Renovation priorities
- Choosing between rooflight, dormer or hip-to-gable depending on headroom
- Designing a compliant staircase that works with the floor below
- Steelwork, insulation and fire-safety upgrades
- Adding an ensuite with careful plumbing routes
- Maximising natural light with rooflights
Key considerations
Building Control approval is always required, and head height of around 2.2 metres at the ridge is the practical test for whether a straightforward conversion is viable.
