Expandable Homes

Express Portables Class 1a Expander Homes are fully self-contained, certifiable dwellings built to comply with the National Construction Code (NCC) and Australian Building Code (BCA), designed for permanent residential use.

Yes, the Class 1a Expander Homes meet NCC and BCA standards and come with the necessary certifications for structural, insulation, plumbing, and electrical compliance.

Installation must be carried out by a licensed builder or someone holding an approved owner-builder permit to ensure compliance and safety.

No. Our Expander Homes are not certified for sites that require a Bushfire Attack Level (BAL) rating. If your property is located in a bushfire-prone area, additional assessment and modifications would be required, which are not currently offered by Express Portables.

We provide the Class 1a Expander Home (packed down), building certifications, site-specific footing designs, delivery (if quoted), a detailed installation guide, and structural warranties.

Costs like development approvals, site preparations, crane hire, appliances, furniture, decks, patios, gutters, and onsite installation services and insurances are not included.

Factory construction typically takes 9-11 weeks, followed by 4-5 weeks for international shipping to Australia.

These buildings are not acoustically reated and have not undergone sound performance testing or engineering.

You need to organise soil testing, footings, site works, and connection to utilities, usually via your site builder or other local contractors.

You will require development approvals and certification from a building certifier before installation, including a final occupancy certificate.

Our homes use 60mm polyurethane panels offering high thermal insulation and energy efficiency, superior to typical polystyrene panels.

Structural defects are covered for 6 years and 6 months, while non-structural defects have a 6-month warranty.

Yes, we offer options like decks, patios, air conditioners, and hot water units, which can be added separately to your Quote.

Yes, all windows and doors feature aluminium frames with double glazing to improve thermal and acoustic performance.

Your licensed builder will unload the home onto the engineered footings, install and assemble the Expander unit, connect all necessary services (power, water, sewer), complete structural fit-offs and coordinate required inspections to obtain final certification.

Yes, we arrange delivery across Australia and can coordinate transport as part of your package.

Start by contacting our sales team for an initial consultation or visit our Gold Coast Display Village. We will guide you through site suitability, approvals, contracts and the process.

No. The buildings do not have a snow load rating.
