The 16 Largest Buildings in the World – Onward, Outward, Upward

From the tall to the wide, the round to the pyramidal, the long and the bulbous, we looked at all 16 of the biggest buildings in the world, for people who know that size is all that matters.

Boeing Everett Factory

Most Total Volume: It’s impossible to convey the scope of the Everett factory in mere photographs. 


Abraj Al Bait Towers in Mecca, Saudi Arabia

Biggest Clock: These towers have more than merely the tallest clock in the world, as the Al Bait Towers also have an approximate square footage of 16,137,600 sq ft. 


Aalsmeer Flower Auction building, Holland

Most Immense Footprint: More than 20 million flowers are bought and sold here on a daily basis. 


New Century Global Center in Chengdu, China

Most Total Square Feet: Though it isn’t the largest amount of total area, the Center has multiple floors that give it more total square footage among the many layers of the building.


Burj Khalifa

Tallest Building: Though the footprint is fairly small, occupying a scant 3,331,100 sq ft on the ground, the soaring spire of the Khalifa reaches 2,722 ft into the heavens.


Masjid al-Haram, Mecca Mosque

Biggest Mosque: Costing more than $100 billion to build, there’s no religious building that even comes close to the 99 acres – that’s 4,312,440 sq ft. – worth of space that is able to house about 4 million worshipers.


Tokyo Skytree

Tallest Tower: Saying that the only thing of note about the Skytree is that it is tall would be a severe disservice to all it does.
