I have been reading about mini or micro homes. I have seen some very small - under 150 sq feet, I'm not looking at that small, I'm thinking maybe about 500 - 700 sq ft. Has anyone ever lived in one or seen one aside from on the internet? I've watched some Youtube videos and seen cute style. I am also interested in the plumbing and stove and fridge. Are they special types for small houses or normal size?
