Homes in County Londonderry
Across Northern Ireland you find city terraces, suburban semis and rural bungalows and farmhouses, so the right approach depends on the plot and the planning history.
What is a hip-to-gable loft conversion?
A hip-to-gable loft conversion rebuilds the sloping side (the hip) of a semi-detached or detached house roof as a vertical gable wall, extending the ridge and creating enough space for a staircase and rooms. It is usually combined with a rear dormer.
- Rear dormer and roof coverings to match
- Staircase, insulation, plastering and electrics
- En-suite and fire-protected escape route
What is the guide price for a hip-to-gable loft conversion in County Londonderry?
What hip-to-gable loft conversions typically cost. These are guide ranges; the written quote for your house replaces them.
| Hip-to-gable loft conversions | Guide price incl. VAT |
|---|---|
| Hip-to-gable with rear dormer | £60,000 to £80,000 |
| Double hip-to-gable (detached house) | £70,000 to £95,000 |
What approvals does a hip-to-gable loft conversion need in Northern Ireland?
In Northern Ireland the council handles both planning and building control. Permitted development rules are set by the Planning (General Permitted Development) Order (Northern Ireland) 2015, and there is no party wall act, so we agree access and protection with neighbours in writing.
In Northern Ireland, roof enlargements such as dormers often need planning permission depending on size and position. Building control approval is needed for every loft conversion.
What can change the price or programme?
- Matching old clay tiles can be difficult; reclaimed tiles are often used.
- Scaffolding goes up on the side of the house, which may need a neighbour’s agreement.
