It's not "crafted visually first."

Growing moss or sod on your roof helps regulate the temperature indoors, which is good for the environment.

Growing plants on the façade does the same thing. And both of these practices increase space that can be used for plants that capture carbon, purify the air, and lower surrounding temperatures. In addition to increasing space for crops, or pollinator gardens.

Unless you think a solarpunk society needs to eliminate cities, then plants on buildings is an integral idea not just to the aesthetic but also functionally.

And even in villages, it's a good idea.
