One single module “regal” takes form with coming of these modules together and it creates a whole bookcase system. The order of system takes form absolutely due to the user’s creativity and the easiness of usage. When the bookcase occurs, the continuity of linear route draws the attention. Regal offers to user the chance of adding new module due to needs by the time or it can be used in one single module too. The material that is used is perforated metal sheet and the most important contribution of this material is the easiness of immobilizing. With taking the advantage of the holes on the material, module can be immobilized in intended way with the help of an edge-binding element. It can be bound in an upside-down or perpendicular position. Regal won 3rd prize at IV. National Household Furniture Design Contest in 2010.
