How were the first apartments in 2nd Century BC Rome built?

Ancient Rome had over 40,000 apartment buildings for commoners, reaching up to 7 stories. However, they frequently collapsed. The emperor then legislated height restrictions, but this led to a shortage of housing for a million people. The solution wasn't to thicken the pillars, but to change the entire wall into a frame. They poured concrete, encased it with bricks, and hid arches above each door and window to divert the weight sideways. In the port city of Ostia, you can still see these arches exposed above the windows.

Distributing load with arch structures to solve housing density issues, that's the essence of Roman engineering. Thanks to your thorough explanation, I learned something new today, hmm!

It's amazing they built structures like that back in the 2nd century BC. I wonder how far Roman technology would have advanced if the empire hadn't fallen.

It's amazing how they used the walls themselves as the frame instead of making thick pillars 😳

The concrete material must be Roman concrete mixed with volcanic ash.
