Single-storey extensions in Yardley

What should you know before starting in Yardley?

Birmingham City Council is the planning authority for Yardley. If your plans need permission, apply early: householder applications have an eight-week target for a decision. Building Regulations approval and inspections run alongside the build.

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.
If you're building over or near a public sewer, the sewerage company has to agree before the foundations go in.

Options to consider in Yardley

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.

How much should you budget in Yardley?

For a home in Yardley, our guide range is £28,000–£90,000 depending on size and specification. A 4 m × 5 m rear extension on a semi, with roof lights and bifold doors: usually £40,000–£52,000.

Guide prices for single-storey extensions
Option	Guide price	Good to know
Small rear or side extension (10–15 m²)	£28,000 – £40,000	Utility, WC or a modest kitchen extension
Rear kitchen-diner extension (18–25 m²)	£38,000 – £58,000	The glazing spec moves it within the range
Wrap-around or large extension (30 m²+)	£58,000 – £90,000	More steel and roof, and normally a planning application

Guide ranges include VAT where it applies. Access, parking and the state of what's there now can move the price — the survey settles it.

Single-storey extensions in Yardley: common questions

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 Yardley do you work in?

We cover B25, B26 and the streets around them. If you're on the edge of Yardley, neighbouring Stechford 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 Yardley?

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