Daylighting Standards for Rooms
Daylighting effects on all rooms except halls, landings, bathrooms and utility rooms will be considered. Planning permission is likely to be refused if an extension would unreasonably reduce light entering windows of other rooms.
In terms of daylighting, the effect on all rooms, apart from halls, landings, bathrooms and utility rooms will be considered. Where an extension would be likely to reduce the amount of light entering the window of a room, other than those indicated above, to an unreasonable degree, planning permission is likely to be refused.
