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 Birmingham?
In Birmingham, a porch typically costs £6,250–£15,500 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). Building costs in the West Midlands are close to the UK average, so the figures for Birmingham 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 | £6,250–£15,500 |
| Higher specification | £15,500–£19,500 |
The main things that change the cost:
- Moving meters, drains or the doorbell and lighting
- Front door specification
- Brick matching
- Whether building regulations apply
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 Birmingham?
Before anything is built in Birmingham, we confirm which approvals apply 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.
We check this for your address before design work starts, so there are no surprises later.

How long does it take?
Build time is typically 2 to 4 weeks on site. Design and approvals come first and typically take 6 to 12 weeks, depending on the approval route.

Questions about porches in Birmingham
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.
How long does it take?
Usually 2 to 4 weeks on site.
