Hi Galen, moving home is always a challenge. I am not going to wish you luck because I am certain that it is a very well thought out decision, weighing all the pros and cons. I can only congratulate you on this new step in life.
About the question, I think that to feel at home I only need good company, some books and music.

You say three things that I agree with when it comes to making a house a home; I think I'd not want to be without any of those three.
I suppose that for some people these three things are not enough and for others it is everything (or almost everything). I think the years give a good perspective of what is essential and what is superfluous.
