Build Below Bedrock
Build Below Bedrock is a Java Edition datapack that expands the usable building area beneath the standard Overworld floor. It keeps terrain generation and the natural bedrock layer at Y minus 64, then opens 64 additional blocks for construction below that level, without reshaping newly generated terrain.
It is designed for creative projects, hidden bases, underground cities, and unusual adventures on a Minecraft server while preserving familiar vanilla generation. Compatible with Minecraft 1.21, 1.21.1, 1.20.5, and 1.20.6, this utility gives builders extra vertical space without the broader changes associated with height expansion packs. At BoxToPlay, we recommend it for servers seeking more freedom beneath the Overworld.
