I have read about this Ballwin property for years but have never encountered it in person...
I stumbled upon it during showings this afternoon and I must say... it is indeed an interesting case study of the rights of a property owner versus the city they reside in. This former HS art teacher transformed his home into a piece that he named "The Holocaust Revisited" as a Holocaust remembrance. He has been fined and jailed for his work, yet the piece continues to grow.
The traditional 2-story next door (bottom right photo) shows the dichotomy between the artist's home and the traditional West County suburban neighborhood around it.
