Is it time to upsize? When should you upgrade to a bigger house?

1. A growing family. With the family expanding and kids getting older, they will need their privacy and space.
2. WFH. A space dedicated to work and study will feel like a workplace and thus, will increase your productivity.
3. Hobbies. Gardening, painting, riding, and exercising are just some hobbies that require extra space.

Any other reasons why you would upsize?
