Some people take the proverbial "size doesn't matter" too litteral, I believe. For instance, Helenita from Madre de Deus (Brasil) lives in this ridiculously narrow house. It is about one metre wide, and ten metres high - giving it quite a remarkable physical appearance.
I'm not too sure about the truth of all this (for instance, the interior of her kitchen below looks quite a bit wider than one metre - or she must be a very tiny midget), but the idea of the building is interesting, and the image is more than stunning.
