Looking for picture book about a house that was made of plants. The outside world merges surrealy with the inside room (resembles art of Jacek Yerka but it's not him). Book was mostly visual and the color of the art was very green. The story takes place at night. There is an old man with white hair in the house. Likely an older book from the 60s or 70s, or at least has the 60s/70s hippie/spiritual vibe. If you find this with just this info you are unto a god, thank you.
