Something that blends in nothing castle or mansion like (though a watch tower would also work if it seemed like it was a actual watch tower and fits with the location). I would want something in Riverwood's general area (does not have to be within the town gates) that is not too large.

I am looking to have a player home there but I am a little particular about my homes. I'm starting a play through and I like the small quaint town of Riverwood.
