- Use tech to get a lot of money, you'll need it for the next steps
- Move or renovate to get huge floor-to-ceiling windows. This is a rich people thing so you might already be filtered, but it's important for the look
- Use furniture with simple geometry. All angles should be 90 degrees, if possible. There should be very few amounts of lines in the contour. Don't put ANYTHING complex in your room, like a fucking chandelier full of ornamentation, or a free-form LED lamp.
- Utilize "negative space" (google it). Also google "Interior design rhythm", they use the law of 3 with the wall art, and probably with the black planters too.
- Also important: White walls, ceilings and floors. Install a "false ceiling" and install diffused light panes in it.
How can you do this in your west slav foresthole? Well despite how "empty" it looks, you need a lot of money to afford this. Your best bet would be to emulate it using much cheaper solutions, and hope that it will be "close enough".
