A lot of the times the other reality rooms include weirdly shaped architecture. For example they can be full of ball, rectangular-like pillars which are most common in the pool rooms. Talking about pool rooms - these rooms are one of the most wickest ones in terms of shape or architecture overall.
The image is quite popular due to its fairly weird architecture. I always get a depressive feeling from this photo - it looks like a bunch of flats are built together, if people would live in them, to their knowing they'll be stuck there forever, and instead of outside you have a small area in the center which is to touch grass, so it gives a feeling of being outside, but you are actually closed between heavy walls. This is something called the office level as this picture shows, and structure like this is quite common in there.
Backrooms has no limits on architecture. Rooms that are big, small or huge can have some of the most random holes in them like these 2 pictures show. Usually you are able to go through them - depending on how far up they are, what scale, and if you walk trough one of these, you'll most likely end up in another room which is normal. There are a quatrillion variants of these passageways - some of them can be ridiculously long, one of them leads you to the other side wheres a 100 feet fall down, and so on.
These 3 pictures show you the pool rooms. As mentioned earlier, the pool rooms have the most odd looking architecture. You can have the biggest, smallest, thickest or thinnest objects randomly scattered on the these square-shaped tile walls as this shot shows which is right above this text, down left. It doesn't matter how high up you are, you can easily fall to your own fate (even with water down below), because pool rooms can often create these balconies that have no railings at all (the first photo shows on the left). Lastly, huge frightening deep holes can be found in the pools - don't know whats down there, my imagination depicts of a monster (down below is an image).
