This DataPack brings back the brick house from a mod called Rogue Like Dungeons, now in your vanilla world out in the Plains with a chest that comes with randomized dungeon loot, this is my first ever datapack and thanks to this pretty nifty template i worked off of it worked quite well, although if you do use it, i recommend using https://misode.github.io/upgrader/ if you use his template.
Credit goes too him for the use of his template Titruc
and of course https://www.curseforge.com/minecraft/mc-mods/roguelike-dungeons
