Covering Cwmbran
Cwmbran sits 5 miles north of Newport, with Pontypool 3 miles to the north and Newport 5 miles to the south.
Homes in Gwent
Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.
What do you get with a house-to-flat conversion?
We assess the house against the council’s policies on flat sizes, parking, bins and cycle storage before any design work, then design layouts to the space standards your council uses. On site the critical work is fire separation, sound insulation between floors, separate services and meters, and protected escape routes.
- Planning and building regulations checks under Welsh rules
- Feasibility check against local planning policy
- Planning application and layouts to space standards
How much does a house-to-flat conversion cost in Cwmbran?
Typical ranges for house-to-flat conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
Priced on survey.
Do you need permission for a house-to-flat conversion in Cwmbran?
In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.
This needs full planning permission from your council in Wales.
What can change the price or programme?
- Sound insulation between flats is tested on completion.
- Mortgage lenders and freehold arrangements need early legal advice.
How does the project run?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
