How building progression works
Your Sanctuary is the centre of settlement progression, but higher Sanctuary milestones can depend on other buildings being ready first. The checkpoints below collect the requirements that are present in our current source snapshot so you can see likely blockers before committing resources.
Sanctuary checkpoints
The table is most useful as a planning reference: find the Sanctuary level you are approaching, then compare the listed supporting buildings with your own settlement.

Planning around blockers
Do not assume every unlisted level has no prerequisite. This guide does not infer missing levels, costs, timers or a universal optimal build path. Live-service requirements can change and the source snapshot is incomplete between recorded milestones. Use the detailed Sanctuary page when you need the underlying milestone notes.
