What is a hip-to-gable loft conversion?
A hip-to-gable loft conversion replaces the sloping side (the hip) of a semi-detached or detached roof with a vertical gable wall. This extends the ridge and creates enough space for a staircase and a full-size room, usually combined with a rear dormer.
How much does a hip-to-gable loft conversion cost in West Yorkshire?
In West Yorkshire, a hip-to-gable loft conversion typically costs £51,000–£72,500 for a hip-to-gable with rear dormer, including VAT at 20% (standard rate). We start from a UK-wide guide and adjust it for Yorkshire and the Humber, where labour and materials are typically about 7% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| A hip-to-gable with rear dormer | £51,000–£72,500 |
| Higher specification | £72,500–£90,500 |
Your quote will depend mainly on:
- Size of the rear dormer
- Staircase design
- Gable wall construction and finish
- Scaffolding to three sides
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 hip-to-gable loft conversion in West Yorkshire?
Approvals for a hip-to-gable loft conversion in West Yorkshire follow the rules for England. In England a hip-to-gable conversion is often permitted development within the 50 cubic metre roof volume limit for semi-detached and detached houses, provided the gable does not face a road and the house is not in a conservation area.
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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.

Questions about hip-to-gable loft conversions in West Yorkshire
How long does it take?
Typically 7 to 10 weeks on site.
How much does a hip-to-gable loft conversion cost in West Yorkshire?
In West Yorkshire, a hip-to-gable loft conversion typically costs £51,000–£72,500 for a hip-to-gable with rear dormer, including VAT at 20% (standard rate). Your fixed price depends on the survey and drawings.
Is a hip-to-gable better than a dormer?
On a hipped roof, a dormer alone often leaves too little space for stairs. Combining hip-to-gable with a rear dormer gives the most room.
Who approves a hip-to-gable loft conversion in West Yorkshire?
Planning matters in West Yorkshire go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
Will it look strange next to my neighbour?
On a pair of semis the roofs will no longer match unless your neighbour does the same. Many streets already have several converted roofs.
