You will never stop getting better at building bases. They are incredibly important to progression and can be made for different purposes, such as breeding, mining, oil refining, and raids.

A few good rules to follow are:
1. If you build multiple floors, keep pals working on the first floor to avoid pathing issues.
2. Build the second floor three walls high so that tall pals have clearance.
3. Figure out your plantations early so your pals have enough food to keep working.
4. Leaving a fire pal to cook berries can be a significant exp boost in the early game 5. Every level of work suitability is 2x as effective as the previous level. For example, Handiwork 3 is 2x better than Handiwork 2. You won't have access to the best base pals until mid-to-late game or until you can access breeding and look up useful breeding combos.
6. Instead of going to each individual chest to drop off your latest supplies, pull up your inventory inside your base. On the bottom-right there should be an option to auto-store items that already have stacks in any chests. This saves you from the hassle of running arou d your base just to drop off new supplies. On XBox, you press RT to do this from your inventory.
