The most important thing to know when you’re getting started building is construction parts work in layers and tiers so to speak. A lower tier (more foundational) part cannot be supported by a higher tier (more flimsy part), e.g. you can’t put a stone foundation on top of a wooden pillar.
Tier 1 — Can support the most
Tier 2 — Can support medium loads
Tier 3 — Can support the least
Tier 1
This tier includes your big meaty foundation pieces, including:
Stone Foundation
Small Stone Foundation
Stone Wall Foundation
Stone Stair Foundation
Triangular Stone Foundation
Tier 2
This tier includes parts that aren’t as beefy as full size foundation pieces, but can still support substantial loads.
