Micro-house by Chinese design studio Liu Lubin is a structure based on the minimum space people would need for a living. It is by no means extravagant, but the house would allow basic human movement like walking, standing, sitting and lying; arguably in very cramped quarters though.
It has been designed to work both as a standalone structure, or in a colony where many such houses could easily stack up to create a residential cluster. Seeing that the structure is expected to move, Micro-house is built out of light and strong glass fiber reinforced plastic. The designers say each particular house could actually be assembled by hand.
