Local to Cowbridge
Our survey diary covers Cowbridge, including CF71. Neighbouring towns we cover include Barry (8 miles), Cardiff (12 miles), Penarth (12 miles).
Bridgend, in Mid Glamorgan, is roughly 6 miles from Cowbridge and also on our list. In Wales, terraced houses with rear offshoots are common in the towns, while detached houses and bungalows dominate in rural areas.
Planning rules that apply in Cowbridge
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
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).
What is included
- Planning check against the porch limits
- Foundations and drainage for rainwater
- Brick, render or oak frame walls
- Design to suit the house style
- Tiled, slate or flat roof
- Front door, glazing and electrics
Proportion matters on a porch more than on any other extension, because it is at the front. We match the roof pitch and brick and keep the front door in proportion with the house windows.
