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 Crawley?
In Crawley, a porch typically costs £7,250–£18,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). Building costs in the South East run about 12% above the UK average, and the figures for Crawley 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 | £7,250–£18,000 |
| Higher specification | £18,000–£22,500 |
The biggest cost drivers are:
- Front door specification
- Brick matching
- Size and roof style
- Moving meters, drains or the doorbell and lighting
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 Crawley?
Approvals for a porch in Crawley 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.
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.
