This might not be all that proper answer. Surely it doesn't answer your question, but I think this could pass.
At least if you are looking to do this based on existing funiture and apartment, which you are not specific about.
If you want premade images of furniture and other objects, problem is that we don't live in a society where people live in identical houses. So, the odds of you finding completely identical sofa, table, lamp, bed and most of the stuff...are very slim. Especially when we are talking about illustration of these objects which would also have to have about the same style.
If it's just imaginary setup, then I take it back.
So I felt bad not answering the actual question and googled around for "Interior design software" and who would've guessed autodesk had something just like that.. :)
