Additional costs for
The Purchaser to Consider

While Express Portables supplies the Expander Home, there are additional third-party costs to consider.
The following is a guideline only and can vary based on location, site conditions and local council requirements.

Geotechnical Engineer
A soil test assesses soil conditions to ensure your footing design is appropriate and compliant.
Building Certifier
A licensed certifier is required to approve your Class 1a dwelling before installation and issue a final occupancy certificate once complete.
  • Review plans and engineering documents
  • Lodge approvals with council
  • Coordinate required inspections
  • Issue the final Certificate of Occupancy
Council Fees & Government Charges
Council related fees are not included in your base package and should be factored into your budget separately. These costs are site-specific and determined by your local council or state authority, depending on the zoning, intended use of the building, and any applicable overlays or planning schemes.
Transport and Crane Hire
Transport and crane services are a critical part of delivering and installing your Expander Home safely and efficiently. These services are typically quoted separately or itemised by Express Portables.
Site Plan
Customer to provide their own site plan with orientation and setbacks. We recommend a service like siteplansonline.com.au or engaging a site surveyor.
Foundations
The Expander Home is delivered ready for installation; however, foundations and footings are installed by the site builder/concreter. The purchaser will need to engage an engineer to conduct soil testing and design site specific foundations. Express Portables work with a network of engineers familiar with our expanders for sign off.
Installation
The installation of your Expander Home must be carried out by a licensed builder or an individual holding a valid owner-builder permit, in accordance with local building regulations. Installation involves:
  • Positioning the home on engineered foundations or footings
  • Connecting services such as power, water, sewer/septic, and stormwater
  • Completing structural fix-offs, including expansion and sealing
  • Carrying out any on-site works like decks, stairs, or ramps if required
  • Coordinating inspections as part of the final certification process

This ensures the dwelling is installed safely, in full compliance with Class 1a requirements under the National Construction Code (NCC) and qualifies for final occupancy approval.

What Our Customers Say

D

Transparent pricing, no hidden surprises, and a guided process that actually made sense. The finance option through Handypay made it accessible for us. We moved in within 5 months of our first enquiry.

— Daniel Okonkwo

B

Got council approval in our regional area which I was told would be tricky. The documentation package they provided made the certifier's job easy. Our home is now fully compliant and we're living in it — amazing.

— Brett Carmichael

D

From the first call to delivery day, the whole team was incredibly professional. They answered every question we had about council approval and made the entire process stress-free. Couldn't be happier with our new home.

— Debra LeCourt

S

We looked at several portable home companies and Express Portables stood out immediately. Proper NCC compliance, Australian engineering, and a team that actually picks up the phone. Worth every cent.

— Sarah Nguyen

J

The 40ft Multi-Expander is genuinely spacious. We use it as a full-time residence on our rural block in Queensland. The 7-star insulation rating means our power bills are surprisingly low even through summer.

— Joanne Whitfield

M

My wife and I had a genuinely great experience. We were nervous going into it but the site assessment gave us so much clarity. We knew exactly what was needed before spending a dollar. Highly recommend starting there.

— Mark Headland

Frequently Asked Questions

What is a Class 1a Expander Home and how is it different from other Expanders?

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.

Is the Expander Home compliant with Australian building regulations?

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

Who can install the Expander Home?

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

Is the Expander Home suitable for bushfire-prone areas requiring a BAL rating?

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.

What does Express Portables include with the purchase?

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.

What is not included in the Expander Home package?

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

How long does the factory construction and delivery process take?

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

Are the Class 1a buildings acoustically rated??

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

What site preparations do I need to arrange?

What additional approvals or permits do I need?

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

How does the Expander Home handle insulation and energy efficiency?

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

What warranty coverage do the homes have?

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

Can I customise finishes or add extras to my Expander Home?

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

Are the windows and doors double glazed?

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

What should I expect during the installation process?

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.

Is nationwide delivery available?

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

How do I get started with purchasing an Expander Home?
