The Nazaku Bookcase is the most versatile modular shelving system we have ever created. Designed by Doug Green, it is assembled without any tools or fasteners. Martin Simpson, who also crafted the first prototypes, performs the assembly with Doug assisting. In addition to a limitless variety of configurations in the height and length of the assembled components, we’ve added color as a new dimension in the design. Individual components (backs, sides, tops, shelves and inserts) can be custom tinted to produce a geometric color composition to suit artistic imagination.
