Minecraft 26.3 Iron Farm: 300, 1300 and 2270 Ingots per Hour — Schematics for 1, 4 and 8 Modules

An iron golem farm built from modules. Place one, four or eight of them: the iron from all of them flows into one storage. We built and measured all three sizes in plain Minecraft Java 26.3, with no mods or plugins.

How it works

The villagers see a zombie through a window, panic and call a golem. The golem spawns on the platform, water pushes it into a hole, it falls into a chamber with lava, and the ingots float down a stream into the chests. A piston on a clock closes the window: at night the villagers sleep, during the day they panic. In 26.3 this matters, because only villagers that have slept call golems.

The 3D view of every schematic has hints: where the villagers and the zombie go, where to pour water and lava, and which button to press.

1 module — about 300 ingots an hour

You can build it early: it pays for itself in 10 minutes.

• cobblestone — 654, cobblestone slabs — 60, glass — 16;
• chests — 12, buttons — 7, signs — 4;
• hoppers — 6, repeaters — 9, redstone — 4, piston — 1;
• beds — 3, rail — 1, torch — 1;
• a lava bucket, a water bucket, 3 villagers, a zombie, a minecart.

4 modules — about 1290 ingots an hour

Four modules around a shared storage of 12 double chests (about 41,000 ingots). A full chest overflows into the next one by itself.

• cobblestone — 2520, cobblestone slabs — 216, glass — 64;
• chests — 24, buttons — 28, signs — 16;
• hoppers — 12, repeaters — 36, redstone — 16, pistons — 4;
• beds — 12, rails — 4, torches — 4;
• 4 lava buckets, water, 12 villagers, 4 zombies, 4 minecarts.

8 modules — about 2270 ingots an hour

The same four modules on two floors. Golems from the top floor fall down a tube into the lower chamber; the storage is shared.

• cobblestone — 5500, cobblestone slabs — 408, glass — 128;
• chests — 24, buttons — 56, signs — 16;
• hoppers — 12, repeaters — 72, redstone — 32, pistons — 8;
• beds — 24, rails — 8, torches — 8;
• 8 lava buckets, water, 24 villagers, 8 zombies, 8 minecarts.

Before you build

• Build at least 100 blocks away from a village.
• Name the zombie with a name tag, or it will despawn.
• After building, press the stone button by the repeater clock once, or the window will never open.
• The schematic has no floor: place it straight on the ground.
• Place only the water sources: 16 on each module's platform and 1 in the lava chamber; the rest flows by itself.
• Do not replace the glass in the two rows by the hole with stone: golems never spawn on glass. Without it they get stuck at the rim and the farm makes 15–25% less iron.
