Also, as Simon mentioned, you are allowed under Class D to add a porch to
the front of a building as long as it is not greater than 3 sq m floor area,
no higher than 3m from ground level and not closer than 2m to any boundary
with a highway.

Is the 3 sq m porch in addition to infilling a recess if they end up being one
continuous area?
