Imagine living in a building so large, it had everything you needed in one place so you never needed to go outside.

Well, what sounds like a dream for some and a nightmare for others, is actually reality for at least 20,000 people in China.

In Qianjiang Century City, Hangzhou’s central business district, is a colossal complex called the Regent International.

And luckily for the residents living there, they have everything they need inside the building.

Unless you’re craving a breath of fresh air, there’s next to no point in going outside.

The S-shaped building stands at an impressive 675ft tall, and covers more than

260,000 square metres of space.

With a LOT of people to house, it comes as no supposed that it’s one of the largest buildings in China.

(It can even accommodate 30,000 residents, a whole 10k more than current!)

Spread across the building, there’s a variety of amenities and businesses situated across 36 to 39 floors – just like you’d find in any average town.

This includes a massive food court, swimming pools, barber shops, nail salons, medium-sized supermarkets, and internet cafes.

It might sound like a lot, but it’s the blending of residential and recreational spaces under one roof has led some to label it ‘the most sustainable living building on Earth.’

The building has gained a lot of attention on social media, with with users amazed at its impressive size and unique way of living.

One TikTok user showed the immensity of the building with drone footage, whilst

another TikToker even showed a brief tour inside the building, pointing out a restaurant on the 32nd floor that accommodates the entire building.

Social media users are speechless at the number of inhabitants it boards in one single building compared to their hometowns.

The building was designed by Alicia Loo, the chief designer of the world’s second seven-star hotel, the Singapore Sands Hotel, and was initially set to serve as a six-star hotel.

However, it was transformed into thousands of apartments, and is now an iconic part of Hangzhou’s cityscape.

Wondering who lives there? Well, it’s mostly convenient for graduates, as well as students who are about to graduate, both of which take up the majority of residency.

Additionally, young working professionals, such as influencers and small business owners, are reportedly a common type of tenant.

The apartments aren’t too unreasonably priced either.

Small apartments without windows usually go for around 1,500 RMB (£167) per month, according to Chinese news agency Sin.

Whilst larger units with balconies can be rented for up to 4,000 RMB (£445) per month.

Could you see yourself living somewhere like this?

Ever been in a hotel so big that it’s made you wonder just how many people could live in it if every single room was full, and if its guests never left?

That’s basically what has happened in the massive Regent International in China’s Qianjiang Century City – it was built to be a hotel, but those plans were abandoned and it’s now simply an enormous block of apartments, with an astonishing 20,000 people living there.

The Regent International is 675ft tall, making it a huge building, with an unusual S-shaped design.

Amazingly, those 20,000 residents haven’t even filled the building completely – its maximum capacity is around 30,000 people, so there’s room for another 10,000 to arrive.

Those are slightly mad numbers, and things become even more dystopian when you learn that the building houses a whole bunch of amenities so that these 20,000 people don’t have to actually ever leave.

There are shops embedded in the building, including a food court, nail salons, swimming pools, barbers, supermarkets and internet cafes.

This means that basically every need you might have should be available within the Regent International, making it a sort of town in a building (with a pretty chunky population compared to many towns, too).

For such a huge building, there aren’t that many ways to glimpse its interior, though – residents don’t seem to have posted much about it.

Instead, we’re reliant on scant social media clips that have emerged, including some pretty amazing exterior footage of the building’s sheer size captured by drone.

One TikTok creator did show a little of the building’s inside as she apparently made her way around it, although you only really get to glimpse the building’s foyer, rather than getting a real sense of the geography of its corridors.

Still, people in the comments under those videos are in awe at the scale of the building – one person wrote: “My town only allows for minimum 1/2 acre plots. My neighbors are still to close even with that. I could never live in that building.”

Another asked an ironic, but quite fair question: “If you work in that restaurant and live in the same building; are you working from home?”

Just think about it – could you happily live in a building of this size? After all, it’s one thing living in a mid-size apartment block, but quite another living in one of the most densely populated buildings you could possibly hope to find. Just think of how many neighbors you’d have!

If you’ve been anywhere on the internet this week, you probably would have seen the absolutely wild building in China that has room for 30,000 residents.

The enormous building has been getting a lot of attention on social media in the last couple of weeks as drone footage showed off its sheer scale, with people getting their heads around the fact there are 20,000 residents in it (with room for 10,000 more).

TikTok user Yasmin – whose handle is @official_yasmin – took the bold step of actually going to the Regent International to have a peek inside.

As she enters, we get a glimpse of what looks like a really lavish entryway on the ground floor. This makes perfect sense, given the building was initially planned as a six-star hotel before it was turned into residential apartments.

The most interesting segment in the TikTok, though, comes right near the end, when Yasmin says there is a huge restaurant on the building’s 32nd floor. This is apparently open to all residents, although you do need to book into it.

That’s no surprise since it doubtless can’t feed 20,000 people at once – but we’re sure it’s still a massive space.

And the restaurant isn’t the only amenity in the building. If you wanted, you’d never even have to leave the Regent International – as it’s also stocked with supermarkets, nail salons, hairdressers, fitness centers and more.

The comments under Yasmin’s video are full of people trying to digest the size of the building, as you’d imagine, but there are some funny observations.

One comment asked: “If you work in that restaurant and live in the same building; are you working from home?”

And people can’t get over the scale of it all, with another observing: “My whole town fits in there with 10 thousand people to spare and literally rn as many people as my town live there.”

The Regent International is indeed seriously large, but it’s surprisingly affordable if you wanted to join the 20,000 people there right now – you can get a small apartment for as little as $210 (albeit one without windows).

Russia houses the world’s most crowded apartment block, a place so gigantic it’s been nicknamed the ‘Human Anthill’ or ‘Cheloveiniki’.

Located in St. Petersburg, the colossal building houses 18,000 people across 3,708 apartments and 25 floors.

Most apartments are one or two beds and it averages around four to six apartments on each floor.

Of course, with a building so big, residents need an easy way of getting around and so each section of the complex contains four fast-traveling elevators.

Since its construction in 2015, the Human Anthill has gained a lot of popularity.

The block’s first floor is rented out to businesses which eliminates any kind of commute, making it a true city within a city.

According to one Russian resident on social media, the building includes seven food shops, three beauty salons, a private kindergarten, numerous cafes and a post office.

They also added that they ‘once spent half a year without leaving the premises’ due to having everything they needed inside the complex. Plus, parking is free.

Surprisingly for a place with people crowded together, there is reportedly ‘no disturbances or ruckus’ as the walls are thick between apartments.

One Reddit user says they’ve lived there for eight years and appreciates the environment and convenient location for working professionals. Plus, as many apartments in St. Petersburg apartments are ‘old’ and ‘too expensive’, another user believes the building makes an affordable option for commuters.

However, living in such a large building does come with challenges. For example, elevator lines can get long in the evenings, like public transport queues.

Originally, apartments in the Human Anthill were quite affordable at around £30,000. However, prices have since risen, with new two-bedroom units now costing about £76,000.

YouTuber Peterbruh did a tour of the residential building, showing everything from the outside to the inner lobby and the views from atop.

Some viewers were impressed at the clean state of the building given its size.

‘That was nice too see the inside of one of these huge apartment buildings. Its impressive how clean and organize the seems to be. With so many people living in one,’ one replied.

‘Those buildings are incredible. They must house so many people,’ another added.

Other Reddit users have been wondering how certain scenarios would pan out, say food deliveries or a fire evacuation.

‘imagine the group chat,’ another user remarked.
