Budget Planner

    Prefabricated Kit Homes and Granny Flats are no doubt one of the most cost effective ways to build your kit home or granny flat.

    Our designs have been engineered for easy assembly allowing owner builders to make further substantial savings.

    Like any building project there are a number of additional items you will need to budget for.

    While the following list is a guide only we have found it to be a close estimate for the majority of times.

    Individual factors relating to the site, its location, demand on builder services in your area all will have a bearing on the final outcome.

Budget Considerations

  • Cost of Kit Home/Granny Flat
  • Delivery costs form your nearest capital city, allow $750/100kms
  • Using a builder to assemble your kit
    home/granny flat, allow 100% of the cost of the kit home/granny flat for the cost of assembly
  • Fixture, fittings and appliances
  • Permits and approvals
  • Access to services
  • Contingency fund, it’s always a good idea to have a small amount set aside to cater for the unexpected
