In the vanilla game, the build limit is Y=319. This limit used to be even lower before the Caves & Cliffs update. These build limits exist so that players will not be able to build or place blocks above it. But what if you wanted to build a superstructure that goes beyond the build limit? Bigger World Height Mod is here with this solution. This mod increases the world height to a staggering Y-level of 2031 in all the three dimensions in the game. Now you can build structures that stand thousands of blocks tall. It is important to keep in mind that launching your game after removing this mod from your mods folder will result in anything built above Y=319 to disappear.
