Working in Penarth
Our survey diary covers Penarth, including CF64. Neighbouring towns we cover include Cardiff (3 miles), Barry (5 miles), Cowbridge (12 miles).
Caerphilly, in Mid Glamorgan, is roughly 10 miles from Penarth 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.
Will the council need to approve it?
In Wales small porches are usually permitted development within size and boundary limits similar to England's. We check the current Welsh limits for your address.
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.
The Party Wall etc. Act 1996 applies in Wales as in England: notice must be served before work to a shared wall, building on the boundary, or excavating close to a neighbour's foundations.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).
How much does a porch extension cost in Penarth?
Labour and material costs vary across the UK, so for Penarth we use our Wales factor (×0.93). The ranges include VAT and exclude design, structural and council fees.
