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 Shirley?
In Shirley, a hip-to-gable loft conversion typically costs £53,500–£75,500 for a hip-to-gable with rear dormer, including VAT at 20% (standard rate). Prices in the West Midlands sit near the national average for this kind of work, and the range for Shirley reflects that. Design, structural calculations and council fees are extra.

|---|---|

What moves the price most:
- Gable wall construction and finish
- Staircase design
- Bathroom and plumbing
- 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 Shirley?
Before anything is built in Shirley, we confirm which approvals apply in 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
What we handle
On a typical hip-to-gable loft conversion we handle:
- Drawings and structural calculations
- Roof extension and rear dormer
- Survey and planning check
- Steel beams and floor joists
- Insulation, electrics, plumbing and plastering
- Gable wall built in brick or block and finished to match
How long does it take?
Expect 7 to 10 weeks on site. Before that, surveys, drawings and approvals usually take 6 to 12 weeks, longer if the council asks for changes.
