The "hut" has been abandoned and is in serious disrepair: see this photo from December 2011. Most of the tiny cabins (just big enough for a couple of very close friends to sleep in) alongside the "hut" are also falling apart. (Three looked in excellent condition; didn't see the inside since they were locked.)
This picture is an old one indeed. I know there was an project ongoing to repair it and I'm not sure if they finished it even today. Currently it probably looks like in your picture. I don't know for sure cause I always used the west entrance lately. Most people seem to do the same.
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
