Hey Eddie,
what exactly are you trying to reach? What kind of level design or what kind of game. There are several techniques and tutorials out there, so you should specify, what you want to be your goal 
I’m making a first person shooter
I’m wondering in what context you mean “set up my room” You mean the raw geometry?
I would make rough sketching with primitives and later recreate that geometry in your favourite 3d modeling environment.
