The production design for the Harry Potter films has always been pretty amazing, especially starting with the third movie Prisoner of Azkaban. You’ll see plenty of unconventional structures in that universe, and this is a great example, the Shrieking Shack. I won’t go into details of the story (no spoilers here) but you don’t need them to appreciate how wonky and kattywompus this thing is architecturally, and that kattywompusness is captured perfectly in this version by builder Xenomurphy.
