Billboards are a blight. But they generate a serious amount of money for the owners of the land they sit on. The Gregory Project, by Slovakian firm DesignDevelop, has created a tiny triangular house on stilts that could be used as housing for the homeless. They tell designboom:
The proposal increases the functionality of the structures in a way that the insides could be turned into living spaces. Such an object would produce minimal maintenance costs, which could be paid through the rental space of its façade.
The units are actually quite lovely inside, with a loft bed you reach by alternating tread stairs, a tight bathroom and decent kitchen. While the location next to a highway isn't exactly prime, all the windows face away, and the advertising would generate enough revenue to subsidize the whole thing.
A drawback is that highways are not usually near the kind of services that the homeless need. However the single most important need is affordable housing. This isn't such a silly idea.
