I one time unravel why old dutch city centers are so enjoyable to just walk around. I had somewhat of an idea but it was insufficient for the millage. Bothered me for decades hah.
One ingredient was that each building was added to the whole one by one, they could build anyplace as long as it didn't piss anyone off. Those who had money build big luxurious and in the face, those who were poor build some place out of sight, say at the end of an alley and everyone in between found their place to fit their thing. Some wanted to look more wealthy than they were, some wanted the opposite. On a slightly curved road one side is small on the front and large in the backs while the other side offered the opposite.
The final clue came as an old painting of a road that currently has the most expensive buildings in the city. They are 3-4 floors and have all kinds of attachments and expansions. The garden borders on the harbor and sits one floor lower than street level.
In the painting however the brick work was terrible, the attachments were made of rotten wood. Then it struck me the painting was some spot half way in 500 years of "cardboard" prototyping. If a building or pig shed was ever so slightly in the way, slightly misplaced or didn't fit in it didn't survive in the long run. Eventually someone would correct it again and again until they got it right. Then when they got the shape right they would rebuild it the same or upgrade it. In the last cycle over the last 60 years the old monuments got floor heating, AC, modern wiring and plumbing, some even got new floors and a new foundation with the building still standing. It's not done, it's never done.

The second building has the wrong color bricks at the top and the 4th has these cheap ugly modern windows in the roof that should really be deleted.
The scaffolding really completes the story.
