A Cosmopolitan home is one that is clean, crisp with usually a simple colour palette and modern materials such as metal, glass and steel. Simplicity is definitely a key word here, and if you like the modern style you border on the line of minimalism without quite crossing over.
If you like this style, you can achieve this in your home by adding simple pieces to your home in neutral palettes.
There are many sub-genres that are part of this style!
