I'm planning a second storey extension on top of an existing ground floor extension. Ideally this bedroom would be accessed by a second set of stairs at the back of the house. So if you went up the main stairs you wouldn't be able to get into the new bedroom - the only access would be via the new stairs at the back of the house which would go directly into the room.
Is there a maximum angle for internal stairs? There's not much room at the back and the stairs may have to be quite steep.
Obviously this will all come out in the planning permission and building regs but I wondered if anyone knew the answer?
