Jeddah Tower[a] is amegatallskyscraper under construction inJeddah, Saudi Arabia. Located in the north of the city, it is the centrepiece of theJeddah Economic City project.[6] Jeddah Tower is planned to be the first 1-kilometre-tall (1,000 m; 3,300 ft) building and, upon completion, would become the world’stallest building or structure, standing at least 180 metres (590 ft) taller than theBurj Khalifa.[7][8]
The design, created by American architectAdrian Smith, who also designed theBurj Khalifa, incorporates numerous unique structural and aesthetic features. The creator and leader of the project is Saudi Arabian princeAl-Waleed bin Talal,[9] who is the chairman ofKingdom Holding Company (KHC). KHC is a partner in the Jeddah Economic Company (JEC), which was formed in 2009 for the development of Jeddah Tower and City.[10]
Construction progress was halted in January 2018, when building owner JEC stopped structural concrete work. At the time, approximately one third of the tower had been completed. The halt resulted from labor issues with a contractor following the2017–2019 Saudi Arabian purge and theCOVID-19 pandemic. In September 2023, a new request for proposals was issued for completion of the delayed project.[11] After nearly five years of inactivity, development work resumed in 2023.[12] Construction restarted in January 2025, and the building is expected to be completed as early as 2028.[13]
Jeddah Tower's 50-hectare (120-acre) plot, along with surrounding buildings, will be the first of a three-phase Jeddah Economic City development. The three-phase project was proposed for a large area of undeveloped waterfront land with an area of 5.2 square kilometres (2.0 sq mi).[14] The area is located roughly 20 kilometres (12 mi) north of the port city of Jeddah. Jeddah Economic City was designed byHOK Architects,[15] and is estimated to cost at least SR75 billion (US$20 billion) and take around ten years to build.[16]
The development is envisioned to grow into a new district of Jeddah.[17] The second phase of the project will be the infrastructure development needed to support the city, and the third phase has not yet been revealed.[18]
The focal point of the development and Jeddah Tower's primary use will be to house aFour Seasons hotel, Four Seasons short-rental apartments, Class A office space, and luxury condominiums. The tower will also have the world's highestobservation deck.[19] Although the Jeddah Economic City plot is nearly isolated from the current urban core of Jeddah, no land tracts of such size were available closer to the city.[18] Northward is generally considered the direction in which the city will spread in the future.
In May 2008,soil testing in the area cast doubt over whether the proposed location could support a skyscraper of the proposed one-mile (1,600 metres, 5,250 ft) height, andMEED reported that the project had been scaled back, making it "up to 500 metres (1,640 ft) shorter".[20] Work on the foundation was scheduled to begin towards the end of 2012.[21] Statements that construction would soon begin were made starting in 2008. In August 2011, the start of construction was slated as "no later than December".[22] This meant the tower was expected to be completed in 2017, though at that time it was also possible that it could still have been completed by the date the media continued to publish, which was the prior estimate of late 2016.[23] Only if construction had begun promptly and gone smoothly could completion in late 2016 have been achieved.[15]
Reports in 2009 suggested that the project had been put on hold due to the2008 financial crisis and thatBechtel (the initial engineering firm for this project) was "in the process of ending its involvement with the project".[24][25] Kingdom Holding Company quickly criticized the news reports, insisting that the project had not been shelved.[26]
In March 2010,Adrian Smith ofAdrian Smith + Gordon Gill Architecture (AS + GG) was selected as the preliminary architect[27] (though the firm deny involvement in the earlier, mile-high design[28][29]). Later, when the proposal was more serious, they won a design competition between eight leading architectural firms, includingKohn Pedersen Fox, Pickard Chilton, Pelli Clarke Pelli, andFoster + Partners, as well as the firm Smith formerly worked for,Skidmore, Owings and Merrill,[30] which was the final competitor in the competition before AS + GG was chosen.[31] In addition to Burj Khalifa, Adrian Smith has designed several other recent towers; theZifeng Tower inNanjing, China, theTrump International Hotel & Tower in Chicago, and theJin Mao Tower in Shanghai,[32] as well as thePearl River Tower inGuangzhou, China.[33] The four buildings are all among the forty tallest in the world. Furthermore, the Pearl River Tower is a unique tower that was originally designed to use zero net energy by drawing all its needed power fromwind,sunlight, andgeothermal mass,[34] though this design goal was not fully achieved.[35]
In October 2010, the owners (Kingdom Holding Company) signed a development agreement withEmaar Properties PJSC. The final height of the building was questionable, but it was still listed to be over 1 kilometre.[36] Kingdom Holding said construction was progressing.[37][38]
Designs for the foundation were in place by early August 2011 and the contract for thepiling was tendered.[39] On 16 August 2011, Langan International officially announced their involvement and that the foundation and piling had to be uniquely designed to overcome subsurface issues such as softbedrock andporous coral rock, which normally could not support a skyscraper without settling.[40] The foundation is similar to that of the Burj Khalifa, but larger; it is expected to average around 4.5 m (15 ft) deep with a concrete pad of area around 7,500 m2 (81,000 ft2). The concrete must have lowpermeability to keep out corrosivesalt water from the Red Sea. Its depth and size are also considered to be an indicator of what the tower's final height will be.[41] The piles will be up to 200 m (660 ft) deep and the pad over 90 m (300 ft) across, yet the building, which will weigh over 900,000 tonnes (890,000 long tons; 990,000 short tons), is expected to settle. The idea is that it settles evenly enough so that the building does not tip or put undue stress on thesuperstructure. Computer modelling programmes performed tests at the site to confirm that the foundation design would work.[42] A later design for the foundation, to be constructed by Bauer in 2013, calls for 270 bored piles up to 110 m (360 ft) deep, which have to be installed into the difficult ground conditions.[21] Some materials needed for the structure are 500,000 m3 (18,000,000 cu ft) of concrete and 80,000 t (79,000 long tons; 88,000 short tons) of steel.[43]
In March and April 2011, several news agencies reported that the Mile-High Tower design had been approved at that height and that the building would cost almost US$30 billion (SR112.5 billion).[28][29][44] This design was going to be drastically larger than the current design, with a floor area of 3,530,316 m2 (38,000,000 ft2), and would have used futuristic wind-aversion and energy-producing technology for sustainability. It and the surrounding city would have had the ability to accommodate 80,000 residents and one million visitors, according toRIA Novosti.[44]
On 2 August 2011, it was publicly announced by Kingdom Holding, the investment company, that a contract had been signed bySaudi Binladin Group (SBG), that construction was going to start soon, and that the tower was expected to take 63 months to complete.[45][46][47] While the official construction estimate was (at the time) expected to take five years and three months (63 months), others calculated that it will take over seven years, based on the duration of Burj Khalifa's construction.[48]
In early August 2011, theBinladin Group was chosen as the main construction contractor with the signing of an SR4.6 billion (US$1.23 billion) contract,[49] which is less than it cost to build the Burj Khalifa (US$1.5 billion).[50] New renderings were revealed, and on 2 August it was widely reported that the project was a go at the 1,000-metre (3,300 ft) height[A] with a building area of 530,000 square metres (5,704,873 ft2),[B][51][52] and will take 63 months to complete.[53] The announcement of the main construction contract signing caused Kingdom Holding Company's stock to jump 3.2% in one day,[54] in addition to KHC already having reported a 21% rise in second-quarter net profit.[55] Gordon Gill and Adrian Smith were also confirmed as the architect.[56] Thelandscaping contract for the Jeddah Tower was awarded to Landtech Designs, a US-based company, which was tasked with irrigating 3.4 hectares (8.5 acres) of green space, to be collected through rainwater.[57][58]
Financing for the Jeddah Tower was complete by September 2012; Talal Al Maiman, chief executive officer and managing director of Kingdom Real Estate Development Co., said it had taken 20 months to gather all the investors.[59] The next month, Kingdom Holding awarded contracts totalling $98 million, and Subul Development Company paid $66.5 million for some land on the site. The Kingdom Riyadh Land project, a mixed-use commercial and residential development, will generate more than $5.33 billion of total investment and will house up to 75,000 people. The final master plan contract was awarded to Omrania & Associates and Barton Willmore.[60] Bauer, a German Foundations equipment manufacturer and contractor, was awarded a $32 million contract to support the initial phases of construction of the Jeddah Tower, including the installation of 270 bored piles measuring 1.5 and 1.8 metres (4 ft 11 in and 5 ft 11 in) in diameter.[61]
The Jeddah Economic Company (JEC) appointed the joint venture ofEC Harris andMace to manage the project in early 2013.[62][63] The Saudi Water Company also signed a 2.2 billion-riyal ($587 million), 25-year deal with JEC to supply 156,000 cubic metres (5,500,000 cu ft)of treated and drinking water per day.[64]
Construction started on 1 April 2013.[65] The pilings were completed that December,[66] allowing above-ground construction to commence in September 2014.[67]
In late 2017, the owner of Kingdom Holding Co, which owns 33% of the tower, and the chairman of the Saudi Binladen Group, which owns 17% and is the primary contractor, were both arrested as part of the2017 Saudi Arabian purge. Construction of the tower continued,[68] although some senior managers at Kingdom Holding were redirected to other projects.[69] In February 2018, Mounib Hammoud, CEO of Jeddah Economic City, said that construction was continuing and that they hoped to open the tower by 2020.[70] The walls had risen to 248 m (814 ft) by October, with the core reaching 60 storeys;[71] at the end of the year, the reported height was 252 m (827 ft).[72]
Building owner JEC halted structural concrete work in January 2018, with the tower about one-third completed, due to labour issues with a contractor following the Saudi Arabian purge. As a result, work on the tower became stalled (after it reached 63rd floor in 2018).[73] Two months later, Kingdom Holding Company signed a deal withOrange Business Services to provideinformation and communication technology (ICT) infrastructure to Jeddah Tower,[70] and construction resumed moved forward after the delay.[74] Work was also stalled in 2020 due to theCOVID-19 pandemic, which ultimately led to a years-long delay.[75]
In September 2023, the Middle East Economic Digest (MEED) reported thatJeddah Economic City had restarted the project and a request for proposals had been issued for a contract to complete the construction of the tower. Fourteen construction contractors from the region, Europe, and China were given three months to prepare their bids.[76] In May 2024, the architect confirmed that construction would resume, and construction officially restarted in January 2025.[77] Work progressed at a relatively slow rate due to the observation ofRamadan in Saudi Arabia, but soon sped up after the festivities with Jeddah Tower reaching its 66th floor by April 2025.[78] During the restarted construction, a new crane was installed on the core part of the tower in order to accelerate the construction.[79] The Jeddah Tower was estimated to be topped out in 2 years.[80][13] By January 2026, work had reached the 80th floor[81][82] and was progressing so quickly that the Jeddah Tower is expected to reach its 100th floor by March 2026.[83]
The primary designer of Jeddah Tower is Chicago-based architectAdrian Smith ofAdrian Smith + Gordon Gill Architecture (AS + GG),[8] the same architect who designed the Burj Khalifa while atSkidmore, Owings & Merrill (SOM),[37] where he worked for almost 40 years.[34] The development of the tower is being managed byEmaar Properties PJSC.[84]Thornton Tomasetti is the structural engineering firm,[81][82] and Environmental Systems Design, Inc. (ESD)[85] is a part of the AS + GG design team that serves as the building services engineering consultants.[86] The main construction firm,Saudi Binladin Group (SBG), is owned by the family of the lateOsama bin Laden;[87][88] Adrian Smith emphasized the company’s size and experience make it suitable for large projects.[31]
Besix Group (Belgian Six Construct), which constructed the Burj Khalifa, was previously considered for the contract, but did not win, partially because SBG invested in Jeddah Economic Company (JEC),[89] contributing SR1.5 billion (US$400 million) towards the development of the project.[90] Besix admitted in 2010 that they expected Binladin Group to win the contract.[91] Jeddah Economic Company is aclosed joint stock company (PJSC) formed in 2009 as a financial entity for Jeddah Tower and Jeddah Economic City. It is made up primarily of financiers (stakeholders) Kingdom Holding Company (33.35%), Abrar Holding Company (33.35%), which is owned by Samaual Bakhsh and businessman Abdulrahman Hassan Sharbatly (16.67%), as well as SBG (16.63%).[92] JEC's assets have a book value of nearly SR9 billion, broken down between aland bank of over 5,300,000 m2 (57,048,725 ft2) (the Jeddah Economic City plot) with a value of SR7.3 billion that will be used ascollateral to attain bank loans, and SR1.5 billion in cash.[18] Kingdom Holding is aninvestment company founded in 1980 and 95% owned byAl-Waleed bin Talal[93] that has assets valued at over $25 billion, with interests in many major companies such asWalt Disney,PepsiCo,Kodak,Apple,Hewlett-Packard,Motorola,Time Warner,News Corporation, Pinnacle Infotech Solutions, andCitigroup, as well as real estate in London through its Songbird Estates division.[87]
The building has been designed to a height of at least 1,008.2 metres (3,308 ft) (the exact height is being kept private while in development, similar to theBurj Khalifa).[A][53] At about one kilometre,[94] Jeddah Tower would be thetallest building or structure in the world,[7] standing 180 m (591 ft) taller than theBurj Khalifa inDubai, United Arab Emirates.[8]
The Jeddah Tower uses a bearing wall structural system in reinforced concrete based on abuttressed core configuration, refined from the system developed for the Burj Khalifa. The structure consists of a closed triangular central core with intersecting concrete walls radiating outward to form three wings that buttress the core and provide lateral stiffness under wind loading. Unlike many other supertall buildings, the structural concept does not rely on outrigger trusses or perimeter mega-columns, with lateral forces resisted primarily through the integrated wall system.
The concept and its antecedents can be traced to earlier concrete tower forms, including three legged structures such as the CN Tower in Toronto, completed in 1976. As the tower rises, the wings progressively taper, with inclined perimeter walls that contribute to aerodynamic stability and reduced wind induced forces. Above the occupied levels, the structure transitions into a predominantly closed wall spire with a different internal layout.[95][96]
The Jeddah Tower incorporates an auxiliarytuned mass damping system within the spire to control wind-induced motion at extreme elevations. Wind-tunnel testing and sensitivity studies indicated that the main tower structure is robust with respect to adverse wind effects and is predicted to remain within acceptable comfort criteria for occupants without the need for supplemental damping. However, while the spire is uninhabited, predicted wind-induced accelerations increase significantly toward the upper portions of the spire due to the non-linear behavior of the fundamental mode shape, requiring specific mitigation measures.
To address this condition, an auxiliary two-staged damping system was specified to limit motion within the spire only. According to the project description, the system consists of two tuned mass damper units with approximate masses of 870 tonnes and 260 tonnes, positioned at levels 206 (826 m) and 218 (874 m), respectively. The system is designed to reduce wind-induced movements in the spire by approximately 30 percent.[97][98]
Lessons from Burj Khalifa informed Jeddah Tower’s structural design and planning of mechanical, electrical, and plumbing (MEP) systems, while meeting local regulations and internationalbuilding codes.[99][100] Adrian Smith noted that practical considerations are often a greater challenge than structural durability, with the tower’s form primarily based on intended functions.[31]Orange Group is responsible for the building'sinformation and communications systems.[101]ESD provides mechanical, plumbing, electrical, and fire protection engineering,[10] as well as teledata, audio/visual, security, and acoustics systems.[85] Langan International handlesgeotechnical engineering and some ground-level site work includingtransportation engineering and parking,[4] including the proposed 3,000–4,700 car underground garage near the tower.[102][31]
The building will have 57 elevators, including 7 double-deck units, and 8 escalators, all supplied by the Finnish companyKone. It will feature the world's highest observation deck, served by high-speed elevators traveling up to 10 metres per second (36.0 km/h; 22.4 mph) in both directions.[2] The elevator system is designed to limit cable weight for efficiency.[103] Vertical circulation will be organized through threesky lobbies for elevator transfers, so that elevator service is segmented through transfer levels rather than a single continuous run. Elevator efficiency and sky lobbies address vertical transportation challenges, allowing transfers without overloading individual elevators.[31] In addition, a dedicated workmen's lift will serve multiple technical levels within the spire, operating between level 169 (680 m) and level 230 (922 m).[2]
The building will include retail and other amenities to operate as a semi-self-sustaining "vertical city".[104] The estimated construction cost of US$1.23 billion is lower than Burj Khalifa’s US$1.5 billion, partly due to lower labor costs and three-shift construction.[50][105]
The 23 hectares (57 acres) area around the tower will include public space, a shopping mall, and residential and commercial developments, forming the Jeddah Tower Water Front District,[30] with the tower site covering 500,000 m2 (5,381,955 ft2).[106] Like other iconic skyscrapers, the tower is intended to be symbolic and to raise surrounding land values rather than its own profitability.[22] Adrian Smith said the design "evokes a bundle of leaves shooting up from the ground; a burst of new life that heralds more growth all around it."[107] The tower and Jeddah Economic City are designed to be interdependent.[31] Talal Al Maiman, board member of Jeddah Economic Company, said the tower will significantly increase the value of surrounding properties.[106]
The development model follows Burj Khalifa, where surrounding malls, hotels, and condominiums inDowntown Dubai generated the majority of project revenue,[108][106] while the tower itself had minimal profit.[109] In 2011, consultancy EC Harris reported Saudi Arabia is the least expensive Middle Eastern country for construction, cheaper thanBahrain andUnited Arab Emirates.[110] The tower’s proximity toKing Abdulaziz International Airport may affect airspace.[104] Experts noted that buildings over one kilometre, including those approaching two kilometres (6,600 feet), are technically feasible but present practical and sustainability challenges.[111][112]
Saudi Arabia has experienced increased demand in itsreal estate market, accompanied by rising property prices, which some analysts have described as indicative of a potentialreal estate bubble. These trends have been linked to rapid population growth and a limited supply of housing. Demand has also extended to high-end residential developments, including projects such as the Jeddah Tower. In response to housing shortages, the Saudi government announced plans to invest US$67 billion (SR251 billion) in the construction of approximately 500,000 homes nationwide as part of broader economic and social development initiatives.[113] Saudi officials have stated that roughly 900 new housing units per day are required to meet the needs of the growing population, which has nearly quadrupled over the past four decades.[23]
The Jeddah Tower is planned as a central component of the widerJeddah Economic City development. In parallel, multiple infrastructure and urban redevelopment projects have been undertaken or proposed across Saudi Arabia. Among these is the US$7.2 billion (SR27.1 billion) expansion ofKing Abdulaziz International Airport, which is intended to support increased capacity and regional development.[114]
According to a representative fromStandard Chartered, which invested US$75 million in theSaudi Binladin Group, Saudi Arabia is expected to allocate more than US$400 billion (SR1.5 trillion) toward infrastructure projects over several years.[115] Analysis byCitigroup reported that approximately US$220 billion in development spending, representing 36 percent of total construction expenditure in theMiddle East and North Africa, could directly or indirectly affect the Jeddah Tower project.[116] The Jeddah Tower and its surrounding development have also been presented by planners as an example of environmentally conscious construction, incorporating modern technologies aimed at reducing their overallcarbon footprint relative to projected occupancy levels.[117]
Developers have suggested that large-scale landmark developments and the international visibility associated with constructing the world’s tallest building could contribute togentrification and increased foreign interest in the country.[118] Architect Adrian Smith, the tower’s designer, described the project as a symbol of Saudi Arabia’s economic ambitions and technological capabilities.[119] In contrast, Bob Sinn, a principal engineer atThornton Tomasetti, noted that the primary difficulties associated with constructing buildings of extreme height are often related to practical and operational considerations rather than structural feasibility alone.[120]
Talal Al Maiman, a board member of both Kingdom Holding Company and Jeddah Economic Company, stated that the tower is intended to function as both an economic catalyst and a symbolic representation of the kingdom’s position in the global economy.[121] BusinessmanAl-Waleed bin Talal characterized the development as a political and economic statement emphasizing domestic investment priorities.[122]
It is estimated that the Jeddah Tower will have 167 floors, with the total number of levels reaching 252, many of which will not be full slab-separated floors but merely practical vertical subdivisions.[E][31][123][124]

At his Kingdom Holding conglomerate, Prince al-Waleed and his team remain nominally in charge. But the Saudi government demonstrated its new influence in February when it ordered some of his senior managers to leave his biggest new project, Jeddah Tower, slated to be the tallest building in the world at over 3,000 feet high. The government directed them instead to work on construction of Neom, a new, high-tech Saudi city envisioned by Prince Mohammed, said people familiar with the directive, who understood it to be in line with the prince's wishes.
