I was watching ‘Real Orange’ a couple of days ago and there was a short piece on housing being constucted from surplus shipping containers from China!
Apparently, there are so many surplus that new laws have been passed to stop shipping companies from stacking them in near residential zones, because they’re piled so high that they can block out sunlight.
Surprisingly shipping containers make pretty good pre-fab units: they’re insulated, already have hardwood flooring, are termite-proof and have decent internal proportions.
There was an architect in the piece, who specialised in modifying them to make low-cost apartments and also houses of multiple containers.
