Homes in Gwent
Housing in Wales ranges from terraced streets in the valleys and older industrial towns to stone-built homes in rural areas and modern estates around the cities.
What is included in a new-build home in Caerphilly?
We can take a plot from feasibility through planning, detailed design, building regulations, construction and handover, or build to a design and planning permission you already have. The structure can be traditional masonry or timber frame, and we work to the energy and ventilation rules that apply to new homes in each nation.
- Planning and building regulations checks under Welsh rules
- Design, planning application and discharge of conditions
- Superstructure, roof, windows and external finishes

| Standard specification | £2,000 to £2,500 per m² |

Planning and building rules in Caerphilly
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?
- Most lenders want a structural warranty or architect’s certificate on a new home.
- Planning conditions often need discharging before work starts.
How does the project run?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Site visit. We walk the plot or existing house, look at access, levels, services and boundaries, and talk through what could be built.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
