Bigger Barns and Coops?

[Kristenia]

Is there any way to purchase a bigger barn or coop blueprints or upgrade them after purchasing and building the blueprints for the small ones?

Yes

Yes they will come later on and you will receive mail when they are available

After progressing further in the game, you'll be able to purchase a larger size barn and coop. And if you choose to "remove" the ones you've already purchased, you can reuse the stones/logs that were used, towards your newer ones :>
