A new architectural trend has appeared, mobile homes which can be transported, some are built on wheels, turning into rolling houses in the most literal sense of the word. Others can be easily carried on a truck and be moved to the places their owners desire. Tiny houses, of less than 20 m2, where the main space is at the same time kitchen and living room, which tend to have a small loft for the bedroom and where there is no place for things which don´t have an essential use, giving their owner the necessary comfort.
