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 Deeside?
In Deeside, a bungalow loft conversion typically costs £41,500–£73,500 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate). We start from a UK-wide guide and adjust it for Wales, where labour and materials are typically about 8% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| A typical bungalow conversion with dormers | £41,500–£73,500 |
| Higher specification | £73,500–£92,000 |
The biggest cost drivers are:
- Bathrooms
- Fire escape design
- Finishes
- Staircase position within the bungalow
A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Do you need planning permission for a bungalow loft conversion in Deeside?
Before anything is built in Deeside, we confirm which approvals apply in Wales. In Wales rear dormers may be permitted development within volume limits; front dormers and roof raises need planning permission.
The Party Wall etc. Act 1996 applies in Wales, so notices must be served before work on a shared wall, on the boundary, or excavation close to a neighbour’s foundations.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
