Prefab, minimalist housing by the MUJI brand. The Muji Hut of Wood by designer Naoto Fukasawa. This one comes with a Japanese style bath, a wood-burning stove, and a wall of windows. Love! I wish I could have this as my "she" shed/personal office off of the house, especially if the windows faced trees/nature. It could function as a part-time guest (mini) house.
