Dome buildings

Wonder

Salvage & Prefabs

Dome buildings are placed inside domes. As a result building space is limited and the size of each building must be taken into account.

Maintenance: Buildings require maintenance over time. They are maintained by a drone working on them at the cost of resources. If they are not maintained, they will stop working. This is represented in the building's infopanel by a bar which fills up, turning from green to orange to red the closer the building is to breaking down.

The required type and amount of resources for maintenance is shown to the right of the bar in the Maintenance section of the building's infopanel. Hovering over this section with the cursor, or gamepad selection, shows further details such as Current Deterioration % and Hours Since Last Serviced.

The amount of time a building can operate before being maintained can be set differently for each building, and is further reduced by dust and disasters. A building using default settings with no exposure to dust or disasters will operate for 166.67 hours (about one Martian week) before requiring maintenance.

Production

While most production buildings are placed outside domes, a select few must be placed inside.

Life Support

While most Life Support buildings are placed outside Domes, a select few must be placed inside. Life Support buildings operate on a single work shift.

Housing

Homes are the living spaces for individual Colonists. Each Colonist recovers Health and Sanity when resting at home. If their comfort is lower than the residence's Comfort value, they also gain comfort equal to its Comfort Increase. Colonists will lose Health if they have no home. Many residences have multiple visual variants, with an extra one being available if the Colony Design Set DLC is installed.

Education

Education buildings give colonists Perks or Specializations to be more productive. All Education buildings have a capacity of 5 Colonists per Shift and the night shift causes Sanity loss.

Research

Main article: Research

Research buildings produce research. Research Labs have an additional visual variant if the Colony Design Set DLC is installed.

To get the most research per worker, try building 3 Research Labs (44 per worker), then a Hawking Institute (42), then a 4th Research Lab (39), then a 2nd Hawking Institute (38), then a 5th Research Lab (33), then finally a 3rd (33) and 4th (29) Hawking Institute. A sixth Research Lab is still only worth 1500 but takes more jobs (28 per worker). Every Research Lab after the 6th provides research at a rate of 28 per worker. A 5th Hawking Institute is not worth building since it only provides 25 per worker. See the Collaboration Loss column for more details.

Dome Services

Dome Services buildings satisfy the needs of Colonists based on the building's Service Comfort, and the max Service Comfort can be increased by the building's performance. For example, a Grocer at 150 performance will be at 60 Service Comfort instead of 50. Additionally, if a visitor with 59 Comfort enters the Grocer with a Service Comfort of 60, the visitor will still get the full +10 Comfort and end up with 69 Comfort.

Colonists will visit a Dome Service building only if the provided Services match that Colonist's Interests. When a Colonist visits a Dome Service building, they gain +X Comfort if their Comfort is lower than the building's Service Comfort value. X is the building's Comfort increase (Not shown in game).

Spires

Spires are built in the center of the Basic, Medium, Mega and Geoscape domes. The Oval and Diamond domes can have 2 spires. In the Green Planet DLC the Capital City Wonder can have 3 spires.

The Prefab Compression breakthrough allows Spires to be bought from Earth as Prefab buildings; even Spires that have not been researched yet with the exception of the Cloning Vats (requires the Cloning breakthrough) and the Temple Spire, which is only unlocked when playing with the Church of the New Ark mission sponsor (comes with the Space Race DLC).

Decorations

All decorations satisfy the need for Relaxation, Exercise and Playing. Also, every decoration can support 1 Visitor per hex. So a Large Garden can support 10 Visitors since it's footprint takes up 10 hexes. Aside from the Projector Lamp, Decorations do not consume any Power or Maintenance.
