Extended Build Limit
by StaticLabs
Extended Build Limit raises the vertical building range of a world, extending it past the vanilla limits of Y -64 to Y 320 for players who want more height.
What it does
Installed as a data pack or a loader mod, Extended Build Limit moves the build height beyond the standard vertical bounds, so blocks can be placed and terrain generated well above or below the usual range. The change applies to the world itself, which makes it a server-side choice that clients can run without changes.
The mod is published for Fabric, Forge, NeoForge and Quilt, and as a data pack, with builds covering 1.18 – 26.1.1 across 29 release versions. Snapshot builds are published too. It needs no required dependency, and the license is All rights reserved, so the code is not open source.
Key features
Extended vertical range
Building and terrain generation extend far past the standard Y -64 to Y 320 limits of vanilla worlds.
Data pack installation
The data pack version can be dropped into a world's datapacks folder as a zip file, with no loader needed.
World generation compatibility
The mod works alongside major world-generation mods such as Terralith, Tectonic and Nullscape.

Use cases
Tall builds on a server
Server owners who want skyscrapers, towers or deeper mining space can raise the limit for the whole world.
Vanilla-friendly worlds
Because the mod adds no new gameplay blocks beyond a few safe additions, existing vanilla survival worlds stay largely unchanged.
Who it’s for: Server owners and map makers who want a taller or deeper world than vanilla allows. Players joining such a server need nothing extra, since the server holds the change.
