Single-storey extensions in Olton

What should you know before starting in Olton?

Before work starts on your single-storey extension in Olton, two things get checked: whether planning permission from Solihull 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.

If you're building over or near a public sewer, the sewerage company has to agree before the foundations go in.
Most of the build happens outside, so the kitchen is usually only out of action for one to three weeks near the end.
A lawful development certificate from Solihull Council confirms in writing that a permitted development extension is lawful, which helps when you sell.

Choices to weigh up in Olton

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 Olton do you work in?

We cover B92 and the streets around them. If you're on the edge of Olton, neighbouring Acocks Green and Sheldon are covered too.

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.

Will I need permission from the council in Olton?

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