A Minecraft Iron Farm is one of the most valuable automated farms you can build, providing a continuous supply of iron without the need for mining. By using villager and zombie mechanics to spawn iron golems automatically, the farm generates iron ingots and poppies that can be collected with minimal effort. Iron is essential for hoppers, rails, anvils, tools, armour, and countless Redstone contraptions, making an iron farm a must-have for both survival and technical Minecraft worlds. Follow the guide below to build an efficient Minecraft Iron Farm and enjoy a reliable source of one of the game’s most important resources.

How to build a Minecraft Iron Farm
Here we will explain in detail how to build an iron farm in Minecraft. Please follow the instructions carefully.
- Start this build by creating a 26 × 26 block path square (a path is created by placing a spade on a block instead of breaking it).
- Next build a 3 × 3 stone square with a 1 block gap in the middle of the path square as shown.
- Place 2 glass blocks either side of the hole.
- Place 1 block 2 high in the middle behind the hole, as shown in the picture.
- Place blocks on top of and behind the glass blocks to form a 2 × 3 block platform.
- Next place blocks 1 high to form a 4 x 5 block square leaving off the corners and leaving a 3 x 3 block square empty in the middle.
- Place glass blocks on top of the stone blocks in a 4 x 3 block formation leaving out the top corners and leaving a gap of 1 block as shown.
- Place stone blocks on top of the glass blocks in a 4 x 3 block leaving out the corners as shown.
- Place 3 beds inside the 3×3 block space.
- Persuade a zombie into the 1 block hole (you will need to take out the block above the hole and then replace it once the zombie is in) and keep him there by placing a nametag on him – I called mine Bob!
- Place a torch in front of the beds.
- Place a trapdoor on top of the stone block that doesn’t have a glass block and then another one directly above it.
- Place slabs on top of the stone blocks (this stops iron golems spawning outside of the build).
- Place stone blocks to cover the top of the build as shown 7×3 blocks.
- Place 3 stairs across the end of the build above the zombie.
- Place stone fences around the top of the build and down the front at the zombie end.
- Place 3 buckets of water against the fences so that the water runs towards the stairs.
- Dig a trench 3×3 block and 1 deep out from the zombie end of the build.
- Dig a further 2 blocks out from the middle of your 3×3 block trench.
- Place 2 chests as shown.
- Place 9 hoppers connecting to the chest in the 3×3 trench.
- Continue the fences so that they surround the hoppers 1 block above.
- Place signposts on the fences as shown as well as one on the stone block behind the zombie.
- Place a signpost on top of the middle hopper (remember to crouch or you’ll be chasing the signpost through the hoppers to the chest).
- Place a bucket of lava on top of the middle signpost (the surrounding signposts should keep it in place providing they are in the correct place).
- The last step of the build is to get 3 villagers into the beds (this may take a little time).
- As you can see if it is working correctly the Iron Golem will spawn on top of the build in the water and slide to the edge.
- Once the iron golem slides through the water it will land in the lava.
- If you check in your chest after, you will find iron ingots and poppies.
Hints and tips for building a Minecraft Iron Farm
Common problems and solutions
- If you have Lava flowing everywhere this will mean that you have placed your signs incorrectly.
- If Golems are spawning in the wrong place you will have to double check where you have placed your slabs.
