Observatory
The Observatory is a large glass dome room that creates a stunning 360-degree viewing gallery inside your base and contributes +1 hull integrity to keep your seabase resilient in deeper biomes.
Quick Info
Description
The Observatory is a glass dome room attached to a corridor or Multipurpose Room. Its curved glass walls give you unobstructed panoramic views of the surrounding biome, making it a popular gathering spot for crew members. Functionally, it adds +1 hull integrity to your base, helping resist depth pressure while looking great in screenshots.
How to Build
Build the Observatory using the Habitat Builder, attaching it to the side of a corridor or Multipurpose Room. The glass dome is built in a single placement.
- 1x Glass
- 2x Titanium
What it Does
The Observatory combines aesthetics with function: it doubles as a hull-integrity module and a panoramic viewing gallery for watching biome wildlife.
Viewing Gallery
Provides 360-degree ocean visibility; great for watching leviathans or sunsets.
Hull Integrity +1
Adds +1 hull integrity, helping your base withstand depth pressure.
Screenshot Spot
Curved glass creates a beautiful frame for screenshots of the surrounding biome.
Base Integration
Place the Observatory at the end of a corridor to give it a grand view of the surrounding ocean. Combine with Reinforcement for deep-water builds.
Foundation
Anchor the Observatory above a stable Foundation for the strongest viewing platform.
Required anchorReinforcement
Pair with a Reinforcement beneath the dome if you plan to build at significant depth.
Deep-water synergyMoonpool
Build the dome above a Moonpool to watch vehicles launching into the biome.

Map Locations
Build the Observatory anywhere with enough open water for a clear view. Position it near coral walls or kelp forests for the most cinematic views.

What does the Observatory do in Subnautica 2?
The Observatory is a large glass dome room that provides 360-degree ocean visibility while adding +1 hull integrity to the base. It doubles as a viewing gallery and a structural module.
How much does an Observatory cost to build?
An Observatory costs 1x Glass and 2x Titanium, and is built with the Habitat Builder. Glass is crafted from 2x Quartz, so make sure you have a healthy supply of Quartz on hand.
Does the Observatory need reinforcement in deep water?
Yes, place a Reinforcement beneath the Observatory if you plan to build it in deep biomes that exceed your base's hull integrity budget. The dome only adds +1 integrity, so deep-water bases need extra support.
