?

We cover B45 and the streets around them. If you're on the edge of Rubery, neighbouring Longbridge and Northfield are covered too.

How long does a single-storey extension take?

Allow 8–12 weeks on site for most single-storey extensions, plus time beforehand for drawings and approvals. If you need a planning application or a lawful development certificate, councils aim to decide within 8 weeks. Glazing and steel are ordered early so they arrive when the shell is ready, which keeps the build from stalling halfway.

Does Bromsgrove District Council need to approve my single-storey extension?

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