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 Lisburn?
In Lisburn, a porch typically costs £5,500–£14,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). We start from a UK-wide guide and adjust it for Northern Ireland, where labour and materials are typically about 14% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| From a 3 m² porch to a small front extension | £5,500–£14,000 |
| Higher specification | £14,000–£17,500 |
The biggest cost drivers are:

Do you need planning permission for a porch in Lisburn?
Before anything is built in Lisburn, we confirm which approvals apply in Northern Ireland. In Northern Ireland a porch is permitted development if its ground area is no more than 3 square metres, it is no higher than 3 metres (3.5 metres with a pitched roof) and it is at least 2 metres from a boundary with a road.
In Northern Ireland building control approval comes from the council, usually through a full plans application or a building notice, with inspections during the work and a completion certificate at the end.
We check this for your address before design work starts, so there are no surprises later.
