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 Carrickfergus?
In Carrickfergus, 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 Carrickfergus are adjusted to reflect that. Design, structural calculations and council fees are extra.

Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a bungalow loft conversion in Carrickfergus?
Approvals for a bungalow loft conversion in Carrickfergus follow the rules for 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.
