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 Uxbridge?
In Uxbridge, 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 Uxbridge 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 |
Your quote will depend mainly on:
- Whether the roof is raised
- Finishes
- Staircase position within the bungalow
- Number and size of dormers
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 Uxbridge?
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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

How much does a bungalow loft conversion cost in Uxbridge?
In Uxbridge, a bungalow loft conversion typically costs £58,500–£104,000 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate). Your fixed price depends on the survey and drawings.

Do you build bungalow loft conversions in Uxbridge?
Yes. We build bungalow loft conversions across Uxbridge, including postcodes UB8. Every project starts with a free home visit.
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.
