Overall, the hall has been renovated during the given time frame to serve more requirements, with the introduction of new amenities, which came at the expense of a reduction in the size of car parking.
Looking at the conference hall, rooms and hall remained stable in both years. On its right side was parking used for cars, which has also been changed to industry and increased in size.

On its left corner is the IT course, which has been newly built, while Canteen and kitchen has also been built in this area. The three meeting rooms added and game room has been upgraded in 2020.
