About This Guide

An efficient iron farm that uses villager mechanics to spawn iron golems automatically. Golems fall into lava and drop iron ingots into a collection system. Produces iron passively while you AFK nearby. This intermediate farm build works in Minecraft Java Edition, version 1.20+ and above. Budget around 30-40 minutes for construction — have all materials in your inventory before you begin.

Difficulty: Intermediate

The Intermediate rating reflects either multi-layered construction, a larger footprint that demands planning ahead, or simple redstone circuits. You should be comfortable with basic survival mechanics and resource gathering before starting. Budget extra time for iteration — not everything lines up perfectly the first try.

Step-by-Step Instructions

Step 1: Build the Collection System

Place a chest on the ground. Connect two hoppers feeding into the chest. This catches all iron ingots and poppies that drop from killed iron golems.

💡 Tip: Sneak-click to place hoppers pointing into the chest. Verify items flow correctly before building up.

Step 2: Build the Lava Kill Chamber

Above the hoppers, build a cobblestone-walled chamber 4x4 with lava in the center 2x2. This kills iron golems that fall in, dropping their iron through the lava to the hoppers below.

💡 Tip: Make sure lava is fully contained. One leak and your iron gets destroyed. Double-check the cobble walls.

Step 3: Build the Spawning Platform

Place a large cobblestone platform (6x5) above the kill chamber. This is where iron golems will spawn. Keep it at least 2 blocks above the lava.

💡 Tip: Iron golems need a solid platform to spawn on. The bigger the platform, the better the spawn rate.

Step 4: Add Water Channels

Place water source blocks on the platform to push iron golems toward the center drop hole. The water flows should converge to one point above the kill chamber.

💡 Tip: Iron golems cannot swim — water pushes them effectively. Make sure there are no dead spots where golems get stuck.

Step 5: Build the Villager Pod

Enclose the platform with glass walls 3 blocks high. Place 4 beds and transport 3 villagers inside. Add a name-tagged zombie nearby (visible but unable to reach villagers). The scared villagers trigger iron golem spawns.

💡 Tip: Villagers must see the zombie and sleep in beds. Glass walls let them see the threat without being hurt.

Step 6: Activate and Test

Make sure villagers can pathfind to beds and are panicking from the zombie. Iron golems should start spawning on the platform, get pushed by water into the lava, and iron ingots appear in your chest.

💡 Tip: If golems aren't spawning, check that villagers slept at least once and can see the zombie. The farm works within 128 blocks.

Run the farm AFK for 20–30 minutes after building to stockpile a large initial batch of resources.
Take a screenshot of the finished build from multiple angles — you’ll thank yourself when you want to recreate it in a future world.
Label a nearby chest with a sign so you can dump leftover materials immediately and keep your inventory clean.
