Here is an excellent example of minimalist housing design. A bicycle pulled miniature vardo that can collapse into a low-profile trailer for the road if needed.
It’s an admirable design that appears to have gone through a couple design changes from two wheeled to four wheeled. It could be a very inexpensive shelter that is dry and off the ground. Clearly this guy is a fan of human power and innovative design.
He also has a build page for his impressive Velomobile here.
