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.

China’s Housing Disaster: 20,000 People Packed Into One Building

In this eye opening exploration, CN Walking delves into one of China's most extreme urban housing experiments: Regent International in Hangzhou, a mega apartment complex built to house up to 20,000 residents in a single building. The video lays out a stark contrast between the ambitious promise of efficient, vertical city living and the lived reality of crowded corridors, shared spaces, and the daily hustle of a community piled into a monumental structure. The host previews the scale from the outside, then guides viewers through the grand lobby, balconies with city views, and the surrounding green spaces, before widening the lens to reveal the broader building cluster and the open lawns and public areas that host social life, along with a riverside running track that hints at the community’s attempt to reclaim leisure and breath within a colossal footprint. The narrative raises critical questions about livability, sustainability, and the long term viability of mega housing projects as定
