Covering West Bromwich
We work in West Bromwich (B70) and the places around it, including Smethwick, Tipton and Dudley.
Homes in the West Midlands
Across the West Midlands, terraced and semi-detached houses in red brick are typical, along with post-war estates where garage conversions and side extensions are popular.
What do you get with a double-storey extension?
A double-storey extension adds new rooms on both the ground and first floor in one build, typically a larger kitchen or living space downstairs and an extra bedroom or bathroom above. Because the roof and foundations are shared, the cost per square metre is usually lower than a single-storey extension.
- Measured survey, design and planning drawings
- Householder planning application
- Joining the new first floor to the existing landing
What will a double-storey extension cost?
Typical ranges for double-storey extensions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| Double-storey extensions | Guide price incl. VAT |
|---|---|
| Standard specification | £2,400 to £2,900 per m² |
| Good specification | £2,900 to £3,400 per m² |
| High specification | £3,400 to £3,850 per m² |
How is a double-storey extension approved in West Bromwich?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
Two-storey rear extensions can sometimes be permitted development in England (no more than 3 m deep, at least 7 m from the rear boundary, roof pitch to match), but most two-storey and all two-storey side extensions need householder planning permission.
What can affect a double-storey extension?
- Side extensions close to a boundary are often set back or stepped down so they do not create a terraced effect.
- The new roof is tied into the old one, so roof tiles and ridge details need to match.
What happens after I enquire?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
Questions about a double-storey extension in West Bromwich
How long does a two-storey extension take?
Around 14 to 24 weeks on site, plus the planning period before that.
Will we need to move out?
Most people stay. The noisiest stage is when we break through into the existing first floor, which we plan for a short window.
Can you visit a house in West Bromwich to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
