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.

Your quote will depend mainly on:
- Brick matching

- Whether building regulations apply
- Size and roof style
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a porch in Farnworth?
The approval route for Farnworth is set by planning law in England. In England a porch is permitted development if its ground floor area is no more than 3 square metres, no part is over 3 metres high and it is at least 2 metres from a boundary next to a road.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
We check this for your address before design work starts, so there are no surprises later.

A downstairs toilet usually needs a larger front extension, a drainage connection and building regulations approval.

Does a porch need building regulations?
In England and Wales a ground-level porch under 30 square metres is usually exempt if the front door stays in place and the glazing meets safety standards. In Scotland the exemption is much smaller (around 8 square metres, with no new opening into the house). If the front door is removed, approval is needed. We check this for your design.
