Inside China's 20,000-Person Megabuilding: Regent Intl Hangz

China is facing enormous housing pressure in its major cities. Regent International in Hangzhou was built as a solution — a single apartment complex designed to pack up to 20,000 people into one building. What was once promoted as an efficient model of urban living now raises serious questions about overcrowding, livability, and sustainability. From the outside, it looks like a futuristic megastructure. From the inside, daily life feels very different. In this video, I explore one of the most extreme apartment complexes in China to show what living inside a 20,000-person building actually looks like.
