This tiny, experimental house was built in Scandinavia using glulam techniques and lots and lots of wood. But not as much wood as a larger house would. The architect, Torsten Ottesjö, built at this scale for many reasons (including the economy of such a scale) but also because of how it feels to inhabit a space this size. By curving the surfaces of this small abode, the architecture here is actually becoming something like a piece of furniture. According to the architect:
I wanted to work with all surfaces of the room and create a room which in itself was comfortable. I wanted to create surfaces where you can sit and stand, lean against and lay on, giving you the ability to lean comfortably against the walls as if they were the back of an armchair. By optimizing the whole room, you liberate a lot of volume which in its turn makes a small room spacious. In my mind, a well-designed room does not need to be big or filled with furniture.
You can even watch a video taken from something flying around the house.
