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 Peterlee?
In Peterlee, a hip-to-gable loft conversion typically costs £49,500–£70,000 for a hip-to-gable with rear dormer, including VAT at 20% (standard rate). Building costs in the North East run about 10% below the UK average, and the figures for Peterlee are adjusted to reflect that. Design, structural calculations and council fees are extra.

Do you need planning permission for a hip-to-gable loft conversion in Peterlee?
Approvals for a hip-to-gable loft conversion in Peterlee 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.
We check this for your address before design work starts, so there are no surprises later.
