Shipping containers are an exciting idea but not the solution to the problems.
Major problems with shipping containers home:
1) Shipping containers are not material efficient. If you took the same amount of steel by melting down a container, you could get a lot more housing. Probably 2x or 3x as much. So the containers are not material efficient and not anywhere near as cheap as they could be.
2) Containers in pictures look really cool when they are stacked in all sorts of strange ways like legos, but think about how dangerous it is. Having your house hang half-way outside or offset can ruin the structural integrity of it.
3) Micro homes is really cool, but once you put in all the sanitation, and systems for electricity, heat, AC, pipes, airflow, fire safety, the container becomes smaller and less liveable. It also becomes a lot more expensive.
Some people have this idea that you can just take a container, drill some holes in it, and then that is it.
How are you gonna drill for a toilet and a shower? how is the piping going to work once you stack that container on top of others? How are you going to get electricity?
Never the less I am exciting about the idea of moveable modular home. I think container home has the right idea. Think about that container is the most easily transportable thing with the amount of cranes, trucks and ships who transport these containers all over the world. It's the perfect standard for transporting all over the world.
Containers can easily be sent in after humanitarian crisis or disasters. Containers can be taken up and shipped away. Containers have few of the problems that many other materials have.
What we need is a new modular system with a prefix for electricity/heat/sanitation/water/exits/airflow. If we build a new system of modularity, we can make a system where you can actually easily stack the containers on top of each other in a much more cost effective way, and a much more safe way.
It needs to be designed cleverly with the idea that you can just slide it in and hook it up, and you're good to go.
At the same time you'd also need a form of modularity, so two units can be fit together. Imagine if you lived alone, met someone, and you could combine your units into one larger. that you could transport your unit with you when you moved across the country. If the unit fits on a truck, a freight train, or a boat and can be lifted with cranes, you're able to create a enviornment where you can more easily transform neighborhoods.
Clever design as far as furniture would be something like easily accesable hidden walls, beds hidden folding out from the wall. built in closets.
materials that these should be build from should flexible and removeable, so each of the 6 frames could added or removed. I imagine you'd have a container dimension sized base living quarter unit, and then a square unit with the same depth most people would add on the end of the unit as a bathroom.
So prefixed additions, build in standard measurements for windows, airflow doors, would make it truly modular and not waste materials.
Finally, the materials themselves should reflect the place its being build. In Qatar you'd need something that pulls heat away from the main compartment (like Aluminium, but obviously that would not be a cost effective material), and in Russia, you'd need something that keeps the heat inside.
But I think one of the solutions to all of this might be solar panels. I imagine something like you would have a base frame with solar panels, and then fit containers inside. So imagine a sort of container holder. that is hooked up to the local electricity grid and water and sewage facility. You then just slide in containers, and on the backside you have pre built steelstairs, that allows people on higher floors to get down.
Containers are really cool, but they are like a alpha prototype. Now we need to get into beta and try some different ways of taking a modular design, but reducing cost, material while increasing safety.
It will require really smart engineering a new standard. How do you pay for your electricity? how do you determine how many units you can have in a space before it becomes unsafe? do you risk fire hazards with a open modular system? How do you make sure there is enough electricity for everyone? is there any unforseen problems with just hooking / unhooking mobile units on and off with regards to sewage, water, electricity and heat?
how would you combine several units? would every unit facility need a crane? could you have a mega park with 1000 units? how does someone on the bottom get electricity from solar if the higher units are blocking it? would you need special infrastructure and tech to slide a container in and out? what are the limits of combining several units? how do you make sprinkler and piping with the walls? would you have pipes in the studs or in the floors or ceilings? is there a steel beam that holds it together? what are the problems if someone wants to have a tall narrow two story building, or make a L shaped home? could you make a fat stack and place 3 buildings next to one another?
what materials could you build out of in the most cost effective way? how do you make a modular system that will be future or foolproof 30-50 years from now? do you make different standards based on different countries? how much customization inside does a owner have to make or build inside? does the owner have any choice of how and where the kitchen or the bathroom is? how much cheaper is it all going to be compared to be building a wooden house?
But the idea of the modular home is truly amazing. what could make it even more so, is imagining if you could have other modular parts you could add, like a square garden or front porch.
The problem as I see it, is that the more you think about it, the more you get away from the naive (but really cute) idea that you can just dumb a container in the middle of jungle and then everything is perfect. It just isn't that simple.
