One of the main issues that are cropping up with shipping container architecture is things are often pushed onto recycling being the green solution, then you get greens telling us how toxic the paints are and how transportation is a waste of energy.
The important thing is though if its available and usable its green. If it isn’t and in many cases they aren’t then we are looking at modular construction for buildings which is a more viable method for many uses. I originally worked on this type of system in the late 90s for use in classrooms and clinic construction in the UK as a temporary solution.
Temporary often means a decade as they are generally put into place as an immediate solution while discussions, planning and funding are found for building the main buildings that will replace them. During this time though many of these units would return after years of being in the field and be revamped before sending back out. Which does show the fact they were extremely reliable and resilient to weather. Add to that having slot walling meant that upon return walls would be rejigged to suit the new layout for the building they were becoming. Very little wastage as all windows and doors ended up back in other buildings if not used.
The fact is the shipping container idea developed this new concept which is now fairly old in use but still has a growing market which does appear China is gearing towards the housing industry with.
I can see this being the future of shipping container homes as the dimensions are still in place although the walling systems have been completely redesigned.
