No, you do not need to know the exact measurements of the building. Some examples of the things you’ll need to know are:

  • The address and age of the building,
  • The construction materials the external walls and roof are made from (for example, brick veneer, double brick, timber, cement tiles), and
  • Property details such as the slope of the land the home is built on and how many bedrooms, bathrooms and garages there are.
