The K21 kitchen model originates from the innovative concept of the designer Norbert Wangen who, in the K series designed for Boffi, has transformed the concept of compact kitchen. The wall or peninsula/island modular base units have no handles: the door opening is guaranteed by the particular wrapping shape of front panels that hides, with close doors, the worktop thickness giving an extremely defined and monolithic appearance to the composition, highlighted by the worktop with basin effect. The front opening is allowed thanks to the upper protruding part (on the worktop) of the front itself. A middle handle-rail in extruded aluminum is set when drawers and heavy-duty drawers are used.
