I study everywhere in my house.
My house is all open living, so even though I'm in the study I can still hear the episode of SpongeBob Squarepants my sister is watching in the lounge atm.
Also, when I'm very busy with study (e.g. close to exams) I tend to take over the whole house... I might have accounting sprawled all over the kitchen table, economics piled onto the desk in the study and Japanese on the coffee table in the lounge. My Dad knows how important my study is to me, so he usually just puts up with it.
I study in bed occasionally as well, and on nice days I study on the veranda.
I find changing rooms to be helpful... my study can actually get a bit stagnant if I keep trying to study in the same room all the time.
