I'm fortunate to have a rather large 'dorm' room.
My dorm room has lots of book shelves. Invariably, I'll acquire more books and so will be needing even more book shelves; I'll probably end up with a sort of Room of Requirement hidden area ...
But in the meantime, my dorm room has lots of windows. Being a professor, I've a room to myself which is good, because I've claimed all the windows for shelves for my plants. Aloe Vera, Christmas Cactus, Angel Wing Begonias, Orchids, African Violence (a pugilistic form of African Violet -- they need to be kept space out from each other and from other plants), Amaryllis, and other plants festoon the shelves and tables by each of the windows.
Oh, right -- there's a closest, it's walk in with a very closable door. There are absolutely no bright and shiny bits anywhere on the door. (Note: none of the plants have pots which have anything bright and shiny about them. In fact, there is very little which is bright and shiny in the room, except in one small area ....)
My bed is nice. It's king+ size. If I'm lucky, I get the outermost edge of it. My Crup somehow grows mega huge (even if she weighs only 15 pounds) and hogs the bed.
Well, more than her are here sometimes. I don't have any other critters living with me full time .... just a couple (or few) who are recovering from being injured or who need a bit of extra attention before going back out to the wild. (Yes, that house-breaking spell is priceless!) They each have their own beds, but somehow I start out in the middle of my bed at the beginning of the night and wake up on the edge of it, and everyone else is sharing it with me.
Not my bed but you get the gist of how much room is available for me come morning time --
