(For us, that meant oranges) Try to avoid cutting down trees and destroying rocks on your own island. You’ll also want to keep whatever your native fruit is handy as opposed to selling them for a while. You’ll be on the lookout for all three types of wood (wood, softwood and hardwood), as well as Iron Nuggets. You’ll need a lot of wood, so getting this all together can take more than one day, or require you to go off island using a Nook Miles Voucher. You'll drop interior items into the box near each plot, while exterior items should be set up just alongside the construction tent.
While you’re still at Resident Services, construct a simple workbench and bring it along with you, so you can craft on-location near the three construction sites.
Each plot requires you to build 6 items, 3 interior and 3 exterior items.
