In Hangzhou, China, the Regent International apartment complex, capable of housing up to 30,000 residents, has gained viral attention for its vast scale and self-sufficiency. Designed by Alicia Loo, known for the Singapore Sands Hotel, this 675-foot tall, S-shaped building is currently home to about 20,000 people, making it one of the world’s most densely populated residences.

The complex includes a wide range of amenities, such as restaurants, pools, grocery stores, and even nail salons, mirroring a complete town within its walls. This setup offers unparalleled convenience and has attracted many young professionals and students, with rents ranging from approximately $200 to $600 per month.

Despite its innovative design and sustainability praises, the building has sparked debate over living conditions in such high-density environments, with concerns about privacy and limited outdoor access. However, some units feature balconies, providing residents with some private outdoor space. Regent International exemplifies a bold approach to urban housing, balancing massive capacity with the challenges of communal living.
