We are located at the TU Wien main building  at Karlsplatz! You can only pay in cash!

Our office is located in the rooms of the students' union (HTU), adjacent to a room called HTU-Großraum,

The easiest way to find us is to follow these instructions:

  1. In the TU Wien main building at Karlsplatz 13, go to the first courtyard
  2. Enter HTU Großraum (room code ACEG44) on the ground floor.
  3. At the back of HTU Großraum you will find our Buddynetwork office (room code ACEG45)

follow Fynn and Natalia to the office (video) 

If you get lost, follow the blue signs leading to HTU or ask people for the HTU-Großraum (random people usually know this room, but unfortunately they don't know us).

Office hours

Our regular office hour is every Tuesday, 18:00 to 19:00 
There are no office hours during summer.
Additional office hours are announced here on our website.

Please note that outside of the office hours, there is usually nobody in the office. Generally, we have office hours once a week during the semester but during the lecture-free time (holidays) the office hour is usually not held.
