REDSTONEPEDIA › Farms › Iron farm
Middle-ground iron farm (the most iron for an evening's build)
1,700 iron an hour · 4,207 blocks · 0.40 an hour per block · 66 iron to build · farms around one kill chamber
Villagers scared by a zombie summon iron golems; the farm kills them and collects their iron in a chest.
1,692 iron an hour on a rainy day, 1,699 in a thunderstorm. Nether quartz: 12; iron: 66. Fits in 16 chunk columns: 58×47×58. Restarts by itself when you come back after days away. Its storage holds 9 hours of iron.
1,696 iron an hour from a 107-minute build

Try it
Press play to watch it work: the villagers sleep at night and panic at the zombie by day, golems spawn and die, and the hoppers carry their iron to the chest; the top right counts the game's time, the golems and the iron. The magenta floor is where a golem can spawn, seen through the blocks (Spawn spots hides it). The chest tagged OUT collects the first copy's iron; every copy has its own chest under its last hopper. In the game, build it and wait near it.
How this design does it: Farms around one kill chamber.
Build it
Download .litematic Download the design as text
The .litematic opens in Litematica (Minecraft 26.3): every block of the design in one region. The text file is the same build written as plain text, block by block.
Pour in the water and the lava (16 bucketfuls) where the view shows them.

Details: how it works, measurements and properties
In depth
villagers scared by a zombie summon iron golems; the farm kills them and collects their iron in a chest
How to try it
Press play to run the farm. The villagers sleep in their beds at night and panic at the zombie by day, golems spawn, fall and die in the lava, and the hoppers carry their iron and poppies to the chest. The chest tagged OUT collects the first copy's iron; every copy has its own chest under its last hopper. The top right shows the game's time, the golems so far and the iron in the chest; the speed menu plays it faster or slower. Drag to look around, pinch or scroll to zoom.
Measurements
On Hard, through rain, thunder and lightning.
| metric | value | what it means |
|---|---|---|
| iron per hour per block | 0.40 | iron ingots an hour for each block you place |
| iron per hour | 1,696 | iron ingots an hour |
| iron range | 95% 1688-1705 | the range its rate falls in, 95% sure |
| golems per hour | 426.5 | iron golems an hour |
| seconds per golem | 8.4 | the time between two golems |
| share of ceiling | 89% | how close it comes to the game's limit: one golem every 30 seconds for each group of villagers |
| modules | 4 | groups of villagers that each summon golems on their own |
| iron per hour per module | 424 | iron ingots an hour for each group of villagers |
| kill | 25.75 s | how long a golem lives before the farm kills it, at the longest |
| kill tail | the longest 30.7 s: no golem outlived 1 min in 68,247 golems (95% bound 0.00% a golem) | |
| golems at the zombie | 0 of 68,247 golems targeted the farm's zombie | |
| neighbour sightings | 534 of 68,247 golems sensed by another group (534 sensings, 0.01 a golem) | |
| lips | none (no golem stands dry beside a current) | |
| restarts after a missed night | yes | whether it starts again by itself after a night its villagers could not sleep (rain at dusk, a storm, you away) |
| restarts after days away | yes (unloaded or not ticking | whether it starts again by itself when you come back after days away |
| back | by day or at night: the first golem 0.0-0.1 h after the return) | |
| rain | clear day 1,709 iron/h; rain day 1,692 iron/h; thunder day 1,699 iron/h | iron an hour on a clear day, a rainy day and a stormy day |
| lightning | about 0.0 iron lost per thunderstorm; no villager ever turned into a witch; the zombie's boat broken never; a fire that can reach the farm (its flammable blocks or mobs or drop path) never; site note: a fire on the site that cannot reach the farm about every 12 game days; AFK spot struck: never (a 7 x 7 opaque non-flammable roof over the player's column with its block 4 above the player's feet prevents it: a single block over its column does not); no natural flammable block lies on a fire's way to the farm; a skeleton trap horse on the farm never; a skeleton trap horse that triggers (within 10 blocks of the AFK spot) about every 9,293 game days (a lightning rod within 128 blocks topping its column takes the bolts: none then); lightning never breaks the farm; thunderstorms 1.4% of the time (5 min 10.55 s each on average) | what thunderstorms cost: the iron a strike burns, and how often a strike turns a villager into a witch, breaks the zombie's boat or starts a fire |
| thunder loss | 0.0 | iron lost for each hour of thunder |
| sunburn | never (the zombie never sees the sky) | whether the zombie can burn in daylight |
| fire | burns its glow_lichen (first at -267 35 273) in about 0 min in 72 of 96 runs; the lava then flows in | whether the lava can set the farm on fire |
| bill | 66 iron, 12 quartz, 16 villagers, 16 beds, 4 zombies | what it costs in survival: iron (hoppers, the bucket and every tool you need), quartz, villagers, beds |
| payback | 2 min | how long the farm takes to make back the iron it cost |
| build time | 107 min at day-1 prices (1,579 placed with 72 cobblestone slabs capping stray golem spots and 3 glass caps in water and 476 cobblestone seals, 4,069 dug (the stair down to the chest: 108 dug, 6 placed), 1 lava trips, 16 villagers moved; the most: 4,069 dig 2,034 s, 1,579 place 1,579 s, 12 hopper 624 s, 4 zombie 480 s, 14 villager_bred 420 s, 2 villager_moved 240 s, 16 red_bed 157 s, 8 comparator 136 s) | about how long the build takes: placing and digging its blocks, fetching the lava, moving the villagers in |
| time to an iron kit | more than 3 game days in 8 of 8 runs | about how long from starting the build to a full set of iron armour (24 iron), its own iron counted |
| build minutes | 106.7 | |
| t kit minutes | none | |
| collecting | 18 s per trip to the chest (2 x its depth, 37 layers | |
| at | the access's speed) | |
| iron per hour sleeping | 1,718 | |
| volume per module | 39,527 | |
| entities alive | 27.2 | |
| entities peak | 32 | |
| tools | bucket 3 + iron pickaxe 3 | the tools you need and the iron each one costs: a bucket for lava and water, shears for leaves, an iron pickaxe for redstone dust |
| lava sources | 16 | lava source blocks to bring: one bucket trip each |
| materials | Nether: quartz in 12 blocks | the stage of the game its materials need: day 1, the Nether (quartz, slime, magma...) or the End |
| chunk columns | 16 | how many 16 x 16 chunk columns it covers |
| storage | 9.1 h (303 slots; 423 poppies/h) | how long its chests and hoppers hold the iron and poppies before they fill |
| hoppers per 1000 iron/h | 7.1 | hoppers for each 1000 iron an hour: each hopper costs the server a little work every tick |
| spot | plains at -276 54 220 (the cheapest of the 12 nearest valid spots) | |
