Found this great little house/shelter thing that is designed to be a non permanent shelter. So basically a glorified tent. here is what the archatech said:
buBbLe tries to advocate a space and a time for non-permanent dwellings. We believe it is possible to create contemporary residential units that penetrate the city’s interstitial spaces. These units would thus complete the city’s functioning and allow for the newly arrived, or displaced people in general, to gradually settle in the city. Semi-regulated spaces that, accepting the transience of new residents, alter their character slightly and contribute to social inclusion.
