Covering Hereford
Alongside Hereford, we also cover Ross-on-Wye (12 miles to the south-east), Leominster and Ledbury.
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 is included in a basement conversion in Hereford?
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.
- Damp and structural survey
- Lightwells and windows for daylight and escape
- Ventilation, heating and electrics
What will a basement conversion cost?
Indicative costs for basement and cellar conversions. London and the South East usually sit towards the top of each range.
| Basement and cellar conversions | Guide price incl. VAT |
|---|---|
| Existing cellar conversion | £1,900 to £3,000 per m² |
| New basement excavation | £4,200 to £6,600 per m² |
Planning and building rules in Hereford
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.
What should I think about before starting?
- Groundwater levels drive the waterproofing design and cost.
- New basements nearly always involve the Party Wall Act in England and Wales.
What are the steps?
- 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.
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.
Will my neighbours be affected?
New basements usually need party wall agreements. We handle the notices and surveyors.
