Not to say this building isn't great, but are those two internal towers in the third image made of concrete there? Is that so to make the elevator shafts (fire resistant)?
- Amygaz 9y agoYes that's the code. They have to use a reinforced concrete structure that is earthquake resistant. It houses the elevators, the stair cases, and utilities. It's pretty standard everywhere for tall building.
