What is a hip-to-gable loft conversion?
A hip-to-gable loft conversion replaces the sloping side (the hip) of a semi-detached or detached roof with a vertical gable wall. This extends the ridge and creates enough space for a staircase and a full-size room, usually combined with a rear dormer.
How much does a hip-to-gable loft conversion cost in Craigavon?
In Craigavon, a hip-to-gable loft conversion typically costs £47,500–£67,000 for a hip-to-gable with rear dormer, including VAT at 20% (standard rate). Building costs in Northern Ireland run about 14% below the UK average, and the figures for Craigavon are adjusted to reflect that. Design, structural calculations and council fees are extra.

|---|---|
| A hip-to-gable with rear dormer | £47,500–£67,000 |

Your quote will depend mainly on:
- Scaffolding to three sides
- Staircase design
- Size of the rear dormer
- Bathroom and plumbing
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 hip-to-gable loft conversion in Craigavon?
Whether you need planning permission depends on your house and its location in Northern Ireland. In Northern Ireland roof enlargements must be set back from the verges to be permitted development, so a hip-to-gable conversion usually needs planning permission.
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.

Yes. We match the existing finish, whether brick, render or pebbledash.
