When a porch extension makes sense
- Front doors that open straight into a living room
- Homes wanting better kerb appeal
- Busy hallways with no storage
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.

Working in Caerphilly
Our survey diary covers Caerphilly, including CF83. The same team covers Risca (6 miles), Pontypridd (6 miles), Gelligaer (6 miles), Blackwood (6 miles), all within easy reach.
Just over the South Glamorgan border, Cardiff is about 7 miles away. In Wales, terraced houses with rear offshoots are common in the towns, while detached houses and bungalows dominate in rural areas.
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.
In a conservation area, national park, National Landscape or World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
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).
