You can use Design Mode to change the way most of the elements in the mansion 🏡 look after they've been added or renovated.
Tap and hold an object (a chair, a wardrobe, a lamp, etc.) to see the available designs and pick the one you like.
Thematic decorations that you get during special events can also be changed into regular decorations 🎄🎃
❗ You can change the appearance of objects, but you can't change their location!
