Version 1: a big boring room with a cage
This was the original room, have a big factory like room with a cage in the middle. After creating it it... just wasn't. Progress stalled after that for a month or so.
Version 2: a white room
Away with the factory! In with the white room! Much more clinical, and much more suitable! This version started to work, but felt artificial at the same time.
Version 3: a darkened white room
To combat artificiality I removed the light and added more atmospherics (a typical thing I do, apparently ;) ) -- and that worked, but it also started lacking that clinical feel. We also removed the cage, as it detracted instead of added.
Version 4: back to white!
.. but with atmosphere! This works better, but the floor.. isn't. And the walls aren't either.
Version 5: changing the walls and floors
There's actually a version 6..9 too, but I won't bother you with those details.

Burn after use!
