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 Downpatrick?
In Downpatrick, a bungalow loft conversion typically costs £38,500–£69,000 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate). Building costs in Northern Ireland run about 14% below the UK average, and the figures for Downpatrick are adjusted to reflect that. Design, structural calculations and council fees are extra.

Do you need planning permission for a bungalow loft conversion in Downpatrick?
The approval route for Downpatrick is set by planning law 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.
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.
