You’re tired of digging. Honestly, we all are. You spend three hours strip-mining at Y-level 16, dodging gravel and listening to the distant, muffled groans of zombies, only to come back with maybe two stacks of iron ore. It’s depressing. Then you realize you need hoppers for your storage system. You need rails for your nether hub. You need buckets, anvils, and shields. Suddenly, those two stacks of iron are gone in four minutes. Building an iron farm in minecraft isn’t just some "pro-gamer" flex anymore; it is a fundamental survival requirement if you actually want to play the fun parts of the game without a pickaxe permanently glued to your hand.
Most people overcomplicate it. They look at these massive, sweeping technical designs from guys like Gnembon or IanX0four and think they need a PhD in villager pathfinding just to get a single ingot. You don't. The mechanics are actually pretty logical once you stop treating villagers like people and start treating them like specialized spawning anchors.
The weird science of golem spawning
Iron golems don't just "show up" because a village is peaceful. They are essentially a security response. In Java Edition, villagers need to gossip or be in a state of panic to spawn a golem. Specifically, they need to have slept in the last 20 minutes and they haven't seen a golem nearby recently. If they see a zombie? They freak out. When they freak out, they check a 16x13x16 area around them for an existing golem. If they don't see one, the game says, "Okay, send in the muscle," and a golem spawns on the highest available solid surface.
Bedrock Edition is a completely different beast. It’s way more finicky. You need at least 10 villagers and 20 beds. No zombies required there—just a lot of beds and a lot of professions. If 75% of those villagers have worked at their workstations in the last day, you get iron. If you’re playing on a console or the Windows Store version, stop trying to use zombie-scare tactics. It won’t work. Stick to the "mass employment" strategy.
Why your farm probably isn't working
If you've built a farm and nothing is happening, it’s usually one of three things. First, the villagers can't sleep. They don't need a full night's rest, but they must be able to pathfind to a bed and technically "touch" it for a split second to reset their internal timer. If their eye line is permanently blocked by the zombie, they stay panicked forever and never reset.

Second, the "search radius" is cluttered. If a golem spawns on a random blade of grass outside your collection pod because you built the farm too close to the ground, the villagers will see him, feel safe, and stop producing. You have to spawn-proof the surrounding 10-15 blocks with slabs, buttons, or just build the whole thing high up in the air.
Third? Line of sight. The villagers need to actually see the zombie to get scared, but they also need to be able to break line of sight to go to sleep. Use a compost bin or a cauldron for the zombie to stand in. It keeps them at the right height so the villagers catch a glimpse of their rotting face every few seconds as they bob in water, but not so constantly that they lose their minds and forget how beds work.
Building the basic Java "scare" farm
You don't need much. Grab three villagers—kidnap them from a nearby village with a boat or a minecart. You’ll need three beds, one zombie, a name tag (so the zombie doesn't despawn), and some lava.
- Elevation is your friend. Build a platform about 20 blocks off the ground. This ensures no golems spawn on the floor below.
- The Villager Pod. Build a small 3x3 room with three beds. Replace the floor under the "head" of the beds with top slabs so the villagers can see out but can't escape.
- The Zombie Cage. Place a zombie in a cauldron or a compost bin about two blocks away from the foot of the beds. Put a roof over the zombie so he doesn't burn up when the sun comes out.
- The Killing Floor. Directly above or adjacent to the villagers, create a 5x5 spawning platform. Use walls (not fences) to keep the golems contained.
- The Disposal. Put signs on the walls to hold up a layer of lava at head-height for a golem. Underneath the lava, put water flowing toward a hopper.
Golems are three blocks tall. The lava kills them because it hits their head, but the iron ingots drop at their feet—in the water—where they stay safe from the fire and flow right into your chests. It's efficient, it's brutal, and it's the fastest way to get rich.

Dealing with the Bedrock Edition headache
Look, Bedrock players have it rough here. You can’t just scare three guys with a zombie. You basically have to build a mini-city. The most reliable method involves a 21x21 platform. You need to place 20 beds in a very specific pattern, usually in a pit under the floor, and ensure 10 to 20 villagers have workstations like fletching tables.
The biggest mistake on Bedrock? Cats. Cats spawn before golems do. If your farm is filling up with string instead of iron, you need to tame four cats and sit them down around the farm. This fills the "cat cap" for the area, forcing the game to skip the cat-spawn check and go straight to the golem-spawn check. It sounds like a myth, but it’s a hardcoded mechanic.
Advanced tweaks for maximum rates
If you want to go beyond the basic "one-pod" design, you can stack these units. However, you have to keep them at least 10 to 15 blocks apart so the village detection zones don't merge. If they merge, the game gets confused about where the "center" of the village is, and golems might start spawning in the air or inside walls.
- Glass is your best friend. Golems cannot spawn on glass. If you’re worried about them spawning on top of your redstone or your roof, just cover everything in glass or slabs.
- The Name Tag trick. If you can’t find a name tag for your zombie, give him an item to hold. If a zombie picks up an item (like a dropped piece of dirt or a spare chest), they generally won't despawn. Not all zombies can pick up items, though, so keep dropping stuff until you find one that's "smart."
- Lightning protection. A single lightning strike can turn your entire villager population into witches. If that happens, the farm dies instantly. Put a lightning rod about 10 blocks away from your farm, or build a large roof very high above it.
The ethics of the iron farm
People joke about villager trading and iron farms being "unethical," but let's be real. The alternative is clicking on gray blocks for ten hours a week. By automating an iron farm in minecraft, you're actually freeing yourself up to do the creative stuff—the massive builds, the complex redstone, the exploration.

A single-pod Java farm will net you roughly 300-400 ingots per hour. That’s more than enough for a solo player. If you're on a server, you might want a quad-pod design, which can push 1,200 ingots per hour. At that point, you aren't just making tools; you're building with iron blocks as a primary construction material.
Moving forward with your production
Once the iron starts flowing, the game changes. You stop worrying about losing your gear in the Nether because you have ten backup sets waiting in a chest. You start building massive rail lines to find rare biomes.
The next logical step after securing your iron supply is to link this farm to a villager trading hall. Since you already have the villagers and the iron, you can craft buckets to trade back to toolsmiths or use the iron to fuel a massive expansion of your base. Just make sure you keep the trading hall at least 64 blocks away from the iron farm. If you don't, the beds in the trading hall will interfere with the "village center" of the farm, and the golems will stop spawning entirely, leaving you with nothing but a bunch of confused NPCs and a very lonely zombie.
Check your distances. Spawn-proof your ledges. Secure your zombie. Do these three things, and you'll never touch a stone pickaxe again. It's time to stop mining and start engineering.
