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 Irlam?
In Irlam, a bungalow loft conversion typically costs £42,500–£75,000 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate). We start from a UK-wide guide and adjust it for the North West, where labour and materials are typically about 6% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| A typical bungalow conversion with dormers | £42,500–£75,000 |
| Higher specification | £75,000–£94,000 |
The main things that change the cost:
- Number and size of dormers
- Staircase position within the bungalow
- Bathrooms
- Fire escape design
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 Irlam?
Approvals for a bungalow loft conversion in Irlam follow the rules for England. In England rear dormers on a bungalow are often permitted development within the 50 cubic metre volume limit. Front dormers, roof raises and conservation-area work need planning permission.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
