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 Mendip?
In Mendip, a bungalow loft conversion typically costs £46,000–£81,500 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate). Prices in the South West sit near the national average for this kind of work, and the range for Mendip reflects that. Design, structural calculations and council fees are extra.

Your quote will depend mainly on:
- Staircase position within the bungalow
- Fire escape design
- Finishes
- Bathrooms
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 Mendip?
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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

Questions about bungalow loft conversions in Mendip
Does it need planning permission?
Rear dormers are often permitted development; front dormers, roof raises and work in conservation areas need an application.
Will the bungalow still be valued as a bungalow?
It becomes a chalet bungalow. Whether that adds value depends on local demand.
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.
