A loft conversion turns dead volume into a bedroom and bathroom, and its feasibility comes down to numbers: available head height, stair position and the permitted development volume allowance of 40 cubic metres for terraces and 50 for other houses.
- Head height and stair feasibility check
- Dormer, hip-to-gable or mansard design
- PD confirmation or planning application
- Structural design and building regulations package
Does a loft conversion need planning permission? +
Frequently not: rear dormers within the volume limits fall under permitted development. Front dormers, mansards and conservation-area lofts usually need an application. We check your property's planning history, conservation status and permitted development position as part of the free consultation.
What head height do I need? +
Around 2.2 metres at the ridge is the practical threshold for a comfortable conversion. We measure and confirm this at the first visit.
