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 Caernarfon?
In Caernarfon, a porch typically costs £6,000–£14,500 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate).

A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Do you need planning permission for a porch in Caernarfon?
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.
The Party Wall etc. Act 1996 applies in Wales, so notices must be served before work on a shared wall, on the boundary, or excavation close to a neighbour’s foundations.
We check this for your address before design work starts, so there are no surprises later.
