Just Another Structure Pack

by flashbulbs

Overworld worlds gain new structures from Just Another Structure Pack, including small ruins and long-lost labyrinths that players can find while exploring.

FabricForgeNeoForgeQuiltServer required, client optionalAll rights reserved1.19 – 26.2

What it does

The mod places new structures across the Overworld, so exploring a world turns up sites that vanilla generation does not produce. Structures are built to fit into existing terrain and to add variety to a world without changing vanilla gameplay. The mod is also distributed as a data pack, so it can be loaded on a server without a loader. Server owners need it on the server; players may add it on the client but do not have to. Files cover 1.19 – 26.2 across Fabric, Forge, NeoForge and Quilt, and the latest file, 2.5+mod for 26.2, was released on 2026-07-21. The code is all rights reserved.

Key features

  1. Overworld structures

    New structures generate throughout the Overworld, adding sites to explore in both new and existing worlds.

  2. Ruins and labyrinths

    Small ruins and long-lost labyrinths are among the structure types, giving exploration rewards beyond vanilla sites.

  3. Data pack option

    The structures are also available as a data pack, for servers that prefer not to install a loader mod.
