Datapack Higher Build Limit

Higher Build Limit, build higher with stability

Higher Build Limit is a Minecraft Java Edition datapack that raises the Overworld building ceiling from Y 320 to Y 640. This provides twice as much vertical space for towers, floating cities, megabases, and ambitious creative projects, while the lower limit remains at Y negative 64 to preserve the usual underground range.

Instead of removing the limit entirely, the datapack applies a moderate increase designed to support a more stable Minecraft server, with less risk of lag or instability than extreme height changes. At BoxToPlay, we recommend it to builders who want more vertical freedom without significantly changing familiar gameplay.
