Undersea resort

How-To with The VALiens: Building an undersea resort

Step One

To begin, find a fairly deep spring or lake. As of 1.8, Ocean Biomes can be used as the location.

Step Two

Using any block (e.g.Dirt or Glass), construct any size column equal to or larger than a 3×3 column from the sea-floor to the surface. Dig a hole down the middle of this new column until you reach sand. This is your entrance. Or you could construct the column 3×3 from sea floor to surface then dig a hole down in the middle of the column as said above until you reach the sand floor. Then dig three more blocks down. Add a ladder to the first sand block which is the sea floor. Go back up and destroy the column and then, since there is a glitch, the water will not go into the hole you made.

Step Three

Construct rooms by first creating the walls and ceiling underwater, then filling it with sand to dry. Edit: Any type of block will work as what you are doing is destroying the water source blocks without them having the opportunity to refiill from excess water around them. Or, if using my design, dig one more block down for counter measures and then build your rooms as said above. Edit 2: In my opinion, Wood (Planks) works best. When you are done, you can just burn it all out Edit 3: Wool burns a lot faster than wood planks, but they are harder to get.

Step Four

Repeat step three as many times as desired. Note that if there is soilon the ground, it will be very fertile, so make crops if desired. (note this is much easier with respiration helmet)

Alternative Methods

Alternate Method 1

To begin, find an underwater mound of dirt or stone. Next, dig or break a 2 block deep hole in the mound and put a wooden doorin the hole to stop the water. Next, go in and carve your cave out and you’re good.

In SMP, especially if it is set to PvP:true, you want to keep your mines and bases as secret as possible. Find a random spot on the bottom of the ocean. Be sure not to mark it. Start digging a 1×1 shaft downwards (this is easier with a shovel). Come up for air when needed. Dig down until you hitstone. Once you hitstone, mine the first two blocks down, then come back up and start digging horizontally. This will not make your waterelevator/ladder go directly into your home. Start digging downwards in a step pattern. Once you think you’ll have enough room to make your house, you’re good to go.

Another Good Option

For this option, you must have a sizable amount of glass (for the walls), wood (for filling), some ladders, a small amount of stone or dirt, and a method of creating fire (Flint and Steelis preferred). Create a solid block of wood underwater that fills the basic shape of your house. Build an entrance as described in step 2 and put Ladders in it. Dig down one block to get to the wood, set it on fire from the safety of the ladder, and then wait until it finishes burning – you should have an underwater glass dome.

Alternative another good option

First need something for walls, about one full stack of dirt, lava in bucket(one is good enough, but if you want to do it faster you need more). Then you make a roof for your base and fill(only roof) with dirt and dig a checked pattern in it. Next you need to fill those holes with lava and wait for it to fall down to the bottom. All hole must be filled(not necessarily at the same time). After it you put something like cobblestone or what you want the base to be build on these holes(take the lava first!!!) and dig the other blocks of dirt that left and put lava in that holes, take it out and fill with proper material. Now you just build walls destroy the leftover springs and it’s ready to use!

Alternate Method 2

This is for people who can’t use ANY of the above methods. Materials: 6 wood (To make a door), 25-64 dirt (depending on how big you want the house to be), and 25-64 sand (for the air bubble in the house). Steps: Step 1: Build your basic house out of dirt underwater. Tip: Leave a door entrance!!! Picture: It should look (somewhat, depending on how much dirt you used,) like this

Step 2: Add the door.

Step 3: Fill the house with sand. Tip: Remove it quickly!

Step 4: That’s it!

Glass pane/Iron bar Airlocks

With the arrival of the 1.8 update, glass panes and iron bars can be used to make an easy air-to-water doorway. Begin by making a set of glass panes and find a suitable corner of your underwater home (approximately a 2X2X2 space with room above for your ceiling minimum.) Place the glass panes as though you were making a 2-block-high corner window but remove the 2 panes on the very corner. Due to the way the game treats these blocks as full cubes, the “corners” will still be touching and refuse any entry by the water, while still allowing you to walk through into the water.

Alternative Method 3

The first step is obviously finding a deep spot in the ocean. From there, build a tower at the bottom of the ocean and make a column of cobblestone until you reach the surface. Once you do that, go back down and make a 1×2 box, coming up for air as needed. When you have that box, enter it and seal yourself off completely. From there, get a light source, and expand. I use either cobblestone or sand to fill out the rooms. Once you get a good sized room out, start replacing the walls and ceiling with glass.

Alternative Method 4

N.B. This method is particularly good for building in very deep areas of water as it requires minimum time spent underwater.

Find a fairly deep patch (depending on how big you want your home to be) of water with a relatively flat floor. Then, 2 or 3 blocks above the water surface, build a platform out of anything (dirt, cobblestone etc.), finally build the shape of the desired building on the platform out of gravel or sand (as they are both affected by gravity). When you are happy with your mould dig out the platform underneath (beware of falling bricks!) and then all you have to do underwater is build your walls and hollow it out.


  • Doors can be placed on the bottom of the water and provide an air bubble.
  • If building an underwater tunnel to access your base, bear in mind that still water will allow you to pass in both directions at the same rate, whereas flowing water works better for one-way paths.
  • Ladders create an air bubble as well. You can put one at the top of your shaft and it won’t have to go all the way to the surface.
  • Sugar caneblocks water, but not movement. You can use them as air to water doors.
  • Wood can be burned out after removing all the water
  • Sugar cane also sticks to basically anything under water. Place one cane at head height on the outside of your underwater home to create pockets of air anywhere.
  • Ice may form over the surface of your chosen water, generally in colder biomes. Make sure to remove it quickly.
  • You may also see random air bubbles in the ocean. These are a bug. We have not managed to figure out what causes them. We being the minecraft community.
