It's simply an accepted fact that the whole point of the game is to play around with different cultures. They are simply all played within the rulest of the underlying boardgame.
Some human cultures didn't make cities (and maybe what passed for a city for some would be deemed a series of villages by others), some cultures didn't even make permament encampments.
Some found value in architectural works, others did not. Some find value in antiquity, others tore down old buildings after a set time to make newer versions of them.
Unless you introduce different handling of cultures that are at odds with the boardgame model undeneath, you'll simply have to accept that most of these things are the same sort of squinty-eyed concession to find something roughly equivalent to an idenitfiable local construction that serves a special purose and involved a great deal of masonry, organised workforce, planning, all that stuff. You can sometimes find something a little less mundane here and there (artificial lagoons, weirs and totems of the NW Coast) but it will never be comparable to giant palaces, cathedrals, fortresses or factories that are the thing "unique infrastructure" is supposed to represent in an ideal scenario.
There are no "Star Chart Lodges". It's a standard home of the Pawnee. These were built with specific orientation in mind (we don't have a 'California' civilisation with a house built according to fengshui rules as their unique infra.... at least yet

), but they were still "a house" as Mr. Salt puts it. I'd rather look for other avenues of representing their culture (more unique bonuses while forgoing the unique infrastructure altogether?) rather than fetishise what's there but doesn't sound or look cool enough on its own.
In this case, the Pawnee earth lodge is a concept that is unique insofar as settled people like us are concerned. They are permanent dvellings built for specific seasons of the year. So that the community would return to these during harvest and planting season while living as foraging hunters in teepees offseason. They even used astrology to set these up due to their belief system and class organisation, they weren't completely random dugout homes devoid of any planning or reason. So in the end they are a house like any other, not an observatory or palace, but the way they are
used as houses is what gives them an interesting quality.
Of course, that's a nice bit of lore on Civilopedia, but getting any of the game mechanics to play ball with this concept without herd hunting, nomadic lifestyles or changing of seasons is the tough/impossible part.
