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 Keynsham?
In Keynsham, a porch typically costs £6,750–£16,500 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). Prices in the South West sit near the national average for this kind of work, and the range for Keynsham reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a porch in Keynsham?
The approval route for Keynsham 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

Questions about porches in Keynsham

In Keynsham, a porch typically costs £6,750–£16,500 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). Your fixed price depends on the survey and drawings.
Can you move the gas or electric meter?

Who approves a porch in Keynsham?
Planning matters in Keynsham go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
How long does it take?
Usually 2 to 4 weeks on site.
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.
