The idea for this building came from one single part - a Paled Fence, seen in the Newest Items of a local store on bricklink. It seemed to me that the fence would be an excellent decor for a window part (under window). Drew a couple of variants, and then completely turned it upside down :) Enchanted diamond by Maxim Baybakov, on Flickr Enchanted diamond 1 by Maxim Baybakov, on Flickr Enchanted diamond 2 by Maxim Baybakov, on Flickr Enchanted diamond 3 by Maxim Baybakov, on Flickr
According to calculations, the roof was supposed to occupy a width of 14.14 studs.
But due to the fact that each tile 2x2 is quite a bit less than 2 studs and roof is assembled in this way, it fits into 14.
