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 Renfrew?
In Renfrew, 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).

Do you need planning permission for a hip-to-gable loft conversion in Renfrew?
Before anything is built in Renfrew, we confirm which approvals apply in Scotland. In Scotland changing a hipped roof to a gable often needs planning permission, because dormer and roof enlargement rights only apply well away from boundaries. A building warrant is needed before work starts.
Scotland has no Party Wall Act. Work on shared walls is governed by your title deeds, the Tenements (Scotland) Act 2004 for flats, and common law, so we agree arrangements with neighbours in writing before work starts.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
