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 Derby?
In Derby, a bungalow loft conversion typically costs £43,000–£76,000 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate). The guide for Derby reflects typical costs in the East Midlands, roughly 5% below the UK-wide figure. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| A typical bungalow conversion with dormers | £43,000–£76,000 |
| Higher specification | £76,000–£95,000 |
The biggest cost drivers are:
- Staircase position within the bungalow
- Whether the roof is raised
- Number and size of dormers
- Bathrooms
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 Derby?
The approval route for Derby is set by planning law in 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.

Questions about bungalow loft conversions in Derby
Who approves a bungalow loft conversion in Derby?
Planning matters in Derby go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
Will the bungalow still be valued as a bungalow?
It becomes a chalet bungalow. Whether that adds value depends on local demand.
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.
