Calculate it yourself

Your sum insured is the cost of rebuilding your home in the event of a total loss. Some things to consider when calculating it include:
  • The square metres of the house
  • Land slope and access
  • Construction materials
  • Quality level of the materials, the finish and fixtures and fittings
  • Number of levels in the house
  • Design style – villa, bungalow, contemporary, one-off architectural
  • Detached garages or carports
  • Special or recreational features like swimming pools, solar panels, outbuildings and retaining walls
  • Demolition costs
  • Council fees
  • Professional fees – architecture, quantity surveyor, engineer
  • Labour costs.

Look at your house plans

You’ll find the square metres there. You can multiply the square metres by a rebuild dollar amount per square metre to give you an estimate of the total rebuild cost. Don’t forget to add in the demolition costs, and professional fees, council fees and costs to remove debris plus any other things that may increase the price to rebuild your house.
