The "Savo" building, located in the Split city center core, was turned into a shopping mall at the beginning of this century and, by a guerrilla action in 2010, was transformed into a hostel in 100 days. Public communications - escalators, panoramic elevator and the staircase were kept, and shopping spaces were partitioned by a system of walls that contain everything necessary - beds, lavatories, showers and toilets. An urban metropolitan character as well as a continuance of the public realm within a historical membrane were performed.
