Storage Builds

Storage rooms, sorting systems, item filters, and warehouse designs.

Automatic Item Sorteradvanced

A hopper-based item sorting system that automatically routes items into designated chests. Each filter module sorts one item type using a comparator-based overflow-proof design.

3x6x4035 steps90-120 min
Item Elevatorintermediate

A vertical item transport system using a chain of droppers to move items upward. Essential for connecting underground farms to surface-level storage systems.

3x16x314 steps20-30 min
Large Storage Hallintermediate

A well-organized storage hall with labeled double chests along both walls, item frames for identification, and enough space for 54 double chests (2,916 stacks).

15x6x2520 steps60-90 min
Super Smelterintermediate

A 16-furnace super smelter that processes items 16x faster than a single furnace. Input items and fuel via hoppers, and collect smelted output automatically.

Which container to use

Chest
27 slots, or 54 when two chests form a large chest. A chest will not open with a conductive block on top of it, so keep the space above free or use something like glass.
Barrel
Also 27 slots, and nothing stops it from opening, so barrels can be stacked into walls and floors where chests would stay shut.
Shulker box
27 slots that stay inside when you break the box, so a full box moves as a single item.
Ender chest
Every ender chest in the world, in every dimension, opens the same inventory, and each player has their own.

Large chests add up fast: the storage hall fits 54 of them, and at 54 slots each that is 2,916 stacks.

Moving items without you

A hopper passes an item on and then waits 8 game ticks, so one hopper moves 2.5 items per second. A longer chain is no faster, which is why the super smelter spreads its input over 16 furnaces instead.

Blast furnaces smelt ores and smokers cook food twice as fast as a furnace, but they also burn fuel twice as fast, so you get the same number of items per piece of fuel. A dried kelp block smelts 20 items, and kelp can be farmed.

The item sorter sends each item type to its own chest, and the item elevator lifts items with a column of droppers, handy when a farm sits below your storage.

Reading how full a container is

A comparator behind a container gives a signal based on how full it is, counted in stacks: one item in a chest already gives signal 1, and signal 15 needs all 27 slots full. Items that stack to 16 fill their slot at 16, and a tool or anything else that doesn't stack fills it on its own. A hopper reaches 15 with just 5 full slots, so it reacts to far fewer items than a chest does.

Copper chests and the copper golem

Place a carved pumpkin last on top of a block of copper and you get a copper golem, while the copper block turns into a copper chest. The golem takes up to 16 of the first item it finds in a copper chest and carries it to a nearby chest or trapped chest that is empty or already holds that item. It spends 3 seconds checking each chest, remembers the last 9 it tried, and after 10 chests without room it wanders for 7 seconds before it starts over.

That makes golem sorting slow, but it needs no redstone: give each item type its own chest and the golems fill them. Wax a golem with honeycomb, because an unwaxed one oxidizes over time and ends up as a statue that drops what it was carrying. An axe scrapes a statue back, and once it is unwaxed bare copper again the axe wakes it up.
