Nothing captures our collective imagination quite like a majestic treehouse. Tashen’s new book Tree Houses: Fairy Tale Castles in the Air features stunning images of 50 of the world’s most amazing tree house designs. Structures range from traditional A-frame homes in miniature, to bulbous, futuristic dwellings that cling to behemoth branches. There is a true wealth of images to be savored in the glossy photos captured of each arboreal abode in Taschen’s 352 page book.
