American Levi Kelly has built the smallest microhouse ever - with an area of only 1.8 m². It can be transported as a trailer, even in a car. The tiny dwelling has the bare minimum: a sofa, a bed, a kitchenette and a toilet. There is also a remote shower and electricity is generated by solar panels on the roof. He says he spent 5,000 dollars on the project and now hopes to get into the Guinness Book of Records
