I've lived almost all of my life on a farm way out in the mountains of the rural South. While being prepared for a break in at night is a good idea, that sort of crime is rare. The most likely threat is going to be from someone simply knocking on your door, day or night, and sizing you up. If they don't sense any vulnerabilities, they'll most likely fade away with some kind of trivial excuse to explain why they came to your door, leaving you with nothing more than a bad taste in your mouth and perhaps a bit of suspicion, unless you have the bad luck of a truly desperate criminal stumbling upon your door step.
Put more bluntly, it's fine to sleep next to a rifle and a shotgun and be ready for anything, but all that preparedness is wasted if you assume that the stranger knocking on your door is a friend you haven't met.
By designing your own house, you can avoid the flaws inherent in many older homes where windows are situated in such a manner that the person answering the door is more exposed than the person knocking on it. The safest policy would be to ignore a person knocking on the door late at night, but I could have stock escaped out in the road, or it could be a neighbor or a family member in trouble, although, usually those people would know to call me first.
A flaw with much of modern architecture as well is too much glass. A person on the outside of a lighted home can see inside, but you can't see out.
An instinct I've seen displayed too often in rural people, especially new people, is the tendency, when something makes them nervous, to turn all of the lights on, and stand in front of them. Darkness is your friend. Use your lights for a specific purpose you can articulate and not to reduce your own tension.
From a public relations standpoint and as a matter of expense, I don't think I'd be interested in putting a fence around my house elaborate enough to hold off intruders. I'm running miles and miles of fence to hold in cattle and that's expensive enough. I've nothing against creating a fortress. I just think you'll be better off if your home doesn't look like a fortress.
