This smart eight feet tall bookcase by the canadian designer Karen King features a built-in ladder that pulls out to reveal three steps. Closed, the ladder rungs align seamlessly with the lower three shelves. You can use it for storage, climbing and keeping watch. All pieces have been designed and built in Canada using reclaimed lumber or sustainably harvested hardwood. It´s build mindfully to last generations. Additionally it makes it pretty easy for small people like me to reach the top of the shelf.
