Included in a typical project
- Design to suit the house style
- Foundations and drainage for rainwater
- Brick, render or oak frame walls
- Planning check against the porch limits
- Tiled, slate or flat roof
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.
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.
The planning position for a specific Gwynedd address depends on its history and any designations, which is why we check it at the first visit.
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.
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).

Towns we cover in Gwynedd include Bangor, Gwynedd, Caernarfon, Holyhead, Llangefni. 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.
