You can earn Design Points by unlocking furniture, clothes, new rooms, and cleaning rooms. Increasing Design Points allows you to receive rewards and earn Designer title badges.
There are three leaderboards related to Design Points: Global, Local, and Club.
In Modern Nest, you can unlock new room Blueprints, which provide new furniture arrangements and new perspectives of the rooms.
Modern Nest also offers Curated Plans for rooms. You can refer to them when choosing furniture to set up your rooms.
