Hey! I'm so sorry about not replying to this!! I got notification about it! The building would overall be very high tech, with automatic sliding transparent door, etc. But some rooms are worn out, the Institute being there so long. The one all of us are in is a bit worn out. What everyone else said is correct too. Very few rooms are like a an asylum type thing, to keep special patients' powers unusable while they're in that room. I don't know what the room is called. Its like the walls are foam, or mattress like material and soundproof.
I hope I answered everything! :)
