What You Can Check Before You Buy
Every point below is something we can put in front of you in writing before you pay a deposit. If you are still comparing suppliers, our guide to the truth about expandable homes in NZ covers the questions worth asking every one of us.
Heat-recovery ventilation, fitted as standardEvery expandable home comes with a heat-recovery ventilation unit at no extra cost. Fresh, filtered air is drawn in from outside and heat is recovered from the air leaving your home, which helps reduce condensation and damp.
EPS panels standard, PIR upgrade tested to R-2.72Every home comes with insulated EPS wall panels as standard. If you want more insulation, you can upgrade to PIR panels from $2,300 incl. GST. The PIR panels have been laboratory-tested to R-2.72, so you get a published, tested number rather than the words high performance.
Supplier Declaration of Conformity on the cablingWe hold an SDoC for the cabling and can provide it. Ask and we will send you a copy.

Tiny homes suit some people. However, many buyers run into the same issues: limited floor area long-term, fewer layout options, expensive solar upgrades, and delivery costs that appear late.
With expandable homes, you increase the footprint after delivery. As a result, these expandable homes can deliver 36–72m² without a full site build.

Expandable Cabins — the compact end of the range
If you’re searching for an expandable cabin rather than a full-size home, the 20ft is where most people land. At 36m² expanded, it gives you cabin-scale simplicity with genuine living space — and because it travels compact, it suits tight driveways and sites a full-width transportable can’t reach.
An expandable cabin works well as a sleepout, guest or family accommodation, a home office or studio, farm and staff accommodation, or a short-stay rental. It arrives finished, with a full kitchen and bathroom and double-glazed windows — you choose the layout from 1 to 3 bedrooms.
Want something smaller and simpler again? The 13m² Cabin and the Apple Cabin Pod are fixed-size cabins rather than expandable, and start from $23,500 and $34,000 incl. GST.
Delivery for Expandable Homes (Quoted to Your Site)
Delivery often becomes the hidden cost with expandable homes. For example, some suppliers include freight only to a major hub, then add extra charges for the final leg once they check site access.
Instead, we quote delivery for your expandable home to your actual site upfront with free transit insurance. We price delivery using your region, access, turning space, slope, and crane/hiab needs. Therefore, your fixed quote reflects the real delivered cost. We deliver NZ-wide from our Canterbury base — if you are local, see portable and tiny homes in Christchurch, Rolleston and Canterbury.

Free Customisation for Expandable Homes (So It Fits Your Lifestyle)
Most people choose expandable homes because flexibility matters. In other words, the layout should match your daily life.
You choose the bedroom configuration, kitchen layout and storage, bathroom layout, colours, and finishes. Importantly, we confirm the full specification in writing before you pay the deposit, so you stay in control of your expandable home.
Optional Off-Grid Solar for Expandable Homes (Priced Upfront)
Off-grid power matters for many expandable homes, especially on lifestyle blocks or rural sites. That’s why we publish fixed-price solar bundles instead of vague estimates.
Choose the right solar bundle for your expandable home
3.5kW solar + 10kWh battery
$12,499 incl. GST
For weekend stays or light-to-moderate daily use, the 3.5kW + 10kWh bundle usually fits. It comfortably runs lights, a fridge, device charging, TV, and a water pump, especially on sunny sites with energy-smart habits.
5kW solar + 10kWh battery
$14,999 incl. GST
For full-time living, the 5kW + 10kWh bundle usually suits better because it gives you extra headroom. It handles higher daily loads with fewer compromises and leaves room for future upgrades.
Important note about off-grid power
A home is off-grid capable when the solar and battery system is sized to your appliances, daily usage, site conditions and backup requirements. Off-grid solar runs daily essentials well. However, high-draw electric heating (large heaters, electric ovens, continuous high-power hot water) can overload any off-grid setup. If those loads matter to you, we’ll recommend the right configuration upfront.
