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 Plymouth?
In Plymouth, 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 Plymouth reflects that. 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 biggest cost drivers are:
- Size and roof style
- Whether building regulations apply
- Front door specification
- Moving meters, drains or the doorbell and lighting
Use the guide price tool to see how size and specification change the figure, then ask for a written, itemised quote.
Do you need planning permission for a porch in Plymouth?
Approvals for a porch in Plymouth follow the rules for 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

From survey to sign-off, the job normally involves:
- Electrics for lighting
- Plastering and decoration
- Foundations and brickwork
- Design to match the house
- Front door and windows
- Roof and guttering
How long does it take?
Build time is typically 2 to 4 weeks on site. Before that, surveys, drawings and approvals usually take 6 to 12 weeks, longer if the council asks for changes.
Building in Plymouth
In parts of the South West, protected landscapes and conservation areas shape what can be built, so materials and roof forms are chosen carefully.
From PL2 outwards, we take on projects throughout Plymouth and the surrounding parts of Devon.

Questions about porches in Plymouth
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.
