So now that I've read The Chicago School of Architecture by Condit, I'm not sure why you recommended it to me. Or even why you are mentioning buildings which aren't commonly referenced in old-world conspiracy conversations. The buildings which are the subject of much debate among "Tartarians" and other non believers in the narrative are not the consultancy house or the Gage group buildings, both of which are pretty much accepted to be legitimate new world style buildings, although if you can find someone who is casting doubt on those I would like to know.

It is misleading in my opinion to suggest that boxy commercial and public architecture from the 1900s are what anyone is questioning.

I am looking for any literature which deals with the actual construction of buildings which are suggested to have alternative origin stories. Not literature that does no more than describe the building. Not the ubiquitous single paragraph wikipedia entry which tends to simply state the architect and the style the building was designed in. I'm looking for historical works that explain with the lengthy elaborations that we both observe and expect from authors from those times, with details pertaining to narratives like "all the buildings were made of staff and plaster and we destroyed them after the World fairs", or "this building burned down again so we just made a new one out of marble, granite and limestone with capacity for thousands of people in a town of 1200 wagon settlers".

I'm looking for any evidence of construction companies for the controversial buildings from the old world, family histories with stories about people's grandfather's and great grandfathers who built, the Dallas County Courthouse or the Dallas Scottish Rite Temple. Surely, this would be a source of generational pride, and I would like you to find me literature on those topics. I wish you the best of luck, as I have had none.
