Spear tower 5 star luxury hotel is a project made by students Milica Stankovic and Vuk Djordjevic from the Belgrade University of architecture located in Serbia, for their 3rd year of study. The main idea was to create a high-rise hotel which will represent a land-mark in Belgrade where it is situated. The tower is 201 meters tall and has 80 000 square meters of space. The structure itself consists of the inner core and the outer shell which in this case is a chamfered triangle rotated around the inner core while supported by 7 equally rotated trusses. In this case the green floors which are repeated on every 6th floor of the skyscraper. The extended green floors are open-space gardens opened not only to the guests but also to the visitors of the hotel. The gap between the inner core and the 7 extended trusses provides an excellent source of natural ventilation to the building.
 The hotel itself has 4 restaurants, 3 bars, a large conference area, a wellness center, an art gallery, a library, several shopping areas, an administration area and over 250 rooms.
