The vendor buildings were interesting in that they had nap rooms apparently due to staff being there 24x7 to do support, and they also had lots of lockers maybe due to vendors not allowed to bring recording devices inside the building (which includes phones), they were probably also helpful for people who bring scooter helmets which may not fit at their small desk.
We went to see NETP (2 buildings), WCC, and UBT1 which had 10 different floors. The density was also quite high, but when we came to visit not too many people were working, it was probably a quiet time.

Some pictures:

nice padded elevator in case you go insane :)

nap rooms, called snug rooms

lockers for each person working there
