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 Bathgate?
In Bathgate, 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 Scotland sit near the national average for this kind of work, and the range for Bathgate reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a hip-to-gable loft conversion in Bathgate?
Whether you need planning permission depends on your house and its location 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

Typically 7 to 10 weeks on site. Design and approvals beforehand usually take 6 to 12 weeks.
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.

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.
Will I need building regulations approval?
Yes. All loft conversions to habitable rooms need building control approval for structure, fire safety, insulation and stairs.
