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 Boston?
In Boston, a bungalow loft conversion typically costs £43,000–£76,000 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 East Midlands, where labour and materials are typically about 5% below average. 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 main things that change the cost:
- Bathrooms
- Number and size of dormers
- Finishes
- Fire escape design
Use the guide price tool to see how size and specification change the figure, then ask for a written, itemised quote.
Do you need planning permission for a bungalow loft conversion in Boston?
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.
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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
From survey to sign-off, the job normally involves:
- Bathroom installation
- Insulation, electrics, plumbing and plastering
- Building control sign-off
- Drawings and structural calculations
- Fire-safe escape windows or route
- Dormers or a raised roof
How long does it take?
Expect 8 to 14 weeks on site. Before that, surveys, drawings and approvals usually take 3 to 4 months, longer if the council asks for changes.

Questions about bungalow loft conversions in Boston
Where does the staircase go?
Usually from the hallway or a bedroom that becomes a landing. Losing a little ground-floor space is normal.
Is fire escape easier in a bungalow?
For a single new floor, escape windows may be acceptable instead of a fully protected stairway. Building control confirms the approach.
