The all-new $1500 mother-in-law suite
The company manufactured the prototype in the United States but has plans to move manufacturing to South Africa soon.
Given the huge homeless problem facing the United States, these could also come in handy here. They're lightweight, easy to assemble, and easy to dissemble and move. At $1500 a pop, the cost is minimal and definitely worth a try.
Of course they're also perfect for a cranky mother in law. Set one up in the backyard and add a barbecue and hose for fully-independent living.
