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 Altrincham?
In Altrincham, a bungalow loft conversion typically costs £42,500–£75,000 for a typical bungalow conversion with dormers, including VAT at 20% (standard rate).

Do you need planning permission for a bungalow loft conversion in Altrincham?
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.
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.
What we handle
From survey to sign-off, the job normally involves:
- Fire-safe escape windows or route
- Drawings and structural calculations
- Building control sign-off
- Survey and planning check
- New floor structure and staircase
- Insulation, electrics, plumbing and plastering
How long does it take?
Allow 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.
