What we take care of
- Structural calculations for beams, lintels and foundations
- Inspection bookings throughout the build
- Submission to the council or a registered building control approver
- Energy and glazing checks, including whole-house calculations if needed
- Completion certificate on sign-off
Building regulations approval and planning permission are separate. A design can have planning consent and still need changes to meet the regulations, which is why we draw for both together.
Working in Gelligaer
We cover Gelligaer and the postcode districts CF46, CF82. Neighbouring towns we cover include Blackwood (2 miles), Pontypridd (6 miles), Caerphilly (6 miles), Risca (8 miles).
Ebbw Vale, in Gwent, is roughly 8 miles from Gelligaer and also on our list. Welsh housing ranges from stone terraces in the valleys to render-and-slate houses and modern estates, and the Welsh planning rules differ from England's in several places.
Planning and approvals in Gelligaer
Building regulations approval is separate from planning. Wales has its own building regulations and approved documents; the council or a registered building control approver checks the plans, inspects the work and issues a completion certificate.
Homes in conservation areas, national parks, National Landscapes (AONBs) and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
Building over or within 3 m of a public sewer needs the water company's consent before the foundations go in.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

Questions answered
Will my neighbours in Gelligaer be involved?
If a planning application is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Do you cover all of Gelligaer?
Yes. We cover Gelligaer and the surrounding parts of Mid Glamorgan. Site visits are free and there is no obligation.
Do I need building regulations approval in Gelligaer?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Who are building control?
Either your local council’s building control team or a registered building control approver. Both inspect the work and issue the completion certificate.
Full plans or building notice?
A full plans application gets the drawings checked before work starts, which we usually recommend for extensions. A building notice is quicker to submit but carries more risk if something needs changing on site.
