Define the home and site requirements
List the location, access, land conditions, intended layout, household needs, services and any site restrictions. Ask a qualified local building professional to assess the site and explain which reports or approvals may be required.
Read the exact manufacturer and builder documents
Request the system drawings, materials, transport plan, assembly scope, warranty, inclusions, exclusions, installation conditions and completion records. Confirm which parts are factory-built and which work occurs on site; do not infer performance from a general prefab label.
Compare total project quotes
Obtain current itemised proposals covering design, permits, site preparation, foundations, transport, crane/access, connections, finishing, inspections, taxes and variations. Compare like-for-like scope and ask who bears delay, damage and coordination responsibilities.
Verify credentials and approvals
Check the builder’s licence, insurance, registration and local approval pathway with the relevant state or territory authority. Use qualified trades for electrical, plumbing, structural and other regulated work. Seek independent legal and financial advice before signing a major contract.
Separate home construction from cleaning
Building, certification, repairs and commissioning are not cleaning services. A post-construction clean can only be scoped after the site is handed over and the builder confirms which surfaces are ready.
