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 Gwynedd?
In Gwynedd, a porch typically costs £6,000–£14,500 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). That range is adjusted for Wales, where domestic building work typically costs around 8% below the national average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| From a 3 m² porch to a small front extension | £6,000–£14,500 |
| Higher specification | £14,500–£18,000 |
The main things that change the cost:
- Size and roof style
- Brick matching
- Whether building regulations apply
- Moving meters, drains or the doorbell and lighting

Do you need planning permission for a porch in Gwynedd?
The approval route for Gwynedd is set by planning law 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.
We check this for your address before design work starts, so there are no surprises later.
