In this guide, you will find how to decorate the treehouse in The Sims 4 (Growing Together). You can decorate it if you are controlling a teen or child sim.
The first thing you will need to do is to control a teen or child sim and click on the treehouse. The “Set Decorations” will appear on the screen, and you can select the decoration you want.
Remember that toddlers, infants, adults, and young can’t decorate the tree house. Only child and teen sims can decorate the treehouse.
You can also remove the decoration by choosing the Undecorated option.
