>>19467745Here's a steel idea inspired by the picture of the Church of the Ascension of Christ on the "Magnetic Mountain" wiki.
The gym is like a church to hard labor, steel and Soviet ideas. It combines factory aesthetics with Russian orthodox aesthetics, it's a temple for steel and steel workers.
I can also see the onion-domed towers functioning as chimneys for furnaces.
It doesn't quite fight Stella's character though.
