Walthamstow: rooflight loft conversion under PD

The brief
Add light and a study space with minimal external change.
PD question answered
Are rooflights permitted development?
Yes, if they do not project beyond the existing roof plane and respect height limits.
Constraints
- No projection beyond roof plane
- Maintain existing roof appearance
- Internal layout constraints
What we did
- Used low-profile rooflights
- Planned the layout to maximise daylight
- Documented compliance for clarity
Outcome
Extra space with a subtle exterior and a clean PD route.
