Green

You press the green button and shortly after you are on the corresponding floor.

70% of the total building costs. Located significantly lower than the other floors. Nature.

There's no way that behind that door is what's quietly on your mind. It can't be. That would be... absurd.

A small garden. That's probably it. A small underground garden, with lights like in a greenhouse and sprinklers. That's what it'll be.

So that's how you open the only door on the Green floor.
