TU23 is Rossana’s tall-unit system, not strictly tied to any single model of kitchen, but adaptable for use with any of the variety of products in the range. With hinged, sliding, coplanar or retracting door panels, the system gives rise to an infinite number of potential layouts and material and chromatic pairings between external and internal parts. TU23 Architectural is the system of components that matches and is integrable with the TU23 tall-unit system. It was developed to advance the latter’s functionality. It consists of extra-deep cabinets, positioned directly on the ground with no obstacles, which form built-in compartments and small walk-in spaces, completely concealed behind the front of the units and achievable without carrying out interventions on the wall. The door panels, whether those with hinges or the sliding fold-away doors which can be completely hidden, fit together perfectly flush and can be matched with wooden panelling at the sides or the top. Support structures for the external kitchen, internal storage units, laundry rooms, pantries, utility rooms, service areas and wine storage are the main examples of what the compartments offered by this system can hold. TU23 and TU23 Architectural, designed for mutual interplay, take into consideration the real ways in which the kitchen environment interacts with the architecture, and by adding their various components to the building design, they can give rise to new functions. A realistic approach, testament to Rossana’s overwhelming impulse towards innovation.
