Help! What do I do with my stock rental agency studio suite?? Desperate.?

I have lived in this suite for the last two years and this year the lack of any architectural separation in the room is driving me insane as I keep trying to create different 'zones' with what miss matched pieces of furniture I have. I enjoy the concept of studio living, but am beginning to feel trapped. I can't get up and move away from something because everything is *right there*. Also, there's the expanse of stock gray carpet and the featureless white walls (which I have finally been given permission to paint) I just want to add some actual architectural detail in the room so I feel like I am actually moving into different parts of the apartment. It is a large space, able to fit my futon set (which is also my bed), my medium art table, a full length dresser, canadian tire shelf, maple coffee table and maple desk with three antique victorian chairs (one large, two smaller) as well as one very tall fake plant. Even *with* All of this there is are two large empty corners, one of which i want to put a small single bed. I'm trying to obtain a non claustrophobic cozy feel with some character suite feel to it. I don't want to live in a faceless apartment anymore. I also want to add in some sort of permanent bed (which will have to be a single) Also, I've just started a new job and am saving up for art school in september so budget is really limited, so I'd prefer DIY stuff and creative arrangements as opposed to going out and buying something for hundreds of $'s. Can anyone help??? *Any* suggestions are appreciated, and even if you have images to creative small studios it might give me some ideas:)
