2. Maximum Floor Space (After Construction):

  • 330 if the lot has an area of at least 450 square metres but less than 600 square metres,
  • 380 m2, if the lot has an area of at least 600 square metres but less than 900 square metres,
  • 430 square metres, if the lot has an area of at least 900 square metres.

3. Rear Setback:

(b) an inter-allotment drainage system (a Registered Drainage Easement), or

(c) an on-site disposal system ( we must construct a ‘Rubble Pit’ in the rear yard).
