The picture illustrates the alterations that took place in two plans of a trade conference between 2009 and 2010.
Overall, the area underwent considerable transformation, becoming more comfortable for employees. The main changes took place in the structure of certain rooms and in the main hall.
In 2009, there was a main entrance in the top left side, followed by registration and a side entrance. In addition, in the southeast side of the plan, a balcony and an exhibition area can be spotted. In the bottom left, there were a meeting room next to the concert hall in front of the display area. Finally, some seats were in the concert hall while the stage was inside the meeting room.
Since then, there have been a plethora of changes. While the main entrance and the side entrance have remained intact, everything else has changed. Firstly, the registration converted into a refreshment area, and a new registration area has been constructed next to the balcony. Also, a lounge area has been added to the balcony. Moreover, the meeting room and the display area have been removed to make way for a new, bigger exhibition area. Finally, the concert hall has been replaced by the previous exhibition area.
