I rather like both buildings!
Reading the article I posted above, it does look that the intent was to be 100% Aymara Native, rather than a copy of Art Deco. But all things being equal I can't see anyone in this planet isolated enough to not have been influenced by Art Deco in some way.
Mamani is in fact an Aymara Native himself. He's borrowed the aethetics from his cultural background, and it does look like an alternate Art Deco. It's a very interesting exercise when one postulates what an alternate reality culture or a civilisation far away on another planet would develop in lieu of Victorian and Art Deco aesthetics. It reminds me of the aesthetics of a Japanese Anime called "Wings of Honneamise," a Space Age Cold War tale that takes place in another planet dominated by two large countries hostile to one another. The flavor of the aesthetics were clearly Asian, but they re-imagined a Diesel/Space Age society similar to that during our Cold War Era.
