Modern Underground House

Zaypixel never fails to amaze audiences with the creative builds and this time around it is an underwater base that is also underground! Can you imagine? To build this one yourself, you have to dig down 16 blocks in any water body as you like. The tutorial shows many floors that are decorated with concrete, dark oak, and a small Nether portal to go in and out whenever you wish to.

We love the use of Sea Lanterns placed behind the paintings for extra lighting effect. There are other hacks as well, like using a Magma block to enter and exit your base, another one is a water elevator along with Soul Sand. Decorate using items found around the coral reef or use seaweed for decoration.

Underwater Seabase

This Underwater Sea Base design by Goldrobin will remind you of a lot of Subnautica’s builds. At the ocean bottom, it has a base pillar and a 360-degree view below the water. All of us know it is a must to use a lot of Glass blocks for a hideout underwater. We always love to appreciate Minecraft’s underwater bases that use the new wooden blocks from the Nether biomes especially if it fits perfectly with the color palette. You don’t always need to create big houses for yourself to be unique and this idea is good proof of it. 

Here is a tip: if you want to empty water inside the building but do not have Sponges, what you can do is to construct an outer frame and completely seal it. Once that is done, fill the inside with gravel or sand.
