What is a bungalow loft conversion?
A bungalow loft conversion uses the large roof space of a bungalow to add bedrooms and a bathroom, turning it into a chalet bungalow. Dormers at the front, rear or both create headroom; some projects raise the roof entirely.
How much does a bungalow loft conversion cost in Larne?
In Larne, a bungalow loft conversion typically costs £38,500–£69,000 for a typical bungalow conversion with dormers, 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 bungalow loft conversion in Larne?
Whether you need planning permission depends on your house and its location in Northern Ireland. In Northern Ireland rear dormers on a bungalow can be permitted development if they do not face a road and keep the required set-backs from the ridge, eaves and verges. Front dormers and roof raises need 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.
