​Here are a few of the features that will be demonstrated in this working prototype of a self-powered tiny house on wheels that is affordable, eco, mobile, modular, versatile, as well as off-road and off-the-grid, essentially a self-contained living biome.

This tiny house may be parked anywhere without the need for a hookup. You may even stop in a national park in, say, a dried-up dusty river bed in the desert with all the mod-cons and functionality of a normal suburban house + a whole lot more.


  • Double-size bed folds up into a generous day lounge sofa.

  • Air to water generator generates over 15 litres of water per day (upgradable to 30 litres)
    May also be used as an internal clothes drier & dehumidifier, with anti-mould capability.

  • The removable trailer may be used as the deck, or to move other modules.

  • Full hi-speed internet WiFi using Elon Musk’s Starlink Internet dish offering up to 330/500 mbps pending coverage.

  • Efficient instantaneous electric hot water heating system.

  • Fully self-contained shower cubicle.

  • Washing Machine (full size, 8.5kg)

  • Clothes Drier

  • Composting toilet / Porta Pottie.

  • Kitchenette with Kitchen Sink, under sink storage and cutlery drawer and storage cupboards.

  • Microwave combi convection oven

  • Induction cooking hotplates.

  • Climatically efficient build with a Mitsubishi full reverse cycle air conditioner for heating & cooling.

  • Full Smart home assistant speaker featuring full voice control.

  • Smart full colour lighting control (even turns into a disco).

  • Storage tanks for grey and fresh water in the sub-floor.

  • Roof guttering diversion into a first pour tank and finally stored in sub-floor tanks.

  • Indoor planter boxes for growing micro-greens and herbs.

  • Interconnectable with other similarly designed modules to build a pavilion or exploding house as big as a mansion if desired via 2-3 connecting doorways.

  • Signature large round portal window.

  • Built to NCC (National Construction Code).

  • Fully legal & built for certification.

  • Legally removable from the trailer and placed on the ground with tie-downs and stumps or on a slab.

  • Metal base and sub-floor.

  • Connectable to an electric vehicle (BYD) that may be used as a house battery.

  • Additional solar trailer recommended.


We feel that our tiny houses on wheels combined with smart home technology, innovation, and continued R&D may lead to improved living outcomes for people.


We see outcomes in terms of affordable housing, environmental sustainability, scalable cohousing & communities, off-grid living, as well as reducing the impact on the planet by enabling more efficient infill housing and land sharing, enabling mobile and nomadic living.

This should ultimately restore a sense of connection and community for people and help lead to a more meaningful way of life.

We plan to open-source the design, and are always looking for builders and manufacturers to help make these affordable tiny houses for an exponentially growing mainstream tiny housing market.

  • < 4 m at its highest point (when on trailer)

  • Trailer rated 3.5 tonnes (GTM)

  • Estimated weight < 3 tonnes.

  • Curved pitch roof

  • Internal 10 cm wall structure made from a quality CNC cut plywood

  • Polyester insulation batts

  • Shadowclad exterior

  • Pine ply interior & finish

  • Strong carbon-negative structure.
