Hundertwasser - In the Meadow Hills
I'm very new to Solarpunk, but Hundertwasser seems to gel very nicely with what I've seen of the ethos.
He has designed, and actually implemented many buildings which tightly integrate nature into the urban environment.
His political views leave a LOT to be desired but his work is extremely inspiring.

I don´t know anything about his political views but I adore his architecture (and I hate most architecture in general). What´s not to love about houses that look like children's drawings full of trees :D
Wow those are some beautiful examples there!
