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 Greenford?
In Greenford, a porch typically costs £8,500–£21,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). That range is adjusted for London, where domestic building work typically costs around 30% above the national average. Design, structural calculations and council fees are extra.

|---|---|
| From a 3 m² porch to a small front extension | £8,500–£21,000 |
| Higher specification | £21,000–£26,000 |

Do you need planning permission for a porch in Greenford?
Approvals for a porch in Greenford 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.
