Covering Wednesfield
Wednesfield sits 11 miles north-west of Birmingham, with Willenhall 1 miles to the south-east and Wolverhampton 2 miles to the south-west.
Homes in the West Midlands
The West Midlands has a large stock of 1930s semis and Victorian terraces in red brick, so matching brick and roof tiles is often the key to an extension that looks original.
What goes into a basement conversion?
Everything below ground depends on keeping water out. We design the waterproofing system (usually a cavity drain membrane with a pump, or tanking) to the relevant British Standard guidance, then add insulation, ventilation, light and an escape route. New basements involve underpinning and a party wall process and are designed with a structural engineer.
- Waterproofing design and installation
- Underpinning or lowering the floor where needed
- Ventilation, heating and electrics

Planning and building rules in Wednesfield
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
Converting an existing cellar with no external changes usually does not need planning permission in England. Digging a new basement or adding a lightwell often does, and many councils have basement policies.
What can affect a basement conversion?
- New basements nearly always involve the Party Wall Act in England and Wales.
- Headroom of about 2.1 m or more is needed, which may mean lowering the floor.
What happens after I enquire?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- 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.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Basement and cellar conversions: common questions
Does a cellar conversion need planning permission?
Usually not if nothing changes outside. New basements and lightwells often do.
How long does it take?
About 6 to 12 weeks for a cellar conversion and 16 to 30 weeks for a new basement.
Can you visit a house in Wednesfield 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.
