Double storey rear extension
A rear double storey extension can be full height or partial height with the ground floor being extended more than the first floor.
This is usually the case when the neighbours' windows are too close to your house and thus you have to keep away from the 30deg imaginary line that runs from their window for the 1st floor and 34deg for the ground floor.
Of course in some cases these constraints can be removed, but usually are there to stay.
