Single-storey extensions in Alvechurch

Single-storey extensions in Alvechurch: approvals and local details

Planning applications and lawful development certificates for Alvechurch 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.

A lawful development certificate from Bromsgrove District Council confirms in writing that a permitted development extension is lawful, which helps when you sell.
Wide glazed doors and roof lights make the biggest difference to how bright the new room feels, and to the final price.
Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.

Which option fits your home?

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.

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.

Your questions answered

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.

Which postcodes in Alvechurch do you work in?

We cover B48 and the streets around them. If you're on the edge of Alvechurch, neighbouring Redditch and Longbridge are covered too.

What guarantees come with the extension?

Windows, doors, roof lights and roofing membranes come with manufacturers' guarantees, and the terms for each product are set out in your quote. Building control's completion certificate confirms the work met Building Regulations when inspected. If anything in our workmanship isn't right after handover, call us and we'll come back and look at it. Ask us for current insurance details with your quote.

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 Alvechurch; Building Regulations approval comes from its building control team or a registered building control approver. We'll tell you which applies after the survey.
