Tier

Some blocks have tiers when used to construct a room. The tiers of the blocks used to construct a room determine the room's overall tier level, which affects what crafting stations can operate in it: for instance, the Anvil requires an overrall room tier of 1 before it will function. The overall tier of a room also determines the maximum skill points that can be gained from furniture placed in it.

Higher tier blocks require more advanced skills and crafting stations to produce, and in turn allow for a higher housing skill point cap and more advanced crafting stations.
