World’s LONGEST apartment block has 15,000 windows, 170 front doors & locals need a bus to get from one end to the other

THIS is the world's longest apartment block that boasts 15,000 windows and 170 front doors - with locals needing a bus to get from one end to the other.

The unbelievable complex in Ukraine's Lutsk is referred to by locals as "The Great Wall of China" due to its ridiculous size.

This residential block is believed to be the longest apartment building in the world - and was built in the 1970s.

From one end to the other, the complex measures an unbelievable 5,741ft - but this does not include all the turns that there are due to its structure.

Including the jagged twists and turns of the building, it measures up at a shocking 12,336ft.

It's much easier to hop on a bus than it is to walk from one side of the building to the next.

During Ukraine's time of socialism and early industrialisation, residents flocked from villages to cities for work or education.

Due to this immense change, the government had to keep up and therefore made more affordable housing.

They did this by building incredibly large apartment complexes - just like the honeycomb structured building in Lutsk.

Despite this being the world's longest apartment block, the complex's own residents aren't even aware of this incredible fact.

There are no markings nor accreditation to the building to say that it holds the record.

Similarly, there is a Chinese town where all 20,000 residents live under one roof - and you never need to go out.

The Regent International apartment building in Qianjiang Century City, Hangzhou’s central business district, is like nothing you've ever seen before.

Initially designed as a hotel, this mammoth structure has been turned into thousands of high-end residential apartments.

The S-shaped Regent International now accommodates for up to 30,000 residents, although it's current inhabitants stand at around the 20,000 mark.

Nonetheless, the remarkable congregation of locals crammed under one roof makes it one of the most densely populated areas in the world.

But the impressive building, which stands at 675ft tall, is more than just a place to call home.

Also located across its 36 to 39 floors, depending on what side of it you’re on, are a variety of amenities and businesses - just like any normal town would have.

Available for the 20,000 residents is a giant food court, as well as swimming pools, barber shops, nail salons, medium-sized supermarkets, and internet cafes.

With everything quite literally on your doorstep, there aren't many reasons for people to leave the building.

It's highly likely that some people never step foot outside at all.
