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 Somerset?
In Somerset, a bungalow loft conversion typically costs £46,000–£81,500 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate). Building costs in the South West are close to the UK average, so the figures for Somerset are close to our national guide. Design, structural calculations and council fees are extra.

Do you need planning permission for a bungalow loft conversion in Somerset?
Before anything is built in Somerset, we confirm which approvals apply 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.
We check this for your address before design work starts, so there are no surprises later.

Questions about bungalow loft conversions in Somerset
Where does the staircase go?
Usually from the hallway or a bedroom that becomes a landing. Losing a little ground-floor space is normal.
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.
