Notwithstanding our complaint about the title, there are some interesting projects here- the CorePod takes a ranch-house type plan and stacks it in a superstructure. As your needs change or you are relocated, just unplug and take it with you. The LaCan project “has been designed with contemporary Americans in mind. Not only is it built to move - instead from moving to a new house with each lifestyle change, you just take it with you - "it can expand to accommodate growing families, or contract for empty nesters."
We like the MiniMax house, which expands like an accordion to apportion space to different areas as they are needed.
