Here are the pictures. If you look closely there may be more than one of these sliding balconies, but one picture shows one of them where it can be slid over to where the stairs can no longer access it, however there is an upstairs door that can access it. I find this very interesting and even sneaky. If you can lock the balcony away from the stairs you ca. Lock access to both the balcony, any computers on it and if it's the only access to the second floor access to that. And also if this is how you access the tower or roof you could use this to limit access to those areas or others.. what's interesting is the wall with the sliding door and the upper door with the sliding balcony leads into said kill room, and if you look through the sliding door you can see a bench and sink that look super creepy.
