REDSTONEPEDIA › Farms › Iron farm
Day-1 iron farm (iron armour on your first day)
353 iron an hour · 827 blocks · 0.43 an hour per block · 17 iron to build · bed-plate farm with its chute to the side, dug 11 deep
Villagers scared by a zombie summon iron golems; the farm kills them and collects their iron in a chest.
To build it: 17 iron in hand, 12 buckets of lava and 3 villagers from the village. Starts by itself the first night. Restarts by itself when you come back after days away.
55 minutes from the first block to a full set of iron armour, then 353 iron an hour · needs no redstone

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, under the last hopper, collects the iron. In the game, build it and wait near it.
How this design does it: 1 module(s); each: 2 scared and 0 blind villagers in 1-cell pods, a zombie in a boat, the bed plate; golems spawn on a 6x6 pad 7 below the beds and fall through its dry hole into a drop to 20 below the beds, then a water channel 16 blocks to the side through the rock, to a lava blade beside the farm.
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 (12 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, under the last hopper, collects the iron. 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 | 0.43 | iron ingots an hour for each block you place |
| iron per hour | 353 | iron ingots an hour |
| golems per hour | 88.5 | iron golems an hour |
| seconds per golem | 40.7 | the time between two golems |
| modules | 1 | groups of villagers that each summon golems on their own |
| iron per hour per module | 353 | iron ingots an hour for each group of villagers |
| kill | 27.5 s | how long a golem lives before the farm kills it, at the longest |
| kill tail | the longest 32.4 s: no golem outlived 1 min in 13,501 golems (95% bound 0.02% a golem) | |
| golems at the zombie | 0 of 13,501 golems targeted the farm's zombie | |
| 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 327 iron/h; rain day 333 iron/h; thunder day 335 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) about every 10,639 game days; site note: a fire on the site that cannot reach the farm about every 7.6 game days; AFK spot struck: about every 1,627 game days (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 about every 1,587 game days (every 23 game days of thunder; a lightning rod topping its column within 128 blocks prevents it); a skeleton trap horse that triggers (within 10 blocks of the AFK spot) about every 3,903 game days (a lightning rod within 128 blocks topping its column takes the bolts: none then); the farm breaks in about 10,639 game days (a fire reaching the farm first); 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 | 1.1 | iron lost for each hour of thunder |
| sunburn | never (the zombie never sees the sky) | whether the zombie can burn in daylight |
| fire | never | whether the lava can set the farm on fire |
| bill | 17 iron, 0 quartz, 3 villagers, 3 beds, 1 zombie | what it costs in survival: iron (hoppers, the bucket and every tool you need), quartz, villagers, beds |
| payback | 3 min | how long the farm takes to make back the iron it cost |
| build time | 49 min at day-1 prices (158 placed with 3 cobblestone slabs capping stray golem spots and 18 cobblestone seals, 829 dug, 3 lava trips, 3 villagers moved; the most: 829 dig 829 s, 3 villager_moved 540 s, 3 lava_trip 360 s, 3 extra_bucket 270 s, 1 zombie 180 s, 158 place 158 s, 1 hopper 154 s, 1 tool:bucket 90 s) | about how long the build takes: placing and digging its blocks, fetching the lava, moving the villagers in |
| time to an iron kit | 55 min at the cheapest spot (from dawn of day 1 until the chest holds 24 iron; runs 54-57 min; 55-56 min over the 12 nearest spots) | about how long from starting the build to a full set of iron armour (24 iron), its own iron counted |
| build minutes | 49.0 | |

| volume per module | 12,210 | |
| entities alive | 5.7 | |
| entities peak | 9 | |
| tools | bucket 3 + extra buckets 9 | 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 |

| chunk columns | 3 | how many 16 x 16 chunk columns it covers |
| storage | 4.6 h (32 slots; 83 poppies/h) | how long its chests and hoppers hold the iron and poppies before they fill |
| hoppers per 1000 iron/h | 3.0 | hoppers for each 1000 iron an hour: each hopper costs the server a little work every tick |
| spot | village-edge at -343 61 244 (the cheapest of the 12 nearest valid spots) | |
