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 Epsom?
In Epsom, a bungalow loft conversion typically costs £50,500–£89,500 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate). Building costs in the South East run about 12% above the UK average, and the figures for Epsom are adjusted to reflect that. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| A typical bungalow conversion with dormers | £50,500–£89,500 |
| Higher specification | £89,500–£112,000 |
The biggest cost drivers are:
- Bathrooms
- Whether the roof is raised
- Staircase position within the bungalow
- 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 Epsom?
Whether you need planning permission depends on your house and its location 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.

Do you build bungalow loft conversions in Epsom?
Yes. We build bungalow loft conversions across Epsom, including postcodes KT17 and KT19. Every project starts with a free home visit.
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.
Does it need planning permission?
Rear dormers are often permitted development; front dormers, roof raises and work in conservation areas need an application.

For a single new floor, escape windows may be acceptable instead of a fully protected stairway. Building control confirms the approach.
