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 Portadown?
In Portadown, 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 Portadown?
Approvals for a bungalow loft conversion in Portadown 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

Questions about bungalow loft conversions in Portadown
Can every bungalow have a loft conversion?
Most can, but low-pitched roofs may need dormers or a roof raise to give enough head height. We check the structure at the survey.
Where does the staircase go?
Usually from the hallway or a bedroom that becomes a landing. Losing a little ground-floor space is normal.
Will the bungalow still be valued as a bungalow?
It becomes a chalet bungalow. Whether that adds value depends on local demand.
