Single-storey extensions in Catshill

What should you know before starting in Catshill?

Planning applications and lawful development certificates for Catshill go to Bromsgrove District Council. Many single-storey extensions fall under permitted development, but not every house keeps those rights — conditions on newer estates, conservation areas and Article 4 directions can remove them. The structural work also needs Building Regulations approval, through the council's building control team or a registered building control approver.

If you're building over or near a public sewer, the sewerage company has to agree before the foundations go in.
Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.
Most of the build happens outside, so the kitchen is usually only out of action for one to three weeks near the end.

Choices to weigh up in Catshill

Side or side-return extension

Uses the strip of land beside the house, often a passage or driveway. Under permitted development a side extension can be up to half the width of the original house and no more than 4 metres high. On a terrace with a narrow side return, it can widen a galley kitchen considerably without eating into the garden.

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.

Your questions answered

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.

How do I book a survey in Catshill?

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.

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.

Will I need permission from the council in Catshill?

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