Working in Brierley Hill
Site visits are available across Brierley Hill (B64, DY2, DY5, DY6, DY8). Neighbouring towns we cover include Stourbridge (2 miles), Dudley (2 miles), Kingswinford (2 miles), Halesowen (4 miles).
Just over the Worcestershire border, Kidderminster is about 8 miles away. Across the West Midlands, brick-built semis with long gardens are common, so single-storey and two-storey rear extensions are popular choices.
Planning rules that apply in Brierley Hill
In England a single-storey side extension can be permitted development if it is no more than 4 m high and no wider than half the width of the original house. Two-storey side extensions, and any side extension on designated land such as a conservation area, need a householder planning application.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).
What we take care of
- Windows, doors and finishes to match
- Foundations near boundaries and any drains
- Structure, roof tied into the house
- New openings through the side wall
Our process, step by step
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
Design and approvals
We draw the design, agree it with you and handle planning or permitted development checks and building regulations.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
Your questions about a side extension in Brierley Hill
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Brierley Hill, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Brierley Hill?
Yes. We cover Brierley Hill and the surrounding parts of West Midlands. Site visits are free and there is no obligation.
Will my neighbours in Brierley Hill be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Can I build over my driveway?
Yes, if the foundations work and you keep any parking the council requires. Drains and services under drives are common, so we check before design.
How close to the boundary can I build?
It depends on height. In England, within 2 m of a boundary the eaves must not exceed 3 m under permitted development. Building on the boundary is possible but brings party wall and maintenance access issues we plan for.
