Where Is the Burj Khalifa?
The world's tallest building is in downtown Dubai — 828 metres of it, opened in 2010, and still unbeaten.
The Burj Khalifa is in downtown Dubai, United Arab Emirates, and has been the world's tallest building since it opened on 4 January 2010. It stands 828 metres tall, was designed by Adrian Smith at Skidmore, Owings & Merrill, cost around US$1.5 billion, and was renamed from Burj Dubai to honour Abu Dhabi's ruler on the day it opened.
A tower Dubai promised
Dubai spent the early 2000s building things that had not been built before, and the Burj Khalifa was the promise at the centre of it. The developer, Emaar Properties, did not set out to build a tall building so much as to build the tallest — a tower whose height was itself the product, designed to put a city with a short history on every skyline in the world at once.
The tower went up in Downtown Dubai, the district built around it, and construction ran from 2004 to 2010. It topped out in January 2009 and opened to the public on 4 January 2010 at 828 metres — more than 300 metres taller than the previous record holder.
From Burj Dubai to Burj Khalifa
For almost its entire construction the tower was called the Burj Dubai: the Tower of Dubai, a name about a city's ambition. That changed on opening day, when it was renamed the Burj Khalifa after Sheikh Khalifa bin Zayed Al Nahyan, President of the United Arab Emirates and ruler of Abu Dhabi.
The reason was practical as much as ceremonial. The tower opened into the global financial crisis, and Dubai — heavily indebted and over-extended — was rescued in part by support from Abu Dhabi. Renaming the world's tallest building after Abu Dhabi's ruler was, in the most literal sense, a monument to the money that had kept the project's home city upright.
Engineering the tallest building on Earth
The design came from Adrian Smith, then at the Chicago firm Skidmore, Owings & Merrill, with Bill Baker leading the structure. Their solution to the desert wind was geometry: a Y-shaped plan with three wings arranged around a central core, so that the tower presents a different, changing profile to the wind at every height rather than a single flat face.
That shape narrowed as it rose, shedding area in steps until it reached the spire — the reason the tower's silhouette reads as a series of shrinking setbacks rather than a slab. The structure is reinforced concrete, not steel, which in Dubai's heat performed better and allowed the tower to be built quickly. The core and the wings brace each other, and the whole thing sits on a deep, pile-supported raft foundation.
The numbers behind the spire
The headline figure is 828 metres, or 2,717 feet. The tower has 163 floors. It was built by a consortium led by Samsung C&T of South Korea with Besix of Belgium and Arabtec of the UAE, for a cost reported at around US$1.5 billion — an extraordinary sum for a single building, and a small one compared with the value of the city's global brand.
The records came in layers: tallest building, tallest freestanding structure, highest occupied floor, highest outdoor observation deck, and the longest elevator travel distance for a service lift. The facade is glass and aluminium, some 24,000 cladding panels, and the tower's angle to the sun limits heat gain in a city where summer temperatures pass 45°C.
A vertical city
The Burj Khalifa is not an office tower with a view. It is a small vertical city: luxury residences on the lower and middle floors, corporate suites above, the Armani Hotel occupying levels within the tower, restaurants and lounges at altitude, and observation decks that have made it one of the most visited buildings in the world.
At the base sits The Dubai Fountain, whose water jets and lights perform nightly in front of the tower, and around it the Downtown Dubai district, with Dubai Mall — one of the largest shopping centres on the planet — directly alongside. The tower was designed to be looked at, but it was also designed to be the reason people crossed the city.
The view from the 148th floor
Visitors go up in two stages. "At the Top" occupies levels 124 and 125, roughly 450 metres up, while "At the Top SKY" on level 148 reaches about 555 metres — high enough that the spire above is still climbing away from you, and high enough that the Gulf fills the western horizon.
From there the logic of the building is clear. It is not the tallest thing in the world because Dubai needed the space; it is the tallest because height itself was the marketing strategy, and the observation deck is where the strategy is sold.
The next challenger
For more than fifteen years no completed building has come close. The tower's only serious rival is the Jeddah Tower in Saudi Arabia, designed to pass one kilometre, which resumed construction and has risen past half the Burj Khalifa's height — but it is still unfinished, and until it tops out the Dubai tower keeps the title.
Meanwhile cities keep planning ever-taller things, and almost none of them get built. That is the Burj Khalifa's real achievement: not just that it is the tallest, but that it was financed, engineered and finished.
Where the Burj Khalifa is now
The Burj Khalifa is in Downtown Dubai, United Arab Emirates, at the coordinates marked on this profile, and it is fully open: residences, hotel, offices, restaurants and the observation decks on levels 124, 125 and 148 all operate as normal. It remains the world's tallest building, the centrepiece of Dubai's tourism pitch, and the anchor of a district built entirely around its shadow.
It is a building that answers a question the world had stopped asking — how tall can we go? — and it also demonstrates the limits of the answer. To beat it, someone must outspend it, and so far, nobody has finished the job.
