Igloo Seeds With Basements Worth Finding
Rare Structure Seeds · By the ChunkScan Team · Updated 2026-09-07
An igloo looks like nothing: a snow dome, a bed, a furnace, a crafting table. Half of them hide a trapdoor under the carpet that drops into a brewing lab with a zombie villager, a cleric villager, a splash weakness potion, and a golden apple. That single room is the cheapest early-game villager cure in the game and a guaranteed brewing stand before you ever see the Nether. The catch is that igloos only spawn in snowy plains, snowy taiga, and snowy slopes, and the basement is a coin flip decided per structure. This list covers seeds from our scans where an igloo sits within a few hundred blocks of spawn, so checking the basement costs minutes instead of an expedition.

What an igloo basement actually gives you
The basement is a short ladder shaft ending in a small room with a brewing stand, a cauldron, and two cells. One cell holds a zombie villager, the other a cleric villager. A chest in the room contains a splash potion of weakness and a golden apple, which is exactly the recipe for curing the zombie. A cured villager offers heavily discounted trades for life, and a cleric sells redstone, lapis, glowstone, and ender pearls. On top of that, the brewing stand saves you the blaze rod trip. For a first hour that wants a village economy without finding a village, an igloo basement is the shortcut.
How our scanner locates igloos
ChunkScan runs the same world generation code the game uses and records every structure within 1024 blocks of the spawn point, with coordinates and straight-line distance. Igloos appear only where the surface biome is snowy plains, snowy taiga, or snowy slopes, so the scanner also stores the spawn biome and the 32 by 32 biome grid around it. What the scanner does not do is generate the interior. Basement presence is rolled when the structure pieces are built, so we can tell you where the igloo is and how far you walk, but you confirm the trapdoor yourself. The listed coordinates are the structure origin, so head there and look for the dome.
Seed -9223213797371745964: an igloo 80 blocks from spawn
This is the tightest layout in the set. The igloo generates at x 80, z 0, only 80 blocks from spawn, even though the spawn biome itself is plains, which means a snowy biome edge sits right beside the starting area. A ruined portal shares the same 80 block distance at x 48, z 64, so you can loot obsidian and the portal chest on the way. Trial chambers follow at x 112, z 80. In the Nether, the scan found a bastion at x 144, z -208 and a fortress at x 80, z 256, so a portal built near the igloo lands you between both. Check the igloo carpet first, then decide whether the run is a speedrun or a base.
Seeds -9223256316579753416 and -9223017716933215523: two igloos each
Two igloos double your odds of a basement. Seed -9223256316579753416 spawns in snowy taiga with igloos at x -224, z 224 and x 288, z 112, at 284 and 295 blocks. Trial chambers sit between them at x 64, z 192, and a second chambers entrance is at x -320, z 32. Seed -9223017716933215523 spawns in snowy plains with an igloo at x 112, z -224 at 217 blocks and a second at x -432, z 96 at 440 blocks. Three ruined portals surround this spawn, the nearest at x 272, z 16. With two independent basement rolls, the chance at least one igloo has a lab rises from one in two to three in four.
Seed -9223245134574708565: igloo plus trial chambers at spawn
Spawn is snowy plains and trial chambers begin at x 16, z 16, just 50 blocks away. The igloo is at x 48, z 160, 160 blocks out on the same side of spawn. A shipwreck at x 144, z -240 and an ocean ruin at x 16, z -272 mean water lies to the north, useful for a drowned farm or early treasure maps. A village at x 320, z 176 rounds out the trading options if the igloo basement turns out empty. This seed is the best pick if you want the igloo cure and a trial chambers run in the same session without building a rail line.
Checking for the basement quickly
Walk in and break the white carpet in the middle of the floor, or the carpet directly under the bed's foot. If a trapdoor is there, the ladder goes down about twenty blocks to the lab. If there is only snow underneath, that igloo rolled no basement and you should move on. Bring a few torches and a sword: the shaft is narrow and the cell holding the zombie villager is bars, not glass, so keep the villagers apart until you are ready. Throw the weakness potion at the zombie villager, feed it the golden apple, and wait a few minutes with the room lit. The cure pauses if the zombie takes damage, so do not fight nearby.
Seeds on this list without an igloo
Not every seed rendered below has an igloo in the first 1024 blocks. Seeds such as -9223371612384761370, -9223214314906176716, and -9223024552515960696 matched the broader rare structure filters through trial chambers, ancient cities, or ocean ruins near spawn, and they appear here for that reason. Seed -9223214314906176716 for example has two ancient cities at x 160, z 144 and x 240, z -272. If your goal is specifically an igloo, focus on the four seeds named above and use the map on each seed page to confirm the snowy biome patch before you commit to a world.

Frequently Asked Questions
Do all igloos have a basement?
No. Each igloo rolls a basement with roughly a fifty percent chance when it generates. The scanner confirms the igloo's position, but you need to lift the carpet in the middle of the floor to know whether the ladder is there.
Which biomes can an igloo spawn in?
Igloos generate only in snowy plains, snowy taiga, and snowy slopes. A seed with a plains spawn can still have one nearby if a snowy biome borders the spawn area, as with seed -9223213797371745964.
What is in the igloo basement chest?
The chest holds a splash potion of weakness and a golden apple, the two items needed to cure the caged zombie villager. The room also contains a brewing stand, a cauldron, and a cleric villager in a separate cell.
