Kingdom Tower, Jeddah | AS+GG

At over 1,000 meters (3,280 feet) and a total construction area of
530,000 square meters (5.7 million square feet), Kingdom Tower will
be the centerpiece and fi rst construction phase of the $20 billion
Kingdom City development in Jeddah, Saudi Arabia, near the Red
Sea.

Expected to cost $1.2 billion to construct, Kingdom Tower will be a mixed-use building featuring a luxury hotel, offi ce
space, serviced apartments, luxury condominiums and the world’s highest observatory. Kingdom Tower’s height will
be at least 173 meters (568 feet) taller than Burj Khalifa, which was designed by Adrian Smith while at Skidmore,
Owings & Merrill.
AS+GG’s design for Kingdom Tower is both highly technological and distinctly organic. With its slender, subtly
asymmetrical massing, the tower evokes a bundle of leaves shooting up from the ground—a burst of new life that
heralds more growth all around it. This symbolizes the tower as a catalyst for increased development around it.
The sleek, streamlined form of the tower was inspired by 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. While the design is contextual to Saudi Arabia, it also represents an
evolution and a refi nement of an architectural continuum of skyscraper design. The three-petal footprint is ideal for
residential units, and the tapering wings produce an aerodynamic shape that helps reduce structural loading due to
wind vortex shedding. The Kingdom Tower design embraces its architectural pedigree, taking full advantage of the
proven design strategies and technological strategies of its lineage, refi ning and advancing them to achieve new
heights.
The result is an elegant, cost-effi cient and highly constructible design that is at once grounded in built tradition and
aggressively forward-looking, taking advantage of new and innovative thinking about technology, building materials,
life-cycle considerations and energy conservation. For example, 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 create pockets of shadow that shield areas of the building from the sun
and provide outdoor terraces with stunning views of Jeddah and the Red Sea.
The great height of Kingdom Tower necessitates one of the world’s most sophisticated elevator systems. The
Kingdom Tower complex will contain 59 elevators, including 54 single-deck and fi ve double-deck elevators, along
with 12 escalators. Elevators serving the observatory will travel at a rate of 10 meters per second in both directions.
Another unique feature of the design is a sky terrace, roughly 30 meters (98 feet) in diameter, at level 157. It is an
outdoor amenity space intended for use by the penthouse fl oor.
The area surrounding Kingdom Tower is known as the Kingdom Tower Waterfront District. Designed by AS+GG,
the 23-hectare Waterfront District provides a cohesive and pedestrian-friendly setting for the magnifi cent
Kingdom Tower while creating a pleasant neighborhood experience nestled along the Kingdom City lakefront. The
Kingdom Tower Waterfront District encompasses a high-end shopping mall and additional development parcels
that accommodate commercial and high-density residential uses, offi ces, two luxury hotels and high-quality open
spaces, including the central Tower Plaza. A serene waterfront promenade connects Kingdom Tower, the various
development parcels, the open space areas and the mall together. The result is an exciting mixed-use area that
offers a concentrated and comprehensive experience including vibrant shopping, entertainment and open-space
amenities. The Waterfront District also provides an array of connections to other areas within Kingdom City’s overall
master plan, designed by HOK Architects.
The Waterfront District is subdivided into 13 development parcels, the largest of which are the Kingdom Tower
parcel of about 90,000 square meters and the mall parcel of about 65,000 sm. Smaller mixed-use parcels of between
5,000 sm and 10,000 sm are arranged in two development precincts, North and South, each with its own unifying
palette of materials. The parcel sizes vary depending on the density of each site; the larger sites are farther away
from Kingdom Tower, with the smaller sites stepping closer to the tower, creating the effect of an architectural
amphitheater around the structure. Views of Kingdom Tower from throughout the District—including the sensitively
designed 20- to 60-story buildings around the tower—are spectacular. The buildings closest to the tower are of lower
heights, ensuring that the outer buildings also have access to views of Kingdom Tower.

Prince Alwaleed Signs SR4.6Billion Contract for World’s Tallest 1,000 meters Tower
2/8/2011

Chairman of Kingdom Holding Company, HRH Prince Alwaleed Bin Talal Bin Abdulaziz Alsaud, who initiated and has been the driving force behind the decision to build the world’s tallest building in the Kingdom of Saudi Arabia, is pleased to announce on 2nd August 2011, that the contract for construction has been signed and Kingdom Tower, with a height of over 1,000 meters, will begin construction imminently in Jeddah, Saudi Arabia. Kingdom Tower will be the centerpiece and the first construction phase of Kingdom City, Jeddah Economic Company’s (JEC) new urban development of more than 5.3 million square meters of land in the north of Jeddah overlooking the Red Sea and Obhur Creek.

Prince Alwaleed commented: “This project will provide sustainable profits to Kingdom Holding shareholders.”

“The vision of constructing the tallest tower in the world in Jeddah belongs to HRH Prince Alwaleed Bin Talal, who was closely involved in the selection of the scheme currently under design,” said Mr. Talal Al Maiman, Executive Director, Development and Domestic Investments, a board member of Kingdom Holding Company and a board member of Jeddah Economic Company, which was formed in 2009 to develop Kingdom City in Jeddah. “Prince Alwaleed, Mr. Bakhsh, Mr. Sharbatly and I were impressed by the boldness and simplicity of the AS+GG design. Kingdom Tower’s height is remarkable, obviously, but the building’s iconic status will not depend solely on that aspect. Its form is brilliantly sculpted, making it quite simply the most beautiful building in the world of any height.” Mr. Al Maiman added: “The decision of the partners to build the world’s tallest building further demonstrates their belief in investing in this nation.”
Five contractors were invited to offer proposals for the Kingdom Tower and a short list of three firms submitted final offers for the tower construction. The Saudi Bin Laden Group (SBG) whose offer was the most attractive in terms of price, quality and schedule was chosen for the project.
With a total construction area of over 500,000 square meters, the soaring Kingdom Tower will be a mixed-use building featuring a Four Seasons hotel, Four Seasons serviced apartments, first class office space, luxury condominiums and an observatory that will be higher than the world’s current highest observation deck. The overall construction cost of the tower is SR4.6 billion ($1.2 billion) and the overall estimated cost of the entire Kingdom City project is anticipated to be SR75 billion ($20 billion).

“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 partners of JEC are Kingdom Holding Company, Mr. Samaual Bakhsh, Abraar, International Holding Company, prominent Jeddah businessmen Mr. Abdulrahman Hassan Sharbatly and Saudi Bin Laden Group (SBG). The capital of JEC is made up of SR8.8 billion in land value, assets that are SR7.3 billion, plus SR1.5 billion in cash contributed by SBG that further demonstrates their confidence in this extensive project.
“We are confident that upon completion, Kingdom Tower will become one of the world’s great tourist destinations as well as one of the most attractive places to live and work in the region,” Mr. Sharbatly and Mr. Bakhsh expressed in a joint statement. “In the meantime, it will create thousands of jobs, spurring the local economy.”
In addition to its status as an architectural landmark and economic symbol, Kingdom Tower will 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 Ka’ba in Mecca, Islam’s holiest site.

An interdisciplinary team led by Adrian Smith + Gordon Gill Architecture (AS+GG), based in Chicago, created the design of the Kingdom Tower. The team also included building services engineering consultants, Environmental Systems Design and structural engineering consultants, Thornton Tomasetti, engineer of three of the world’s top 10 tallest buildings. Jeddah Economic Company selected the AS+GG scheme after a lengthy competition process in which SOM, Pickard Chilton, Kohn Pedersen Fox, Pelli Clarke Pelli and Foster + Partners also participated.
The AS+GG team’s design for Kingdom Tower has been in process since May 2009. Schematic design is complete and design development is under way. Foundation drawings are complete and the piling for the tower is currently being tendered. AS+GG also designed the master plan for the Kingdom Tower Waterfront District, which surrounds the tower and which will include residential and commercial buildings, a shopping mall, high-quality outdoor spaces and other amenities. The overall Kingdom City master plan is being designed by HOK Architects.
“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, whose experience in super-tall tower design includes Burj Khalifa, Jin Mao Tower in Shanghai, Zifeng Tower at Nanjing Greenland Financial Center in Nanjing, the Trump International Hotel & Tower in Chicago and Pearl River Tower, now in the late stages of construction in Guangzhou, China. “Our vision for Kingdom Tower is one that represents the spirit of Saudi Arabia. It also represents new growth and high-performance technology fused into one powerful iconic form.”
The Kingdom Tower design is both highly technological and distinctly organic. With its slender, subtly asymmetrical massing, the tower evokes a bundle of leaves shooting up from the ground—a burst of new life that heralds more growth all around it.. The tower becomes a catalyst for increased development around it.

The sleek, streamlined form of the tower was inspired by the folded fronds of young desert plant growth, Mr. Gill explained. “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,” he said. “We’re thrilled to be working with His Highness, Jeddah Economic Company and Emaar to help define this path for the Kingdom.”
While AS+GG’s design is contextual to Saudi Arabia, it also represents an evolution and a refinement of an architectural continuum of skyscraper design. The three-petal footprint is ideal for residential units, and the tapering wings produce an aerodynamic shape that helps reduce structural loading due to wind vortex shedding. The Kingdom Tower design embraces its architectural pedigree, taking full advantage of the proven design strategies and technological advances of its lineage and extends those advances to the cutting edge.
The result is an elegant, cost-efficient and highly constructible design that is both grounded in built tradition and aggressively forward-looking, taking advantage of new and innovative thinking about technology, building materials and energy conservation. For example, 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 create pockets of shadow that shield areas of the building from the sun and provide outdoor terraces with stunning views of Jeddah and the Red Sea.
The great height of Kingdom Tower necessitates one of the world’s most sophisticated elevator systems. The Kingdom Tower complex will contain 59 elevators, including 54 single-deck and five double-deck elevators, along with 12 escalators. Elevators serving the observatory will travel at a rate of 10 meters per second in both directions.

After months of rumour and suspicion, AS+GG confirms it is designing a $1.2bn, 1000+m tower in Jeddah

As WAN has suggested over the past few months, supertall building experts Adrian Smith + Gordon Gill are to complete the design for a stunning new tower to anchor the proposed $20bn Kingdom City masterplanning project in Jeddah, Saudi Arabia. The firm carefully quashed internet rumours that they were working on a ‘mile-high’ tower, yet did not deny involvement in the Kingdom Tower scheme. This morning His Royal Highness Prince Alwaleed Bin Talal Bin Abdulaziz Alsaud, nephew of Saudi Arabia’s King Abdullah and chairman of Kingdom Holding Company officially announced AS+GG as design architects of the project to awaiting media.

Reassuringly elegant for a tower of such epic proportions – the completed Kingdom Tower will soar at over 1000m (at least 173m taller than the Burj Khalifa which currently holds the title of the world’s tallest building) with a total construction area of 530,000 sq m – the structure is being touted as a new marker of Jeddah’s importance as a gateway to the city of Mecca and has been directly inspired by the folded fronds of a young desert plant. Adrian Smith details: “With its slender, subtly asymmetrical massing, the tower evokes a bundle of leaves shooting up from the ground – a burst of new life that heralds more growth all around it.”

Smith’s partner Gordon Gill continues: “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 the new growth fused with technology.” The graceful needle is also designed to symbolise the city of Jeddah as an economic power and cultural leader, with a focus on the ‘strength and creative vision of its people’.

Aside from the initial ‘wow-factor’ of the building’s statistics, AS+GG have been applauded for their sensitive design aesthetic. Talal Al Maiman, Executive Director, Development and Domestic Investments, a Board member of Kingdom Holding Company and a board member of JEC commented: “Prince Alwaleed, Mr. Bakhsh, Mr. Sharbatly and I were impressed by the boldness and simplicity of the AS+GG design. Kingdom Tower’s height is remarkable, obviously, but the building’s iconic status will not depend solely on that aspect. Its form is brilliantly sculpted, making it quite simply one of the most beautiful buildings in the world of any height.”

Encased in the new spire’s glimmering façade will be a Four Seasons hotel, Four Seasons serviced apartments, Class A office Space, luxury condominiums and the world’s highest observatory. 59 elevators using the world’s most high-tech systems will be installed to provide ease of access, with 54 single-deck and 5 double-deck systems. The residential aspect has influenced the three-petal footprint of the design with tapering wings introducing an aerodynamic shape to reduce structural loading due to wind vortex shedding. All three sides of the Kingdom Tower sport a series of notches which form specifically engineered areas of shadow designed to fall on the outdoor terraces facing the city and Red Sea.

AS+GG is leading an interdisciplinary design team that also includes building services engineering consultants Environmental Systems Design, Inc. (ESD) and structural engineering consultants Thornton Tomasetti. The developer of Kingdom City, Jeddah Economic Company (JEC), selected the AS+GG scheme after a lengthy competition process in which SOM, Pickard Chilton, Kohn Pedersen Fox, Pelli Clarke Pelli and Foster + Partners also participated.

Saudi Arabia Reveals Plans For Tallest Tower, With Terrace On 157th Floor

The design, by Chicago-based Adrian Smith + Gordon Gill Architecture, pairs radical developments in skyscraper technology with a sleek, tapered aesthetic inspired by the folded fronts of young desert plant growth.

Saudi Arabia is set to shatter the record for the tallest building in the world, with a slender, asymmetrical spire that’ll rise at least 3,280 feet in the air. That’s more than twice the size of the Willis Tower, the tallest building in the United States, and 568 feet taller than theBurj Khalifa, the tallest building in the world.

The $1.2 billion Kingdom Tower will be built in north Jeddah, the major urban center of western Saudi and an historic gateway to Mecca just off the shores of the Red Sea. The building, by Chicago-based Adrian Smith + Gordon Gill Architecture (Smith also designed the Burj Khalifa while at SOM), pairs new developments in skyscraper technology with a sleek, “three-petal” form inspired by the folded fronts 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,” Gill says.

The tower’s got a slick, aerodynamic shape with tapering wings that’ll help slash structural loading caused by wind. A high-performance facade is expected to drastically reduce energy consumption, and notches in each of the skyscraper’s three “petals” will create pockets of shade, shielding occupants from the harsh desert sun and providing outdoor terraces with views of Jeddah and the Red Sea. Kingdom Tower will include a Four Seasons hotel and apartments, luxury condominiums, and Class A offices spread over roughly 3.5-million square feet. It’ll also have a sky terrace on the 157th floor (the 157th floor!) and the highest observatory in the world.

Kingdom Tower is the linchpin of a larger, $20 billion waterfront development venture for Jeddah — part of the Saudi monarchy’s ambitious efforts to diversify its economy beyond crude oil. (Financing for the Kingdom Tower results from a deal between the investment firm of Saudi billionaire Prince Alwaleed bin Talal and theSaudi Binladin Group, a construction conglomerate founded by the father of you know who.) The proposed Kingdom Tower Waterfront District — the master plan of which is also designed by Adrian Smith + Gordon Gill — will include residential and commercial buildings, a shopping mall, outdoor spaces, and other amenities.

Wuhan Greenland Center, Wuhan, China | AS+GG

Adrian Smith + Gordon Gill, Thornton Tomasetti and PositivEnergy Practice to design world’s fourth tallest building

Fast becoming leaders in the design of tall buildings, Adrian Smith + Gordon Gill Architecture have just scooped another major project in China which is destined to become the fourth tallest building in the world when construction completes in approximately five years.

Entitled Wuhan Greenland Center, the 606m pillar will be located on the intersection of the Yangtze and Han Rivers and will comprise around 200,000 sq m of commercial office space, 50,000 sq m of high-end residential accommodation, a 45,000 sq m five-star hotel, and a stunning private member’s club in a 27m-tall penthouse volume.

Adrian Smith and Gordon Gill will work as design architects on the 119-storey scheme, with engineers Thornton Tomasetti and energy services, engineering and consulting company PositivEnergy Practice. Speaking on the decision, Gordon Gill commented: “Wuhan is an exciting and important project for our firm as we continue to advance our ideas about performance-based supertall tower design. We look forward to building on past experience on similar projects, with particular emphasis on the relation of architectural form and performance as they pertain to structural wind loads.”

Work is still being completed on the concept design although construction is due to start this coming summer. The structure’s fluid conical form has been deliberately crafted to minimise the volume of structural material needed in construction, whilst its tapered body, softly rounded corners and domed top have been introduced in order to reduce wind resistance and vortex action that occurs around supertall buildings. The tower’s elongated silhouette rises from a tripod-shaped base, tapering gently to an arched apex of smooth curved glass which works in direct contrast to the textured curtain wall of the main column.
