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 Kensington?
In Kensington, a bungalow loft conversion typically costs £58,500–£104,000 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate). The guide for Kensington reflects typical costs in London, roughly 30% above the UK-wide figure. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| A typical bungalow conversion with dormers | £58,500–£104,000 |
| Higher specification | £104,000–£130,000 |
The biggest cost drivers are:
- Finishes
- Number and size of dormers
- Fire escape design
- Whether the roof is raised
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 Kensington?
Here is how the rules work for a bungalow loft conversion 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.
We check this for your address before design work starts, so there are no surprises later.
