Inside the Block 20, complex commercial uses are prevailing: trade, business and hotel structures, and underground floors will be parking space. On the subterrain floor there are a hypermarket with storage space and a part of the hotel structure. On the second and the third underground floor there is the depot of the City Library. On the floors above the ground there is the hotel structure and shopping center with additional functions (cafes, restaurants, dancing club, cineplex, etc.)
The entrances to the complex are positioned from all sides of the facility and in this way approach to all the structures is enabled and pedestrian trajectory through block is preserved, achieving maximum accessibility and permeability of the facility. Car approaches are planned on two positions: from the streets Kralja Petra (economic access) and Uzun Mirkova.
The piazzetta, designed in front of the structure towards Knez Mihajlova street, connects structures of the complex with public space of the pedestrian zone.
