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 Bristol?
In Bristol, a porch typically costs £6,750–£16,500 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). Building costs in the South West are close to the UK average, so the figures for Bristol are close to our national guide. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| From a 3 m² porch to a small front extension | £6,750–£16,500 |
| Higher specification | £16,500–£20,500 |
The main things that change the cost:
- Moving meters, drains or the doorbell and lighting
- Front door specification
- Whether building regulations apply
- Size and roof style
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 Bristol?
The approval route for Bristol 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.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

Building in Bristol
The South West mixes stone and render cottages with post-war and newer estates, and local materials matter more here when matching an extension.
We cover the whole of Bristol.

Questions about porches in Bristol
How much does a porch cost in Bristol?
In Bristol, 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.
Do you build porches in Bristol?
Yes. We build porches across Bristol, including postcodes BS0, BS1, BS10, BS11 and BS13. Every project starts with a free home visit.
Can I have a toilet in my porch?
A downstairs toilet usually needs a larger front extension, a drainage connection and building regulations approval.
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.
