Structures Plus
by Kapp
Structures Plus, a NeoForge mod by Kapp for Minecraft 1.21.1, adds custom structures with their own loot tables and custom items.
What it does
Players who explore new terrain find custom structures generated in the world, each one carrying its own loot tables. The author describes the mod as adding ten structures in total, and the set is presented as a broader structure pack rather than a single building. Because the structures are generated during world creation or as the world is explored, a player encounters them without issuing commands or crafting anything first.
Structures Plus is a world generation mod, listed also under adventure, and it requires no other mod to run. It is published for NeoForge only, for 1.21.1, and both the server and every player need it, so it has to be installed on both sides. Its single release, 0.0.1 for 1.21.1, appeared on 2025-12-01 on the beta channel, and the author notes active development. The code is distributed under All rights reserved, so the mod is not open source.
Key features
Custom structures
New structures are generated in the world, adding locations that vanilla terrain does not provide.
Ten structures
The mod includes ten structures, so the set is larger than a single building.
Custom loot tables
Each structure can hold loot defined by its own loot table, so the contents differ from place to place.
Custom items
The mod adds items of its own that appear alongside the structure loot.

Use cases
Adventure maps
Map makers can place the custom structures in an adventure map to give players landmarks and reasons to explore.
Survival worlds
In a survival world, the structures offer loot that players can collect while they travel.
Who it’s for: Players who want more generated structures in a new or existing world, and server owners who run a world where explorers should find loot in new places. Both sides need the mod, so it suits servers that can ask every player to install it.
