A look inside China’s “dystopian” apartment block housing 20,000 people

If you thought your New York apartment building was packed, think again.

In Hangzhou, China, the Regent International Apartment Complex takes “city living” to a whole new level — reportedly home to a staggering 20,000 residents.

Dubbed a “dystopian apartment block” by some, this S-shaped behemoth isn’t just about high population density — it’s a vertical city designed so self-contained that residents could, theoretically, never leave. There are 5,000 apartments, gyms, swimming pools, supermarkets, restaurants, salons, internet cafes, and even schools and hospitals, all under one roof.

The complex started in 2013 as a six-star hotel concept designed by Alicia Loo, chief designer of Singapore’s Sands Hotel.

But economic realities transformed it into a residential giant, now popular with students, graduates, and young professionals. Studios without windows rent for around 1,500 RMB ($210) a month, while larger apartments with balconies go for 4,000 RMB ($570) — a fraction of New York’s $4,000+ monthly rent.

Standing 675 feet tall, its striking design and endless amenities draw curious tourists from all over.

Life inside the giant
Walking through Regent International is like wandering through a mini city. Sky bridges and long hallways connect multiple blocks, allowing residents to access nearly everything they need without stepping outside.

Apartments vary from compact studios to multi-bedroom units, all designed with modern finishes, open-plan layouts, and huge windows offering panoramic city views.

Common spaces are plentiful: swimming pools, gyms, restaurants, and food courts are scattered throughout, making it convenient to socialize or relax without leaving the building. Lower floors host supermarkets, retail shops, and more — basically, everything your average town provides.

The complex also features smart technology and sustainable infrastructure, including solar panels, rainwater recycling, and advanced HVAC systems. Security is top-notch with biometric access controls and CCTV coverage, giving residents peace of mind while navigating the enormous space.

A vertical society
But while convenient, living in a building this large raises some big questions.

A self-sufficient vertical city can foster community within walls but may also create social isolation from the wider city. Residents might know their neighbors well but rarely engage with the outside world. Social stratification is evident, too, with better apartments and amenities located on higher floors.

Critics argue that the design prioritizes efficiency over aesthetics, with repetitive geometric patterns and a stark, utilitarian feel.

Noise, lack of privacy, and the psychological impact of living in such a dense environment are all potential challenges. Yet for many, the building is a modern marvel, combining convenience, affordability, and sheer scale.
