I think it will be hard to better in terms of gray energy to build a house.
Only downside: it is a single-person house
(or 2 must be permanently glued)

Roll it is a cool experimental house, resulting from the collaboration among different institutes within the University of Karlsruhe.
You gotta roll the mini house to separate between different sections-a bed with a table, an exercise cylinder, and a kitchen with a sink. And the modular protype takes the very name of that act only.
The structure consists of an outer shell that is composed of four outer rings, a torsion inner shell membrane and a covering.
When required, the array and character are restored into an inhabitant type. Additionally, the foreground of this empirical housing is provided for a bathroom, sink, and a range. A hardware container is more easily available than the collapse that provides liquid for all workaday wants of the residents. The empirical housing is not intended to supply all of its residents; nonetheless it's an expanse, wherever you'll get to the tone of the bimestrial run and reason the noesis of frail mastermind.
