Sebastian Errazuriz, the Chilean-born designer and artist, became famous for his Bilbao shelf, in which a real tree branch was attached to a wall to create an organic display unit. In his latest design, the Metamorphosis shelf, Errazuriz really goes out on a limb. The inspiration for the limited-edition Baltic birch plywood shelf (which is hand-carved by the Italian company Horm) came from his grandmother’s ivy-covered garden. “The dark branches that crawled along the walls were so thick that I would use them as natural shelves for my garden toys,” Errazuriz said. Given the $75,000 price tag, however, your spade and trowel had better be by Fabergé.
