Jeddah Tower : Tallest building in the world




Saudi Arabia is racing towards becoming no.1 in the race of having tallest building in the world. Dubai’s iconic 828 m – Burj Khalifa, the world’s tallest building is going to lose its crown. The story of modern skyscrapers is due to reach a new milestone in 2019 or rather, kilometer-stone. The first structure in the world to reach the one-kilometer-high mark (the original design was to be one-mile-high (1.6 km), but the geology of the area was not suitable for that height).

Its Construction started on April 1st, 2013. Piling was completed in December 2013. Above-ground construction commenced in September 2014. The building is expected to finish construction in November 2019 (almost 7 years) and opening by 2020.

Jeddah Tower a.k.a. Kingdom Tower

It will also have the world’s highest observatory and sky terrace.

About Jeddah Tower

Expected to cost $1.23 billion to construct. Jeddah Tower will be a mixed-use building featuring a luxury hotel, office space, serviced apartments, luxury condominiums and have the world’s highest observatory at height of 637.5 m (2,092 ft). The height of the skyscraper will be over 1,000 meters (3,280 feet). Like the Burj Khalifa, the final height of the project is undisclosed. It was first proposed to have 1 mile (1.6 km) height, which was not possible due to the geographical condition. The height of the top floor will be 630 m (2,067 ft)



The skyscraper will have 167 (2 below ground) floors (It will have 252 floors, if we include uninhabitable “floors” in the spire or approximately 89 more floors than the 163-floor Burj Khalifa in Dubai). Another unique feature of the design is a sky terrace, roughly 30 meters (98 feet) in diameter, at floor 157.

Jeddah tower will be the centerpiece and first construction phase of the $20 billion, 17 million-square-foot KINGDOM CITY development in Jeddah, Saudi Arabia, near red sea.

It will have 59 (54 single deck and 5 double deck) elevators. The elevators will not reach the speeds of normal elevators, as the change in air pressure at those altitudes would cause nausea.
Three sky lobbies will prevent any one elevator from having to go all the way to the top, eliminating the need for excessively huge cables.

Jeddah Tower is jointly owned by kingdom holding company, Abraar Holding Company, Abdulrahman Hassan Sharbatly and Saudi Binladin Group.


Adrian Smith + Gordon Gill (AS+GG) design has been selected as the chief architect for the tower. Also, for the first time, architects Gordon Gill and Adrian Smith officially announced their involvement in the project.

“This tower symbolizes the Kingdom as an important global business and cultural leader, and demonstrates the strength and creative vision of its people,” said Mr. Smith.

With subtly asymmetrical massing, the tower evokes as a bundle of leaves shooting up from the ground. It is intended to look like a desert plant having three petals shooting upwards. The sleek, streamlined form of the tower can be interpreted as a reference to the folded fronds of young desert plant growth. The way the fronds sprout upward from the ground as a single form, then start separating from each other at the top, is an analogy of new growth fused with technology. Also as a symbol of Saudi Arabia’s growth and future- A burst of new life that heralds more growth all around it. As well as to add prominence to Jeddah’s status as the gateway into the holy city of Mecca.

The three-petal shape of the tower is designed to reduce ‘wind load’ which increases with height and also it produces an aerodynamic shape that helps reduce structural loading due to wind vortex shedding. Its shape is similar to the Burj Khalifa tower in Dubai, which also has quite a stiff shape. The project will feature a high-performance exterior wall system that will minimize energy consumption by reducing thermal loads. In addition, each of kingdom tower’s three sides features a series of notches that creates pockets of shadow that shield area of the building from the sun and provide outdoor terraces with stunning views of the Jeddah and red sea.

The result is an elegant, cost-efficient and highly constructible design taking advantage of new and innovative thinking about technology, building materials, life-cycle considerations and energy conservation.

“We intend Kingdom Tower to become both an economic engine and a proud symbol of the Kingdom’s economic and cultural stature in the world community,” said Mr. Al Maiman, “Kingdom Tower will be a landmark structure that will greatly increase the value of the hundreds of other properties around it in Kingdom City and indeed throughout North Jeddah.”

The design is both highly technological and distinctly organic. In addition to its status as an architectural landmark and economic symbol, Kingdom Tower will also enjoy great cultural significance.

“We envision Kingdom Tower as a new iconic marker of Jeddah’s historic importance as the traditional gateway to the holy city of Mecca,” Mr. Al Maiman said.

He noted that the southeast leg of Kingdom Tower’s tripedal base is on a direct line with the Kaaba in Mecca, Islam’s holiest site.

Construction details

Its Construction started on April 1st, 2013. Piling was completed in December 2013. Above-ground construction commenced in September 2014. The building is expected to finish construction in November 2019 (almost 7 years) and opening by 2020.

The Binladin Group was chosen as the main construction contractor. The Kingdom Tower will have a building area of 530,000 square meters (5.7 million sq ft). It is expected that the tower will require 500,000 cubic meters of concrete and 80,000 tons of steel.

The tower is expected to weight 9,00,000 tons after completion. The foundation is expected to be around 60 meters (197 ft) deep with a concrete pad of around 7,500 m2 (80,729 sq ft) and the piles are expected to be 200 meters (656 ft) deep.

Construction of the building will rely on cutting-edge technology, including the high-strength reinforced concrete and the pumps used to elevate it to record heights, similar to what was used during Burj Khalifa’s construction.

Kingdom Tower will also be consisting of a car parking lot to service almost 3000-4000 cars.

Unique features

  • The Jeddah tower will be home to the world’s highest observatory, at 637.5m (2,092ft) and will also have the world’s highest sky terrace, at floor 157.
  • The kingdom tower will contain 80,000 tons of steel. Parts of the core will contain concrete that is several meters thick.
  • $587 million water contract is signed for the Kingdom Tower. According to the contract signed, the National Water Company will supply 156,000 cubic meters of water daily for 25 years.
  • The world’s tallest crane will serve the construction of Jeddah Tower. The biggest crane is a custom Liebherr type 357 HC-L, developed by German company Liebherr & Wolffkran. It will be able to lift 18 tons of materials at a speed of 44 meters and can withstand harsh meteorological conditions, especially winds.
  • Jeddah tower will use the world’s fastest elevators. Finnish company Kone will provide elevators that can travel at speeds of over 10 meters per second. . It has 59 elevators and 12 escalators, and five of these elevators will be double decker. The elevator shaft will be 637 meters of length in one shot. It will be the highest, longest, above ground, lift shaft in the world.
  • It has high-tech features. A high-performance exterior wall system, including low-conductivity glass, will minimize energy consumption by reducing thermal loads.
