Southwest Detroit Hospital (1975) by Eberle M. Smith Assoc.
The 1980s architectural guidebook I used on my trip states, "The building's materials were selected for lightness due to low bearing capacity of the soil and to resist industrial fumes generated nearby" Seems like the perfect spot for a hospital.
I didn't even come close to going inside, but this article tells the story.
