The design of the three story office building with a great covered and sky-lit courtyard demonstrates that is possible to matched the high profile of company and the super performance of the built environment of the workspaces.

The design concept of the façade has some inspiration  from the works of Peter Struycken, that led to a façade with a continuous rhythm of opaque and transparent parts given a smooth natural light inside and generated different variations of the elevations in each side and each orientation.

The central courtyard is a space for collective use and meeting or small conference and the offices are open trough balconies to this common space. The ground floor hosts the general services and a small show room, the gym or Kenko Dojo, the Ofuro the traditional bathroom, the Hoseido a tradition Japanese thé room and the salle the Diner with the kitchen with natural products.

The technology of the building is an hybrid mechanical and natural system with active slab and natural ventilation; Wood finishes, open glass walls and green tatami-like carpeting join Japanese serenity with an Italian architectural sensibility.  The bio climatic approach is based on a hybrid system, with mechanical and natural ventilation and active slabs, with many internal and external acoustic dampers to keep the quality of environment very high for indoor air quality and acoustic levels.

The building design is strongly referred to the highest level of building sustainability targets in terms of natural light, energy consumption, carbon footprint and internal comfort.

The construction technology of the façade is a layering of precast wooden panels, high insulation and ventilated Grc slabs. A high level product finds its corporate home in a design that accords good health to its corporate culture as well as its ultimate customer.
