Prioritize a resource-production building first on Oasis Island, according to the supplied draft. It does not name a specific building, so use this as a general priority—not a confirmed upgrade order for a particular structure.

The draft says these buildings generate materials used for other island activities. It recommends upgrading production before branching into utility or infrastructure buildings, then shifting focus when resource production is sufficient for the next projects.

Because the supplied information does not identify building names, upgrade costs, or unlock requirements, it cannot establish which specific building to select or how far to upgrade it. Check the available building options in your game and choose a production building if you need more materials for island development.
