You've decided to find K-Space—well done, you!
K-Space can be accessed either from ground level directly, or from the main enterance of Tehnopol Küberneetika Maja. There's 2 doors to be passed for all three methods of entry. Top level doors can also be opened via Doorboy™. To confuse things even more, the doors are called front- and back-door (as hackers and hippies use the back-door). So the door naming is in reverse: front door is the "Back-door" and the back-door is the "Front door". Easy, right? Reason for this is that the Front-door (facing KBFI/NICPB) can be opened with a keyfob at all times of hour (usually).
Drones only. Please don't land your helicopter on the roof; there's plenty of room in the parking lots.
There's radio amateur equipment on the roof. The roof does not belong to k-space, there's also other equipment there.
