Something just big enough for me and what I currently own. I'm not vain, nor do I want more house to care for than I have time or means to do so. Two bedrooms, one large enough for my bed, dresser, and computer, and one to hold my retro gaming stuff and bookshelves are enough. One bathroom, a living room large enough for my couch, recliner, end table, and a floor lamp, and a kitchen large enough for a table.
Reasonable expectations for a house with only one or two occupants, I would say.
Put all of that together in a log house and I would be the happiest man in the world, but I'll take it in any format. As for the surrounding area, all I ask is sufficient room to park my car, quiet or no neighbors, internet availability comparable to what I have now, and without a road running right in front of my place for traffic noise to disturb me.
