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.

In Holyhead, a bungalow loft conversion typically costs £41,500–£73,500 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate).

Approvals for a bungalow loft conversion in Holyhead follow the rules for Wales. In Wales rear dormers may be permitted development within volume limits; front dormers and roof raises need planning permission.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, 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.
