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 Christchurch?
In Christchurch, 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 Christchurch are close to our national guide. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| A typical bungalow conversion with dormers | £46,000–£81,500 |
| Higher specification | £81,500–£102,000 |
The biggest cost drivers are:
- Fire escape design
- Staircase position within the bungalow
- Number and size of dormers
- Finishes
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 Christchurch?
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 Christchurch
Will the bungalow still be valued as a bungalow?
It becomes a chalet bungalow. Whether that adds value depends on local demand.
Who approves a bungalow loft conversion in Christchurch?
Planning matters in Christchurch go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
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.
