The K21 model is the result of Norbert Wangen’s innovative approach to the compact kitchen. This model stands out for its system of base units that can be configured in various layouts—wall-mounted, peninsula, or island—offering versatile solutions for any space. The defining feature of the K21 lies in its handle-free doors, with an upper edge that sits slightly higher than the kitchen worktop. This detail not only serves as a practical grip but also creates an enveloping, seamless surface that visually conceals the profile of the countertop, giving the composition a monolithic appearance.
