Weehouse Miniature Prefab Module

One of the greatest strengths of tiny prefab homes or additions is their transportability – and this design is no exception. It is elegantly constructed from steel and wood and its use of Ikea furniture and simple finishes makes it an affordable $125 per square foot of space. These can be added as-is to properties or rooftops or can be easily added to with porches, staircases and additional modules as well. (Source)
