Do I need approval to build a porch?


A porch is exempt if:

  • the floor area does not exceed 30m²,
  • a door of external quality is retained between the porch and the rest of the house
  • Glazing below 800mm in windows and 1.5m in doors and sidelights should be safety glazing.
  • You are also advised to ensure that a porch does not cover outlets to boilers or other flues as well as the only ventilation openings to WC's and other rooms.
