When George Bernard Shaw began designing his ideal writing hut, he decided to construct it on top of a rotating Lazy Susan. It was drawn as a simple 8'x8' square with two large windows on one side for lighting and heat. With ascetic efficiency, the building's windows could be turned towards the sun during the winter--allowing solar energy to warm up the room--and turned away for the summer. I would've guessed that the hut was built within moderate climate if it wasn't for the fact that "it has a sloping roof to shed rain and snow build up."
Not only was he a literary visionary, but a clever engineer. (One might even say that he Shaw solutions...)
