Owning personal logistics is a luxury dream for citizens.
Nowadays in capitalist cities, only the state capital and giant companies have access to logistic systems.
Therefore, the price of goods are higher than the cost of using the logistics system.
But I found a hint far in South America, where local people put the 20ft container on a small wooden boat and transport it by themselves.
Rather than consider it as unmodernized. It is more rational there.
If you try to attempt this personal logistic in Tokyo, maybe we can change the city if we consider redesigning how we build a home.
We can load timber purchased individually at a lumber shop at Shin-Kiba in a 20ft container,
and make a house where we can go back up to the Sumida River with a wooden boat.
Containers can be used not only as a package for transporting goods but also as the foundation of a house which also serves as a living space.
The traditional Japanese wooden home dimensions, which are based on tatami mats are adjusted and adapted to be loaded on the existing logistical system.
On the contrary, the building materials that constitute the Sumida River House are determined by three aspects.
First, the volume of a 20ft container. Second, the loadable weight of a small boat that can trace up from the river mouth to the Iwasu floodgate.
And third, the shallowness of water.
Several owners charter a small boat for a short period of time and load timber purchased in Shin-Kiba for the original price.
Additionally, with the help of a local builder, you will be able to get a cheap, non-mass-produced house even when you are not a superhuman self-builder.
