This may seem to defeat the idea for some being “green” but here in the Philippines its not always about recycling simply because containers aren’t readily available.
Take a shipping containers basic structure and what I see is a very simple building block that can be replicated side by side. and more importantly easy to build. Now what your doing with the container blocks will make a difference in the support structure and density of the steel for load bearing purposes. Why I am pointing that out is that someone may go “its cheaper to buy a container” well here in the Philippines its not unless you know something I don’t.
Your main dimensions you need to work on are based on transportation needs and not the home itself. For example if you took this open sketched version as a real building block you can actually attach other containers in any direction. Even stacking one on top and removing several of the floor beams for a staircase.
Why this is important is that from an engineers point of view it becomes extremely easy to put a value on materials as well as labour costs. You can decide on sections do you weld or bolt? but all in all you can get a real accurate price structure on your modular container construction.
Building them within standard transportation design metrics also means that you can make these off site or more importantly speed up production and lower costs. These buildings can be built in a factory and shuttered along on a conveyor system or as we used to do in the UK moved by forklifts. E.g. outside we used to weld the frames together before they were transported indoors to have the walls installed.
Pretty much the whole thing can be produced on site in a factory then all the modules can be joined together at their final destination. But that’s not always useful and with many of the areas in the Philippines its full of mountains. How many containers can you fit inside one if just cut and stripped down ready for putting together and welding/bolting? 2 – 3 trucks could be transporting virtually the entire house in parts that could physically be carried and erected on site.
This idea is something I have thought of due to one of my wife’s relatives having half a mountain for sale and this could see homes perched on the top and the most sensible way of transporting materials to the location.
