Materials You’ll Need

Before you begin, gather the following items:

  • Beds: 3
  • Blocks (any solid material): ~100
  • Slabs: 10
  • Trapdoors: 3
  • Water buckets: 2
  • Lava bucket: 1
  • Signs: 4
  • Villagers: 3
  • Zombie: 1 (preferably in a boat for easier management)
  • Hopper: 2
  • Chest: 1
  • Glass (optional): For aesthetic purposes.

Step-by-Step Guide to Building the Iron Farm

1. Find a Flat Spot

Choose a flat area away from other villages or iron farms. This ensures that your farm works efficiently without interference.

2. Dig a 7-Block Deep Hole

Dig a 5x5 hole that is 7 blocks deep. This will act as the foundation for your farm.

3. Create a Room

At the bottom of the hole, expand one side into a 5x5 room. This will be where villagers and the zombie reside.

4. Place Beds

Position three beds in the room with their pillows facing the open sky. This step is crucial as the villagers need to "see" the sky to link with the beds.

5. Add Slabs and a Trapdoor

Place slabs around the room to prevent mobs from spawning. Add a trapdoor above the beds to allow villagers to stay safe while still interacting with the farm.

6. Dig Out a Smaller Room

Next to the larger room, dig a smaller 3x3 space. This is where you’ll place the zombie.


7. Add a Torch and Boat

To keep mobs from spawning, place a torch in the smaller room. Then, place a boat and trap the zombie inside. The zombie will scare the villagers, prompting iron golem spawns.


8. Build the Kill Pit

Above the villager area, dig a 5x5 hole where the iron golems will spawn. Line this area with water to funnel golems into the kill chamber.

9. Install a Collection System

Place hoppers at the bottom of the pit, funneling into a chest. This will collect iron and poppies from the iron golems.


10. Create the Kill Chamber

Build a 2x2 area with signs placed on the walls. Pour lava above the signs. The lava will kill the golems while keeping their drops intact.

11. Add Villagers and Zombie

Finally, bring three villagers into the large room and ensure they link to the beds. Place the zombie in the smaller room. Make sure the zombie can "see" the villagers without being able to harm them.

How the Farm Works

The villagers, scared by the zombie, trigger the iron golem spawns. The golems appear in the designated spawn area and are funneled into the kill chamber. Their drops are collected by the hoppers, ensuring a constant supply of iron.


Tips for Success

  • Use name tags on the zombie to prevent it from despawning.
  • Keep the farm far from other structures to avoid interference.
  • Regularly check the collection chest to ensure the system is functioning properly.

With this setup, you’ll have an efficient iron farm that works day and night. Enjoy your endless supply of iron and focus on building your Minecraft empire!
