The Nu Hotel in Milan, made in an existing building in Via Feltre, preserves only the outside walls of the existing building. All 5 floors of the building were completely emptied out, including the patio, and architects Simone Nisi Magnoni and Sabrina Gallini designed a hotel with 38 rooms, a meeting hall, a lounge bar and a Nu Italian Restaurant.
The interior design is based on contrasts. The architects avoided the standardisation so common in hotels and designed every single element to be unique.
