Tutorials/Shelters

Core Rooms
There are several things every Minecraft shelter should have.


 * Craft Room
 * This is the single most important room and should be the first one built. A craft room should include a crafting table, at least one furnace, and at least one chest containing important and rare crafting materials that you don't want to accidentally lose while mining.


 * Mudroom
 * This room should have supplies so you can quickly get them and leave without needing to go to the other side of your shelter to get what you need. This should be well-defended as it's generally a main entrance to your base.


 * Furnace-room
 * This is important if you are a big miner and every miner should have one. This also enables quick production of several stacks of charcoal, smooth stone, and glass.  Make a big room and line the walls with furnaces; possibly keeping a chest of fuel inside as well. The benefit of having multiple furnaces is to help speed up smelting since each furnace is able to run independently.


 * Storeroom
 * A room full of chests for storing all of the dirt, cobblestone and other less-valuable materials that accumulates in your inventory while mining. This should be built once your main craft room starts to overflow.


 * Entrance to your Mine
 * It's generally a good idea to put the entrance to your mine inside your shelter. If you return at night, you won't have to make a mad dash to your house. It's probably a good idea to make sure your mine is well lit, or invent a decent way you can enter your shelter from the mine or vice versa without mobs being able to do the same.


 * Bedroom
 * Since Beta 1.4, sleeping in a bed resets your spawn point to the last bed you slept in. Put beds in all bases to easily transfer primary bases. This room often shares purpose with another room. Also, sleeping in a bed at night causes time to pass quickly. If you want to avoid the aggressive mobs that come out at night a bed can greatly improve productivity. In earlier versions of minecraft, if you placed your bed next to the wall then aggressive mobs would have spawn in your house to wake you up if you place your bed less than 2 blocks away from the wall. To fix the old bug, you would have added extra layers to your wall or placed your bed at least 2 blocks away from ALL walls, or just place it on a 2nd floor.


 * Bunker
 * Sometimes called a panic room, it is a small room made of strong materials (obsidian for example) with a metal door with the open/close system inside the room. It has to have a bed, a crafting table, a furnace and also a chest with the basic materials. It has to have a high luminosity to avoid monster spawn inside.


 * Brewery (post-Nether)
 * Once you've been to the Nether and gathered some Blaze Rods, you can create a Brewery, which is simply a room with a Brewing Stand and a Cauldron. It is good to be able to brew some potions to prepare yourself for leaving your base. Include a chest with some potion ingredients.


 * Enchantment Room (after getting Diamonds)
 * This room is a good use for your Sugarcane, and it lets you enchant your items. See Enchanting for help on design. To make it better you could add bookcases near it to get you higher level enchantments.

Expansions
These projects, while not entirely mandatory, make your base more useful and interesting.


 * Redstone Lab
 * A laboratory is a large, clear, secure area where you can safely test designs without distractions. When building large projects with complicated parts, it can save you effort if you test the ideas first.


 * Balcony
 * Place your balcony where it is facing a nice view!


 * Cobblestone Generator
 * A cobblestone generator provides a safe and convenient way to gather cobblestone. They typically involve mixing water and lava.


 * Scout Tower
 * A cheap and safe way to survey the land.


 * Beacon/Lighthouse
 * A tall tower with some sort of light source on the top means that you can see your base from a long distance away. Handy if you go exploring a lot, your spawn point is a long way from your base, or you have not made a bed yet.


 * Kennel
 * If you have tamed a lot of wolves, a kennel is a good place to keep them in. A simple shed-like structure will suffice, but be sure to keep it well lit, for the wolves' safety.


 * Well
 * A renewable water source is useful for a variety of projects. Put water in a 1x3 ditch and you can take water repeatedly from the center!  For a more aesthetically pleasing pool, a 2x2x1 well works as well, and you can take water from any of the squares. You could even make the stream run downwards several stories in your building, and use it as an elevator.


 * Wheat Farm/Greenhouse
 * A renewable source of food from the safety of your base is incredibly useful. If your base is underground or has an expansion underground it is very recommendable to make an underground farm to avoid possible animal tampering or creepers blowing up part of your farm. See Farming.


 * Melon or Pumpkin Farm
 * A constant food source in your base that keeps your hunger bar up and souls for Snow Golems.


 * Tree Farm
 * Producing wood in your own base can eliminate a major reason for venturing in the dangerous outside. Make sure your farming room has a torch next to each sapling and has enough space upwards. A chest with axes, saplings, and spare wood can be helpful as well.  See Tree Farming.


 * Mushroom Farm
 * A big room with flat floor. You can light your farm by torches or glowstone, placed on ceiling, to prevent mobs from appearing. Just make sure that there no places on floor where light level is greater than 12. More about it can be found on Mushroom Farming page. Alternatively, find a small cave or make one, put some mushrooms inside and completely seal it off without torches and check on it/clean it out. Also provides the drops from hostile mobs.


 * Sugarcane and Cactus Farms
 * Easier to manage but somewhat less useful than the above two projects, farming reeds and cactus underground requires little effort. A cactus farm requires sand to grow, and reeds need to be properly irrigated, with water within one block of it. If you don't want to spend tons of time harvesting your cactus, place a three-block-tall pillar next to where you want your cactus. Removing the bottom block allows you to place the cactus and when it grows, the two above blocks make the cactus automatically break off.


 * Chicken Coop
 * Farming eggs is possible, though time-consuming, by locking yourself in a small room and throwing enough eggs to spawn several chickens. Place water so that any eggs that are laid float toward you, and then walk away from your computer for at least a couple hours.  At about one hour the chickens should have produced enough eggs for you to break even; waiting three or more hours will reliably give you a good number of eggs.
 * The simple "small room" method is good for starters, but it's possible to create fancy multi-level structures that drop eggs to the player as well. Hint:  Chickens will always stay above water suspended by trapdoors, signs and ladders, but the eggs they lay will sink down. Keep in mind that, though ladders are a more efficient use of wood to hold up the water, the eggs that chickens lay might get stuck on the ladder. This may also happen when using trapdoors. Using signs instead remove this potential problem.


 * Indoor animal farm
 * Light up a large area with a grass floor and you can gather wool, leather, pork, beef and, Raw Chicken safely.


 * Incinerator
 * A room with lava, for disposing of unwanted materials. A good way to do this is to create a two block high corridor with lava at the end, and a slab block just before the lava. This results in you being able to walk up to your incinerator but not into it, eliminating fear of death. Be careful with lava around flammable materials. You may replace the lava with a cactus block, or burning netherrack.


 * Obsidian Farm
 * Natural obsidian is dangerous to mine, let alone finding it. Make a long, narrow, enclosed pit to store lava in. The easiest way to get lava is in The Nether, so you may want a portal in this room as well.


 * Minecart Hub
 * If you have active mines scattered over the place and use Minecarts to haul your stuff back to your base, dig out a universal stopping point under your base.


 * Indoor fishing pond
 * This is very easy to make, and can be very useful, especially if you don't have a wheat farm yet. Just make a hole long enough to cast your fishing rod, around 8 blocks long and four blocks deep, and fill it with water.


 * Portal Room
 * Once you have at least 14 obsidian, either from mining it in a cavern or obtaining it though obsidian farming you can build a portal. Once built, activate it with a flint and steel, and you can travel to the nether. This can be used for fast travel and for getting lava, netherrack, Soul Sand and glowstone. Beware of ghasts. If you have no diamond pick axe and cannot mine obsidian, you can create a portal by placing 10 lava source blocks in the proper places and freezing them into obsidian by pouring water next to them. Water cannot be placed in the nether, and as such you must bring 10 units of obsidian with you if you wish to build an alternate exit portal. If you do not wish to hear the sound of your portal, simply put it out by using Flint and Steel on it a second time.


 * Storeroom System
 * After a few days worth of play time, you will start to run out of space. Continue making more places to store your dirt and stone, or better yet, dig two blocks under the original chest and place the new chest there (you need space for it to be able to open it). You can also use signs to mark your chests. A handy place for it is next to your craft/furnace room, or on your way up or down your mine.


 * Mob Grinder
 * A safe, renewable source of gunpowder, arrows, rotten flesh and bones. Which makes exploring much safer and can provide the means for large amounts of explosives.


 * Music Room
 * A room filled with note blocks to enjoy melodies made with redstone repeaters or without.


 * Pig Farm
 * If you are playing on a multiplayer server and you are an admin, you can use the give command to give yourself pig spawners. (/give playername 52 1). One of the simplest ways of make a pig farm is placing netherack in the ground next to the spawner and lighting it. When a pig walkes into it, it catches on fire, and when it dies it gives you Cooked Porkchop.


 * Library
 * Not only is it a great use for any excess sugarcane, a library can also add a bit of class to your home. Can also double as an enchantment room.


 * Minecart Chest System
 * After a lot of days in Minecraft, you will soon have the ability to automate everything (farms, doors, etc). The most useful automation you can make is a Minecraft Chest System. You can simply craft Minecarts with chests, Booster rails, and some rails, you can make a system to send your ores up your mine to your base, and have a minecart with more tools come back to you.


 * Gravel-to-Flint room
 * Once you have many stacks of gravel, it can be useful to convert most (leave some for mining) of your gravel into flint. This is just a big empty room (a 4X4X4 space holds a stack of blocks), which you fill with gravel, before destroying the gravel, getting some flint in the process. It is most efficient to do this 10 - 15 times for every 20 stacks, though about 5 for 10 stacks, and 30 for 50 or so stacks. This room may include a chest with shovels, as well as ingredients and a crafting table for quick production of arrows, and flint and steel.


 * Lookout tower
 * If you always get blown up by creepers when you go out your door, you should think of having this. Just make a very high platform with ladders or stairs to it. Then on your platform put fences on the perimeter. Very handy.

build a mid. to large building then inside put two passive mobs with the same kind like two pig or two cows then breed them you can also put trees inside so animals feel more comfort or build a man-made forest and then observe the family.
 * Animal observation building

Build a medium-size, tall building with 1x2 openings at the base. Place 2 layers of snow near the top, so when it's night you can place the pumpkins on and have some help fighting (or at least holding back) mobs.
 * Snow golem building

Defense
These additions make your base safer and provide a certain amount of entertainment.


 * Fallout Shelter
 * Build a basic shelter out of obsidian. This will be a place where you can retreat to in case a bunch of Creepers are out to blow you up.


 * Snowmen Defenders
 * Since snowmen shoot Mobs back, consider adding holes in the sides of your walls with little rooms attached to each hole. Then build Snow Golems behind each of the holes. You should be placing the pumpkin head 1 above the hole, because when the snowman is formed, it is only 2 blocks high.


 * Overhang
 * Since Spiders can climb walls, a base needs to have either a ceiling or an overhang along the outside walls to be safe. The walls must be at least four blocks high (since spiders can jump up to three blocks high). Of course, a closed roof with a lava pond on top is also nice...


 * Perimeter
 * Adding torches around your base can reduce the amount of monsters that spawn nearby, so add some light to your lawn! You can also use fences, cacti, and burning netherrack to keep enemies out. Just remember that spiders can jump your fences.


 * Floodgate
 * Using a fairly simple redstone circuit connected to a lever at one end, and one or more pistons at the other end, you'll be able to build some simple floodgates. If you extend the pistons first, and then place water, or even lava behind it, you can get rid of or even kill any mob passing by by pulling the lever and letting the water or lava flow! For a quick morning mob clean-up and a strong sense of catharsis, you can place lava floodgates surrounding your entire shelter, facing out.  One throw of the lever reduces the surrounding landscape to a barren, hellish wasteland!  Not to be used in wooded areas.
 * (Note: this tactic is borrowed from sister game Dwarf Fortress, and is colloquially referred to as "pulling a Boatmurdered".)


 * Moat
 * The simplest of these is a "dry moat" or trench, a couple layers deep so that skeletons and zombies can't get across. This can provide you with a reasonably safe area that is outside.  This can be filled with water to push the enemies to a mob grinder, or simply filled with lava which has more dramatic and obvious effects. Please note: It might not be a good idea to use lava when having a shelter built out flammable blocks such as wood, wool or wooden planks. Tower shelters would do well to have a three-block deep water moat to break the player's fall so they can safely fall to the bottom.


 * Lake
 * If a moat does not feel sufficient, build a lake around your base, preferably several levels below the entry level and with a bridge to allow easy access back and forth. Again, it can be water, or, if you want a dramatic flair, use lava. Remember to protect the bridge well, though, and be sure you are protected from within the island in case you miss a spawner. Making a drawbridge out of trapdoors is a fun alternitive to the actual bridge.


 * Archery Tower
 * If you have a plentiful supply of arrows, building a small tower to pick off nearby monsters can be fun and provide useful resources such as gunpowder.


 * Dispenser Turret
 * Put a dispenser with some arrows at your desired location (preferably next to a door) and a Stone Button/Lever/Pressure Plate attached to it. This is handy if mobs want to pay you a visit.


 * Traps
 * If you're not satisfied with moats or a perimeter fence, consider adding a trap or two. If you're up to a challenge (and on a SMP server), you could even make an entire trap, designed to look like a base! Dark rooms with no way out for mob spawning, entire mazes made of glass, and traps using pistons and lava. The possibilities are endless.


 * Wall
 * Build a large wall, light the area inside and you can live "hostile free".


 * Drawbridge
 * Using trapdoors, some redstone, and switches, a simple drawbridge can be made. Dig a moat around your base and make sure it is too long to jump across. Now, make short walls next to your entrance. Depending on whether you have a single door or double door, you will have to use one row or two rows of trapdoors respectively. Run redstone next to the trapdoors and connect them to switches inside your base, then cover up the redstone walls. This prevents mobs from getting close to your door while you are inside your base, but the bridge will have to be left open while outside your base, otherwise you'll have to find another way back in. Alternatively, you can make a XOR gate and place another switch outside your house to trigger the drawbridge from anywhere.


 * Sticky Piston Drawbridge
 * It is possible to make a drawbridge using sticky pistons that is very difficult for a mob to cross. This draw bridge also involves the use of a moat or lake. A knowledge of redstone logic gates and how power is supplied to blocks is needed as this mechanism uses multiple redstone repeaters, NOT Gates and a T-Flip Flop. Using the T-Flip Flop one can wire the drawbridge so that it becomes accessible or inaccessible with the touch of a button from either side of the bridge. When the player(s) wants to cross the button is pressed causing both ends of the drawbridge and the center to be even allowing the player(s) to cross. When activated to keep mobs out both ends of the drawbridge are raised 1 block higher than the water level making it impossible to jump from the water to dry land and the center blocks are lowered 1 below the water level causing the center area to flood. Assuming both ares are properly lighted and secured this creates an impassable entrance to one's base.


 * Secure Waterfront
 * Because zombies and skeletons can survive sunlight in water and hostile mobs can swim, if you have a base on the coast it's a good idea to make sure it isn't vulnerable to mob attack. Building canals, lighting nearby islands, and building walls on areas of water you don't use can stop very rare, but still as deadly, attacks from the sea.


 * Blast shield
 * About 3 or 4 layers of some cheap material (e.g. dirt) placed on the house will make it ugly, but it prevents creepers from doing any damage to your house. Instead, you could use obsidian too.


 * Self-Rebuilding Wall
 * It's possible to apply the idea of a cobblestone generator and use pistons to make it automatically rebuild damaged walls. Generally more effort than it's worth, but very neat-looking.


 * Land Mines
 * If you like to blow up stuff, you might like this. All you need is a lot of pressure plates (wood) and TNT. Once you found your spot dig two blocks down. Then place the TNT then another block, then the place the pressure plate. You can have a big mine field but more effort than its worth.


 * TNT Cannon
 * TNT cannons are a good destructive way to take out mobs. Make a TNT cannon and have a chest full of TNT. For more detail go to TNT Cannons.

Other Ideas
There are infinite possibilities in Minecraft. These ideas are not especially functional but can be fun to make and have.


 * Add underground floors to your shelter.
 * Using this gives you a chance to find resources, and, in the case of invasion by mobs, it will always provide a safer spot. Underground floors are also useful for making mob grinders or animal farms.


 * Add above-ground floors to your shelter.
 * It is normally advised to do this after building underground floors if you have a ton of resources (after mining the basement out). This could even give you a chance to "snipe" some creepers and spiders in the morning.


 * Remake it out of a different material.
 * Install luxurious violet carpeting for the bedroom. Give your craft room a nice glass roof.  Rebuild the armory out of obsidian.  Redo your outer walls in smooth stone. Add a second story to your library.


 * Make another base in a new location.
 * Having more than one base helps if you need to travel farther to get resources. A base next to your spawn point is helpful if you built your main base somewhere else. A base in a desert can provide sand, and a base in a tundra can provide snow.  A base hovering in the sky can provide entertainment, especially if mobs spawn on the edge of it.


 * An emergency kit.
 * In case you need to quickly gear up and run back to get dropped gear. Perhaps a sword, cake or a stack of porkchops, a stack of torches, and maybe some TNT? A more advanced kit can be made from dispensers that give you items at the click of a button, although arrows and torches will still have to be accessed from a chest or two.


 * Add an escape tunnel.
 * You never know, that creeper might one day get you. Bonus points if the tunnel leads to a secondary base.


 * Lava lamp
 * Simply make a hollow space out of glass and fill it with lava. An efficient method is to run a vertical column through many floors powered by a single lava block at the top. You can also make one of these high above your base to mark it from afar. If your house is made out of flammable blocks, this isn't recommended.


 * Quarry
 * A Quarry yields very large amounts of materials such as raw cobblestone and dirt to make your buildings, and coal and iron to make tools and torches. It can require several days of gameplay to finish building.


 * Mining shaft sunroof
 * Making a sunroof that points directly down your mining shaft has its advantages: you will be able to tell the time of day more easily, and burn mobs like the zombie and skeleton.


 * Lava beacon
 * Make a large pillar of stone or any nonflammable material and pour a lava bucket on it. It helps when you are a long way from home.


 * Glass floors
 * No mobs can spawn on glass floors, making for a handy alternative to a well-lit shelter.


 * Lava floors
 * Similar to having a lava lamp, have a 1 block high space below all glass blocks on the floor and pour lava there. This will keep your shelter visible and provide a fancy, creepy feel.


 * Doorbell
 * Mobs (and players!) entering your house without you knowing is a pain, that's why you need a doorbell.
 * Requirements: 1 Redstone, 10 wooden planks.
 * First craft 2 planks into a wooden pressure plate, Now take your wood and redstone and craft a note block, Place the pressure plate on your entrance and the noteblock beside it, When a mob or player steps upon the plate the note block will play a sound, You can make this more sophisticated making chimes or even a whole song that play upon entering.

If you have multiple entrances to your base, place different blocks under each note block to make sure that if a creeper comes to your west entrance, you don't get blown up when you head to the east entrance. Just be sure to test the sound produced to make the doorbells distinct.
 * Blinker Beacon
 * A more technical variation on the Lighthouse.
 * Requirements: 5 redstone, 4 sticks , 5 cobblestone (dependent upon height)
 * Place one block and cover each side with a redstone torch, next place redstone on top of this block, finally place a block above each torch.
 * This will cause a random off/on effect making the redstone torches blink, Construct this at higher altitudes so no trees or cliffs can keep it out of your sight.
 * When leaving the game on single player the redstone torches will turn off and no longer blink, upon relogging this may require some maintenance.
 * You may also use a minecart rail system, which can be made so-
 * You put down rails in a square(4 rails on every side), then put down a booster and detector rail, power the booster, and connect the detector rail to the torches you want to blink with redstone. Place a minecart on the booster and it will loop forever.
 * This can be used to blink multiple torches with the same system, and does not require maintenance.
 * You may connect more detector rails for faster blinking speed.


 * Outpost
 * Make a small room somewhere away from your base. You can include a bed, a cake on a table (for food), a crafting table, a furnace and a chest. This is helpful as a simple second shelter, and the cake is a useful source for restoring the hungerbar if it gets low.


 * Dock
 * If you find yourself using boats in a general area often, making a dock or two is a good idea. They can help prevent your boats from drifting off into the ocean, or slamming into a wall when you exit, thus breaking the boat. Dispensers can also be placed here and filled with boats for convenience. Chests filled with boats are a good idea too. There are several ways to make useful docks.


 * Placing half-blocks in the water. When a boat moves on top, it will slow down and stop immediately. Half blocks are shorter, so your boat will not collide with it and break.
 * Warning: it is recommended to only use this method on Peaceful difficulty and to land on the half blocks at a low speed, instant death is possible when landing on half blocks at max speed.


 * A closed dock. One type of dock is by making a small area (2x3 or larger) that is filled with water. You can place doors in the water, allowing you to ensure your boat will not drift off. Soul Sand is a suggested building material, as it will prevent all of the impact damage from colliding with a wall made out of it.


 * Water currents. By using a bucket to remove the top layer in 2+ deep water, you will create a + shaped water current flowing towards the center. You can use this to hold boats, while still being able to escape somewhat easily. This design does not always prevent the boats from moving if you or a mob bumps into it, but will help prevent it from drifting away


 * Piston elevator
 * If your base happens to be atop a large mountain or if you have a deep mine below you base then a elevator may be a good idea. Elevators drammatically cut down the time that it takes to travel vertically.


 * Mailbox
 * Simply put a chest on top of a fence post. This is only useful in a multiplayer server, because creepers or other mobs wont give you mail.


 * Fridge
 * Create a fridge by placing a dispenser on the ground, a block on it and a button on the side of the block to quickly get something to eat when you're starved (and Add a door infront of the dispenser if you have enough iron).


 * Miniature zen garden
 * Either above the surface or underground, create decorative minimalistic works of art using water currents, plants/crops/flowers, sand, clever use of fenceposts, signs, torches, etc.

Tutoriels/Choses à faire dans votre abri Tutorials/List of things to do to your shelter/ch


 * Fountain
 * These are the fountains you see in strongholds. All you need is 22 cobble stone and a bucket of water. Make a 5 by 5 square with the nine in the middle taken out so the water won't spill. Then make a 4 block high pillar in the middle and place the water there. Very attracting.


 * Piston Doors
 * These are very cool looking. Have these any where in you house, library, craft room, furnace room, you name it. All you need in red stone, sticky pistons, and levers.


 * Tunnel to a Stronghold
 * After you found a stronghold make a tunnel to it. Easy way to get to The End.


 * Add a carpet
 * You can spice up your base by adding a carpet made out of colored wool. Make sure that fire and lava aren't less than 2 blocks from the carpet otherwise, well, your carpet will go up in flames!


 * Rollercoaster
 * If you have enough resources, build a rollercoaster out of rails. This is a decent way to keep occupied while you have nothing else to do in the vast world of Minecraft.


 * Sky Base
 * Create a base floating in the sky with no bridges or stairs connecting it to land. Can be accomplished with waterfalls, piston elevators, and nether portals.


 * Battle Arena
 * The first thing you must do is find a mob spawner. Then seal off any extra entrances and place a door at the last remaining one. Finally make a lobby room with chests full of equipment and food. Now you can fight that specific mob whether for exp. or drops for as long as you want!


 * Spleef Arena
 * Great way to have some fun with your friends on multiplayer. You should make a Snow Golem room to be able to collect snow balls easy to craft into snow blocks. You can bet on games, build a score board and have stands for people to watch. Stands are best made of wooden or stone stairs because they most look like regular seats and they are the cheapist. You can also make it so the looser faces a little more punishment and humiliation by making it so if someone falls they will either get burned or death by lava. This makes it a little more fun and plesurable to watch your opponit burn.


 * Railway
 * make a long tunnel to fit 1 to any amount of minecarts then use minecarts with furnaces to propell the 'train'. also add emerngy chests to the side of the track and fill them with coal to power your minecart so you don't get stranded. this is fun for SMP and single-player and you can go across the land quickly.
 * TOP TIPS don't make your railway aboveground. you will constantly be attacked by creepers.Make stations for your fave landmarks(big mountain,my house.ect..)charge other players to ride on it.a perfect may to get coal.

Make a DELUXE version for long journeys.get waiters to bring other players food when there hungry.(charge dimonds or obsidian).make windows in the tunnel. on EXTRA long journeys put beds in the stations.


 * Post Office
 * Hire players in SMP and make a post office and service.Players go in the post office and ask the mail men to dilver a block to a house or cave. charge extra for long journeys and dangerous jobs.


 * Army
 * Make an army. players can pay the army to protect their homes for food and weapons.Perfect for SMP.Charge based on location and how long.


 * National Park
 * corner off a HUGE area of land with big mountains and amazing caves put in information signs and charge people to visit. make some camp-sites to house players exploring. in the camp-sites put chests with food or weapons. players must give back items they used.


 * Bin
 * Make a Bin to dispose of unwanted items. Make a 2x2 hole with water in. 3 Blocks deep. Put signs in all 4 corners so that the water will float on top. Then put flowing water underneath with lava at the end of the flow. Be cafeful not to set things on fire with the lava.


 * Bank
 * Make a bank to store items. Only useful in Multiplayer. People can pay in Gold/Diamond to store the valuable items that they may own. The Vault could be lined with lava or bedrock to make it super secure.
