Recently inspected this house. 52 Gulfview Drive One Tree Hill SA 5114 - House for Sale #123367778 - realestate.com.au It seemed a lot smaller than 213sqm of living as suggested from floor plan pics. I added up all rooms allowed for bathrooms and hallways and could I only get to living of 170sqm approx I called the agent who called her "floor plan" guy and he said that they are correct and that he is including the external walls as living? Is this normal? I though living was where you could physically "live" in not walls I may be wrong could someone enlighten me on this?
