Java mod listed for Minecraft 1.17. Downloads from the MC Java Mods app on Android.
⬇ Download on CurseForgeThe author built this one for Minecraft 1.17 on Fabric. On other versions it may install and then do nothing.
World Height Booster
Changes to 1.17's world height code has allowed for modders to increase the maximum build height to 512 blocks. This mod goes farther - the ground now begins at 300 blocks. Dig deeper underground, and build higher into the sky! Minecraft's final frontier has been broken.
This mod requires the Fabric mod loader. A forge port is currently impossible, because 1.16 lacks the necessary internal changes for this mod to work.
