An igloo is an uncommon structure generated in snowy taigas, snowy plains, or snowy slopes and built mainly of snow blocks. Some igloos contain hidden…
An igloo is shaped like a small dwelling made of snow blocks. It has an entrance without a door and a carpeted interior containing a bed, furnace, and crafting table. There are two windows made of ice blocks[JE only]/packed ice[BE only][1] and one redstone torch as a light source.
Igloos that generate without a basement have a snow block in place of the trapdoor. The villagers, the brewing stand, and the chest are absent in this case.
If an igloo with a basement forms partially above open-air, the shaft with the ladder still generates.
In Java Edition, the generated villager is always a cleric and is a plains biome type, but becomes unemployed after one tick due to not having a workstation. The villager cannot pathfind to the brewing stand or cauldron to take on a profession unless some of the blocks confining it are broken. The generated zombie villager always has the profession of cleric and becomes unemployed if cured.
In Bedrock Edition, the villager is the snowy type with a random profession. The zombie villager is unemployed but can change its profession to cleric or leatherworker after being cured because it can claim either the brewing stand or the cauldron.
Sometimes if igloos generate at low altitudes(-30 or lower), their basement may break bedrock allowing the player to access the void.
One may access the individual structures of an igloo by using structure blocks to manually load them from the /data/minecraft/structures/igloo folder in version.jar. To do so, set a structure block to Load mode, enter igloo/structure name, and press [LOAD]. The individual structures are bottom, middle, top.

igloo/top
The above-ground room of the igloo, made of snow blocks.
Golden apples in the igloo chests now have a 100% chance of appearing, where previously they would often not appear – it was moved from the structure file to the loot table.
Golden apples originally would always be found in the central slot when they were found at all; now they can be found in any slot.
In the structure block's data folder for the igloo the names of the parts of the structure igloo_bottom, igloo_middle and igloo_top have been changed to bottom, middle and top.
Due to the empty and water cauldrons being split into different blocks, cauldrons no longer generate in igloos, with water cauldrons taking their place.
Due to the addition of the new zombie villager skins the zombie villager in the basement is now a cleric rather than getting a random profession when cured.

Trivia
In Java Edition, if a number of items in the igloo furnace are smelted, the light generated melts the igloo window, turning the ice into a water source block.[2] If the igloo has a basement, this can reveal the trapdoor leading to it.
A raid happening around an iglooAn igloo with a basement qualifies as a village in Bedrock Edition due to having a villager, a bed, a brewing stand, and a cauldron, with the last 2 blocks counting as job sites. This means a raid can be triggered in an igloo.
An igloo can sometimes generate on a cliff, on a mountain, over a cave, or on a floating island, causing its basement to be exposed.
