What is a porch?
A porch is a small extension built around the front door, giving a lobby for coats and shoes and stopping draughts reaching the hall. Most are brick with a pitched tiled roof to match the house, though glazed and timber porches are also common.
How much does a porch cost in Caerphilly?
In Caerphilly, a porch typically costs £6,000–£14,500 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate).

Do you need planning permission for a porch in Caerphilly?
Here is how the rules work for a porch in Wales. In Wales small porches are generally permitted development within similar limits: about 3 square metres of ground area, no more than 3 metres high and set back from a road boundary.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
