      Planning Process

        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.
      • If using a builder to assemble your kit home then roughly allow the same cost of the kit home for the cost of assembly.
      • Fixtures, fittings and appliances.
      • Permits and approvals.
      • Connection to services.
      • It’s also a good idea to have a small contingency fund set aside to cater for the unexpected.

      Exclusions - All Finish Materials

        The following finish materials are not included with the lock up kit.

        Floor Coverings
        Internal Door and Jambs
        Skirting and Architraves
        Gyprock and Cornices
        Paint and Tiles

      Exclusions - Electrical & Plumbing Materials

        If you are assembling your Kit Home as an owner builder you will need to engage a licensed electrician and plumber and they will typically provide these materials.

        If you are engaging a builder to assemble your Kit Home they will include these items in their quote.
