Architectural Styles of Theatron

I’m been attempting to make an extended version of Theatron.
The only main issue I’ve been running into is finding a good overall design language for the map.
Essentially I’m going to take what Mr. Sunabouzu created and attempt to extend it to a bigger map complete with a pool, a dance room and a few other components.

I’m thinking somewhere along the lines of Neo-futurism and New Classical.
Does anyone have any examples of this type of architecture?

Perhaps a hint of Art-Deco?
