When Mogens Koch drew the first lines of his bookcase system in 1928, he created a shape which has been copied again and again all over the world. The system with its square bookcase units offers almost endless flexibility with countless elements. Characteristic of both the design and the craftsmanship are the beautiful dovetail and rabbet joints, which create strength and stability in each module.

This bookcase is square and reversible measuring 76 cm x 76 cm x 27,7 cm (D), with six sections in total. When turned in position with low sections it is ideal for books of smaller formats. Turning the bookcase, it is ideal for books of larger formats. The bookcase can be mounted on the wall or placed on a leveled plinth I. Designed by Mogens Koch in 1928.
