What is an Underground Base in Minecraft?

Underground bases in Minecraft are built within the planet’s crust. This means that Minecraft players must mine to create passages in their underground base, unlike some innovative, fully tunneled spaces such as the South American Cu Chi Tunnels in Vietnam which start anywhere from 3 to 67 feet below the surface. Minecraft underground bases are a key way to gather resources and have unique structures without disrupting the pristine natural beauty of your ground.

Why Build an Underground Base in Minecraft?

There are numerous reasons for building an underground base in Minecraft. Some reasons to do so include:

  1. Geothermal power generation
  2. Living underground is one way to avoid the dangers of Nether/End dimensions
  3. Space saving if playing on an island or very small continent map
  4. Resource hiding (e.g. loot from a previous fortress raid)
  5. Protect from more advanced players/persistent mob attack which is protected by obsidian

Here is a video by Jerica Tack on why you should make an underground base in Minecraft.

Protection from Mobs

  • Underground base with mob-proofing hazards. Basic underground base projects provide no additional protection against hostile mobs. Access for such entities can be granted by poorly placed chests or any furnaces with simple indoor exits which can damage the stable signal plant.
  • Underground Reinforced Base with Security Measures. Recently, an underground base in junction city built some security measures in the form of moat water hazards to allow for safe entry on the land floor.
  • Underground Base with Haste effects. The new waterlogged blocks can provide stability higher resistance against a blast and a temporary speed boost if necessary, but are primarily for aesthetic purposes.
  • Harvest Birch or Acacia Saplings. And with some gentle force of water during a rainy day plants on the open vial can drop out safer mob flanking routes.
  • Completely Underground Base Constructed from Scratch. A main base will endure the construction of defence-related structures, which is why tunnels are best used to connect to mines or existing systems.
  • Scavenger Hunt for Good Underground Locations. Required resources can be a few good accessible diamond ores (though not too many should be exposed to reduce the surface’s total worth), rare fascinating biomes above the base for aesthetic reasons and challenging mobs such as Striders and Endermen for the biodiversity of hostiles above the base.
  • Security & Aesthetic defenses should be accounted for when determining an underground base site.

Concealment and Surprise

When building an underground minecraft base, one of the best methods of keeping yourself hidden is to select a terrain type which is easily passable and easily plant trees or other vegetation which serves to block view and access. Peaks such as the Savannah Plateau, Glacier, Jungle Peak, etc. are mountainous regions that offer good concealment because they can be easily altered to make the entrance to your base invisible, are covered with snow which is difficult to walk through and can be disruptive for someone trying to spot your base, and contain thick forests which themselves make it difficult to spot the entrance to underground bases.

Aesthetics and Creativity

Underground bases in Minecraft are limited only by a player’s preferences and imagination, and creativity is encouraged for design. Traditional underground bases built in survival mode with safety, comfort, storage, farms, and maximum efficiency in mind can still be castle-like if you make them spacious with multi-levels and large common rooms.

In creative mode, unique building materials and blocks like stained glass and high-value ore blocks can be incorporated into designs.

Materials Needed for Building an Underground Base in Minecraft

The materials needed to build an underground base in Minecraft are the same materials needed to build bases on the surface. The most common materials include various types of solid blocks and self-illuminating blocks, glowing lichen, jack-o-lanterns or sea pickles. The self-illuminating blocks and items can be used collectively to create the underground base’s lighting system. Enchanted armor and tools such as a pickaxe that have lighting enchantments can also be incorporated to assist in seeing in dark corners.

These tables show different materials that can be used in v0latag’s modern underground base, and indicate their minecraft source, block type, and light level. The roof of some types of underground bases have no room for lapis lazuli should shelves be added, but this density of lighting sources is high even for safety reasons. The total block requirements with and without iron from the floor of a build level in the underground base are 90.53 solid blocks (88.38 meters) and minimum build area for double doors for the entrance is 249.46 solid blocks (230.94 meters).


The Pickaxe is a tool used to mine stone-related blocks (including ores and its blocks). Mining these blocks can be a slow process if using fists, on the other hand simply using hands would make mining these blocks impossible. As the pickaxe is the only type of tool that can get resources in underground settings by breaking stones, so the pickaxe is an essential component of any underground plan.


Darkness within underground bases poses a problem regarding vision. To increase visibility within below-ground rooms and passages, a player can craft torches. This is a simple enough tool which requires little by way of resources: specifically, nothing more than a stick of wood and one piece of coal. Use this recipe to make torches:

  1. Step 1: Acquire sticks by placing one piece of wood in the crafting bench.
  2. Step 2: Before placing the sticks in the crafting bench (they can be randomly placed anywhere) place the piece of coal there too. This produces four torches.

To place torches on the surface of the under base operational area, the player must attach the torch to the side of a block.

Right-clicking on the side of a block will place a torch if the Forward torch placement is deactivated in the Tab menu.

To do this hover over the targeting options on the Crafting Bench, press and hold F3, and then press F3+T. Repeat this process to re-enable this option if needed.

Building Blocks (Stone, Wood, etc.)

Your building blocks for a Minecraft underground base can vary greatly based on your world’s biomes and the design type you choose. There are bound to be wooden options, some light, some dark, so choose the wooden blocks that most appeal to you on a case-by-case basis.

However, regardless of biome-specific cheap alternatives to stone material, players building underground in Minecraft should be heavily using stone mux. A mushroom farm might be the best example – mushrooms will grow on stone or dirt, but 40 stone mux will drop mushrooms as you progress through your other underground builds.

Doors and Trapdoors

For your underground home in Minecraft, place gates, doors, and trapdoors at both the top side and underground entrances which provide similar security to signs that prevent zombie overgrowth and hostile mob invasions. Zombies, spiders, and other potentially lethal mobs will eventually be able to bypass even the cleverest of locked door systems, but locked doors and doors requiring buttons to be opened can provide some usability even after a siege has temporarily been breached.

Step-by-Step Guide for Building an Underground Base in Minecraft

A full step-by-step guide includes the following steps for building an underground Minecraft base: gather resources, decide the purpose, build the base entrance, dig out the volume of the underground section first, figure out lighting and security, construct doorways and hallways, carve out extra rooms, decorate and organize, figure out ventilation, resources, and growth, and complete large room projects.

Choose a Location

Choose a location where you have a hill or mountain to prevent drilling down excessively. This way, you may have easily accessible storage ore without the inconvenience of going more than a few dozen meters below the ground. Remember that having iron or some other easily harvested resource like coal will be invaluable in the early game, allowing you to create all-important stone tools and mine shafts through which you can easily gather underground biomes. Also, avoid transient sources of lava and water as they limit available space and put the whole base at risk. Remember to find a fertile location that is already conveniently close to transportation networks.

Digging the Entrance

The next step in how to build an underground base is to lay out and start digging the entrance. This entrance will be the main vertical axis that connects your surface life in the overworld with the underground base. You have already selected the optimal location for the entrance in the early planning phase by determining the preferred base site. The entrance serves as the physical and visual gateway between the over and underground and its architecture can thus become an important part of your overall base design.

It is important to remember to secure the entrance against unwanted guests, both mobs and other players. The simplest way to do this is to have it covered by a trapdoor but there is a wide array of strategies for entrance security that one can design into their custom style entrance both visible and hidden. These range from turrets, dispensing lava to block invaders, traps with hidden doors that function as a teleporter to other locations, and block and redstone locked security systems.

Creating Rooms and Hallways

After selecting the best location for your underground base and determining its dimensions, you can start laying out the main rooms and connecting hallways. These rooms and hallways should prioritize functional and aesthetic considerations depending on their importance.

It is fairly easy to remove blocks in Minecraft and try new configurations, so it is a good idea to experiment with several layouts when starting out and then refine it down to just a few. This was the approach taken in the early stages of construction for the Minecraft project shown in Figure 5.

Make sure you are considering your function by having larger central hallways and smaller storage or mine hallways. Try lower ceilings to define certain areas and larger vaulted or decorated ceilings for communal areas.

Adding Storage and Furnace Rooms

Storage and furnace rooms are important for any underground base, as they allow the player to have storage nearby and are close enough to the cooking station to minimize the amount of time the player must spend away from their main work area. Storage and furnace areas can be included in the landscape or simply in a hollowed out underground extension of the main rooms. Furnace complexes may be made adjacent to lava pools, as furnaces can be powered by buckets of lava fuel, and are important for refining iron.

The Southeastern Los Angles College entrance to the underground river has a number of rock walls. A main pathway leads to a large storage room filled with double chests on top of stone pillar supports. The stone, metal, and wood rectangular pillars have a number of ring accents and ceiling chains hanging from metal and stone hooks. The pillar pattern provides an inherent order where tools and other objects can be cumulatively stored.

Decorating and Securing the Base

For decorating, Tips for Designing an Aesthetic Base include hanging chains from the ceiling and putting plants such as Sea Pickles on the floor. A variety of lights at 7 to 11 block intervals in a grid is important for evenly lighting floors and ceilings. These are the fundamental requirements for keeping the base secure. Plant Iron Golems near the entrance to the base. Use Glowstone as floors and torches to create confined spaces not accessible or navigable for mobs.

Tips for Building an Effective and Efficient Underground Base

Here are three simplified steps that anyone can follow to build an effective and efficient underground base:

  1. Location Selection in Minecraft: When selecting an underground base location in Minecraft, find a biome or area that is conducive to your needs.
  2. Resource Collection Efficiency in Minecraft: You can maximize efficiency in the early and late game by selecting efficient mining patterns and keeping your resource areas close to connect with rails or ice paths.
  3. Time Management in Minecraft: Have a plan for your build that you are comfortable with and build each day by breaking ground and creating an initial outline.

Use Water Elevators for Quick Access

Fans of Minecraft Youtube personality Ilmango this tip familiar because he has found them to be among the quickest forms of vertical transportation in Minecraft. When you build your underground base, you’ll likely have more than one floor with different areas you plan to use frequently. Consider using water elevators because they can quickly transport you from one floor to another. They are also less claustrophobic and more likely to be perceived favorably by people who have to use them who would otherwise not enjoy claustrophobic forms of vertical transportation.

This is important to keep in mind because if you do not give your workers transport around your base that they are favorably inclined towards, they may become less productive. Practical Science has a good tutorial of how to build water elevators for those unfamiliar with them. Tomax-Akios illustrates a stylish underground base design using glass. The use of glass for a clear view on outside scenery and well-lit chambers is part of why they are so stylish. Using Redstone-powered Pistons is another thing to potentially include in your underground base. It can prevent other players from being able to follow you or flood your facility for you, which would make it difficult for them to explore your base further and make it easy for you to sustain and control your base.

Last warning is there is no consistency or guarantee of results with random Redstone contraptions, that is why they are very unreliable in this version.

Utilize Redstone for Traps and Security Measures

To prevent intruders in your underground base in Minecraft, you can use different traps which are more safely designed with the help of Redstone. Redstone is a material in Minecraft which is used for wiring and can be used as tools and weapons against players like dispensers filled with lava or other harmful substances to injure attackers. Redstone can be used with pistons to effectively create hidden doors and secret rooms which hide entrances and materials, giving you more security.

It can also be used to open and close hidden traps which can dispose of enemies. An important consideration when using redstone in defense mechanisms is to prevent the entrance from being sabotaged by enemies. It is a good idea to keep your redstone in mines/cart pushers.

Incorporate Natural Features for Aesthetics

Your underground base is modular, with each module specialized for specific functions. As such, storage rooms should be kept separate from living spaces, power centers, or even workspace. By tagging specific shortcuts throughout your base and setting warp points, navigating your multi-functional base is much easier. Just drop a few buttons and signs for your Quartz and Rail system and you’re on your way.

Pockets at the top of the cavern you are building in can dramatically speed up the excavation process. Ancient and incredibly valuable ores are much more likely to be found on the lower levels of the cavern, so try to create a system that utilizes the natural features of the space. Keep the truly valuable things below the upper chambers so it’s harder for attackers to find them.

Show, Don’t Tell: Do not underestimate the ability to incorporate aesthetic details in your base that make it special and identifiable to you. Maybe you use a particular block in all your builds, a recurring structure element in all your builds, a unique architectural design, or a signature paint color that always remains consistent.

Use Different Materials for Variety

Underground bases that consist solely of cobblestone or any other one or two types of blocks can be monotonous. Using a variety of materials will give depth and realism to your structure. To maintain variety, divide your design into areas based on different materials. For example, one section with stone walls and wooden floors and another section with brick walls and cobblestone floors. The choices of materials are vast, so you can get creative with building materials to give your structure a unique look.
