This great idea would be perfect here in Fiji! Solar panel, composting toilet, and folds down to handle extreme weather.
So many un-used shipping containers here. Mountains of them sitting around in “container parks” for sale. Each one costs about $5000 FJD (about $2500 USD) yet the habit here is to build corrugated iron homes for more than ten times the cost which are not cyclone resistant, let alone flood tolerant.
If these homes were also on wheels, they could be moved to higher ground in the event of cyclones and floods, often caused by tidal surges, or even the rising water of the ocean due to climate change which is as we speak, causing villages to relocate to higher ground.
