Imagine a place where everything you need — your home, your food, your gym, even your social life — exists within the same walls.
Thank you for reading this post, don't forget to subscribe!For thousands of people in China, that’s not a concept. It’s everyday life.
The Regent International Apartment Complex in Hangzhou has gained global attention for one simple reason: it’s so vast, so densely populated, that it functions like a town — all contained within a single building.
And the numbers behind it are staggering.
The complex is said to house more than 20,000 residents (although some reports go as high as 30,000), spread across around 5,000 apartments inside an enormous S-shaped structure that stands 675 feet tall and spans 260,000 square metres, Parametric Architecture reports.
To put that into perspective, that’s more people than some small towns — all living under one roof.
Originally designed in 2013 by architect Alicia Loo as a luxury six-star hotel, the building was later converted into a massive residential hub as urban demand grew. Today, it’s often described as a “vertical city” — and it’s not hard to see why.
Because this isn’t just a place to live and sleep. Inside, residents have access to what you’d typically find across an entire neighbourhood.
There are food courts, barber shops, nail salons, supermarkets, swimming pools, gyms, internet cafes — even shared spaces designed for socialising and leisure.
In theory, you could live there and never need to leave.
That self-contained lifestyle is exactly what has led some social media users to label it as “dystopian” or even compare it to something out of Black Mirror.
The building’s design leans heavily into functionality. With between 36 and 39 floors depending on the section, and a network of corridors and connections running throughout, residents can move through the complex without ever stepping outside.
The apartments themselves vary widely — from small studios (some without windows) to larger multi-room homes with balconies overlooking the city.
And despite its scale, it remains relatively affordable.
Smaller units can cost around 1,500 RMB per month (roughly £162), while larger apartments go for around 4,000 RMB (£432) — significantly less than cities like London, where average rents exceed £2,100 each month.
That affordability, combined with its all-in-one lifestyle, has made the building particularly popular among students, graduates, and young professionals.
But life inside such a dense environment comes with trade-offs.
While shared spaces encourage interaction and create a sense of community, the sheer number of residents can also lead to challenges — from noise and privacy concerns to a feeling of being disconnected from the outside world.
After going viral on TikTok, people had plenty to say about the unique living situation.
“Having 30k neighbours is like knowing everyone in your town,” one TikTok user wrote, with another adding: “Imagine how long you would need to wait for an elevator.”
A third wrote: “Imagine what happens when the fire alarm sounds.”
Either way, one thing is certain.
When 20,000 people can live, work, and socialise in a single building — the definition of a “neighbourhood” starts to look very different.
