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 Southgate?
In Southgate, a porch typically costs £8,500–£21,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). Building costs in London run about 30% above the UK average, and the figures for Southgate are adjusted to reflect that. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| From a 3 m² porch to a small front extension | £8,500–£21,000 |
| Higher specification | £21,000–£26,000 |
The main things that change the cost:
- Moving meters, drains or the doorbell and lighting
- Brick matching
- Front door specification
- Size and roof style
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 Southgate?
Before anything is built in Southgate, 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.
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.

We source matching bricks and tiles where possible, or suggest a deliberate contrast.
