The front room is about the 20x30x3,00 meters although a holographic picture can visually lift the ceiling to any height above that 3 meters. So can the room be visually enlarged. There are three smaller rooms for private parties or meetings aso. However, hidden from this "main lounge" and the "private lounges" there are another 4 rooms. One of them is three quarters of the main lounge the others are smaller. They do have the latest equipement available in computers but there are also plenty of old and even older computers (some date back to the early 70's). It's partly like a museum. These hidden rooms are the hacker's lounges where most of the noted hackers (freelancers as well as CSB-staff among others) have access, exchange knowledge and (most important) hack.
