Concept Overview & Architectural Design
A futuristic underwater habitat resting on the ocean floor, featuring interconnecting glass geodesic biosphere domes, submarine docking bays, and kelp farms.
Step-by-Step Structural Guide
-
Clear a circular perimeter ($15times15$ blocks) on the ocean floor, anchoring the base with polished deepslate and sea lanterns.
-
Construct a hemispherical geodesic dome using cyan-stained glass and smooth quartz structural ribs.
-
Clear water from inside the completed dome using sponges or fire-charge drying mechanics.
-
Build an airtight airlock entryway using iron doors, redstone repeaters, and waterlogged soul sand bubble elevators.
-
Connect multiple dome pods with pressurized glass transit tunnels framed in oxidized copper.
-
Fill the interior biospheres with lush flora: tall birch trees, moss carpets, and automated crop harvesters.

Pro Builder Tip
Conceal conduit power blocks directly in the center of the seabed foundation to grant permanent underwater breathing and night vision within the entire base perimeter.
