Repurposed Structures takes what vanilla Minecraft already generates and asks what those buildings would look like somewhere else. Villages, mineshafts, strongholds, dungeons, outposts, shipwrecks, pyramids, igloos and wells all gain new biome matched variants, and some ideas go further than a retexture, including a Jungle Fortress, Nether ruins, crimson and warped shipwrecks and an End ruined portal. Much of it began as world generation for an amplified dimension project before being split out for the Overworld.
One design decision shapes everything else: the mod adds no new blocks and no new mobs. That means it can run entirely serverside, and vanilla clients connect without installing anything on their side. It also makes conflicts unlikely, because the structures are added to biomes directly, and it sits comfortably next to other structure mods, with both sets of buildings continuing to spawn.
Since the structures moved into datapack form, almost everything is adjustable without touching code. Spawn rates can be raised, lowered or switched off entirely, mineshaft generation height and village size can be tuned, loot tables and mob spawners can be overridden, and the advancements can be disabled if the notifications get tiring. There is also a pool additions system that merges new building pieces into existing jigsaw pools from every datapack at once, so several packs can add houses to the same village without overwriting one another.
A regular config file handles the rest, including whether loot from other mods gets pulled into these chests, which is on by default and switched off with a single option. One quiet extra is worth hunting for: rare banners hidden in chests that only show up while you carry the Luck effect, which vanilla cannot grant on its own. This is the NeoForge build for Minecraft 1.21.1 at 7.74 MB, and it is explicitly cleared for use in modpacks.
