Single-storey extensions in Kidderminster

What should you know before starting in Kidderminster?

Planning applications and lawful development certificates for Kidderminster go to Wyre Forest 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.
Under permitted development, a rear extension on a semi or terrace can usually project 3 metres from the original back wall, or 6 metres through the prior approval route.
A lawful development certificate from Wyre Forest District Council confirms in writing that a permitted development extension is lawful, which helps when you sell.

Choices to weigh up in Kidderminster

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.

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.

Before you book in Kidderminster

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.

Which postcodes in Kidderminster do you work in?

We cover DY10 and the streets around them. If you're on the edge of Kidderminster, neighbouring Stourport-on-Severn and Bewdley are covered too.

Do I need to tell my neighbours about an extension?

You don't need their permission for permitted development, but you will usually need to involve them. Under the prior approval route the council writes to adjoining neighbours and gives them 21 days to comment. If the build is on the boundary or the foundations are deep and close to their house, the Party Wall Act requires formal written notice. A friendly conversation before any notice arrives usually makes everything smoother.

Will I need permission from the council in Kidderminster?

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