This man knew what he was doing , a doiseño who has been around for decades and is still standing , I read the whole post , even the part that says that each person had their own window , I think the same as you , I guess they decided how to do it and the architect did it .
A very interesting post that shows that many people work, but not all of them do it well, let me explain, nowadays buildings and even roads are inaugurated and very soon they need to be recovered, and buildings collapse very easily, well, I guess in those times CORRUPTION was not very constant like now
