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 Carrickfergus?
In Carrickfergus, a porch typically costs £5,500–£14,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). That range is adjusted for Northern Ireland, where domestic building work typically costs around 14% below the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for a porch in Carrickfergus?
Here is how the rules work for a porch 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.
Northern Ireland has no Party Wall Act. Work on shared walls relies on agreement with the neighbour and common law, so we agree the arrangements in writing before work starts.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.

Questions about porches in Carrickfergus
Who approves a porch in Carrickfergus?
Planning matters in Carrickfergus go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
Will it match my house?
We source matching bricks and tiles where possible, or suggest a deliberate contrast.
Can I have a toilet in my porch?
A downstairs toilet usually needs a larger front extension, a drainage connection and building regulations approval.
Can you move the gas or electric meter?
Meters belong to the supplier or network operator. We coordinate their move as part of the job, which can add time.
