A creation like Boscolo Group’s B4 Hotel in Milan sends us an important signal right now. First of all, it show show the typology of accommodation, in its various forms, is becoming the object of increasing attention and experimentation. The new hotel B4 was created to re-examine, unhinge and completely renew the criteria of th whole class and its promotion and communication strategies. Externally it is distinctive and hieratic, tank to the careful work of the architect Giancarlo marzorati, and internally it is iconic and super functional, tank to the dynamic sign of architect Simone Micheli.
