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 Sittingbourne?
In Sittingbourne, a bungalow loft conversion typically costs £50,500–£89,500 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate). We start from a UK-wide guide and adjust it for the South East, where labour and materials are typically about 12% above average. 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:
- Whether the roof is raised
- Fire escape design
- Staircase position within the bungalow
- Number and size of dormers
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 Sittingbourne?
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.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
We check this for your address before design work starts, so there are no surprises later.

Planning matters in Sittingbourne go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
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.
