Exterior decor is unlocked at Level 9 and can be purchased in the Store under the Exterior tab for rubies. Exterior items allow you to add a personal touch to your game with a large variety of furniture and decorative elements to choose from. However, unlike interior decor, exterior items have no effect on tip percentage and there is no penalty for mix-and-matching different styles of exterior decor.
Selling exterior decorations to Carl grants you rubies instead of coins.
Some special items can be won or bought during events. They are not listed here yet.
