Why do I have no guns? Do they just disappear from my house magically, or are they stolen? Because my house has guns. Lots and lots of guns.
And is in the middle of nowhere, so few zombies to worry about. And is in the loop of a river, with only a small bridge reaching my farm and house.
Which has three stories, one of which can only be accessed by ladder. My house is ideal for a zombie outbreak. Much more than a week's food, plus we grow our own vegetables and fruit so they'd keep us alive. We have our own water and power supplies, meaning running hold and cold running water and electricity. Plus we have lots of barbed wire to block off the fields near the thinner points of the river, in case some zombies float over.
I'd just knock down the bridge, use the rubble to fill up the smaller bits of the river, with barbed wire, fill up the fields next to said thinner bits of river, and put on the lights that line our house and garden at night. One guy awake with one of our rifles would cover the occasional zombie who might ever come near us, since we're so far from towns or anyone else.
In terms of proper defense, I'd lock our front porch door. Seriously, it's eight feet tall, massive, solid, eight-inches of wood through, no zombie's getting in there. I'd use the many planks we have on the farm, plus machinery and other equipment to board up the larger, more breakable windows, and just cover the smaller, thicker ones.
I'd set up tiers of defense too. First tier would cover the front of our stairs and the end of a big corridor with furniture/junk, and fill up a doorway or two on the way down the corridor, then end at the end of the corridor, in the kitchen. It has a big window that could be broken, but the walls of our house are solid stone and unbreakable by zombies. Then I'd have a junk barricade on the curve of my stairs, where it meets the landing, as a small rope would be sufficient to pull people up onto the landing from there, plus it would be a fine place to keep lookout from. That area leads out onto our escape route, a flat roof, which we'd connect with planks to the tree mere feet across from it. It is part of a row of trees which can literally be walked down to the cottages, our backup hideout. They appear rundown, but are habitable and sturdy.
If they got up the stairs, which they wouldn't. We have a small cement mixer plus lots of sand and gravel, so a lot of thick cement would block off the stairway to the ceiling, and the only way up would be by the rope, which would be lowered to raise people up. However, if, and we could not escape, I'd have tier three in the attic. It is only accessible by ladder, can house our whole family easily, and has space to stock our guns and supplies, which include numerous melee weapons too. Zombies get up there... we're fucked. But they wouldn't. Since only about ~10 people live within about twenty miles of us, I don't think we'd ever have to retreat past the front door, let alone to the attic.
I've spent a bit too much time thinking about this haven't I?
