Jeddah Tower — The Race to Build the World's First 1,000-Meter Skyscraper
In-depth investor analysis of Jeddah Tower (formerly Kingdom Tower), the $1.4 billion skyscraper designed to exceed 1,000 meters and become the world's tallest building. Explore the engineering, Kingdom Holding's role, construction status, and the investment case for Jeddah Economic City.
Jeddah Tower — The Race to Build the World’s First 1,000-Meter Skyscraper
Jeddah Tower is the building that would redefine what is physically possible in vertical construction. Designed to surpass 1,000 meters (3,281 feet) upon completion, Jeddah Tower — formerly known as Kingdom Tower — would eclipse Dubai’s Burj Khalifa (828 meters) by a margin of over 170 meters, claiming the title of the world’s tallest building by a decisive margin. Developed by the Jeddah Economic Company, a subsidiary of Kingdom Holding Company controlled by Prince Alwaleed bin Talal, the tower is the centerpiece of Jeddah Economic City, a 5.3-million-square-meter mixed-use development on the Red Sea coast north of Jeddah. With a tower budget of approximately $1.4 billion and a total district investment of $20 billion, Jeddah Tower represents one of the most audacious engineering and investment propositions in the global real estate market.
The Ambition — Breaking the 1,000-Meter Barrier
The race to build the world’s tallest building has been a competitive arena for over a century — from the Chrysler Building and Empire State Building in 1930s New York to the Petronas Towers in 1990s Kuala Lumpur to the Burj Khalifa in 2010 Dubai. Each record-breaker represented not just an engineering achievement but a statement of economic ambition by its host city and nation.
Jeddah Tower’s significance extends beyond height. It would be the first human-made structure to breach the one-kilometer mark — a psychological and engineering milestone comparable to the four-minute mile or the sound barrier. The 1,000-meter threshold has been discussed in architectural circles for decades as the next frontier of vertical construction, and Jeddah Tower was designed specifically to claim that frontier.
The tower is designed by Adrian Smith + Gordon Gill Architecture (AS+GG), the firm whose principal, Adrian Smith, also designed the Burj Khalifa during his tenure at Skidmore, Owings & Merrill. Smith’s experience with the Burj Khalifa directly informed Jeddah Tower’s design — lessons learned at 828 meters were applied to solve the additional challenges posed by 1,000 meters.
Engineering and Design
Structural System
Jeddah Tower uses a bundled-tube structural system with a tripod base — three wing-like elements converging at a central core, with the wings stepping back at intervals as the tower rises. This configuration provides structural stability against wind loads (the dominant engineering challenge at this height), distributes gravitational loads efficiently to the foundation, and creates a tapering silhouette that reduces the wind-sail area at upper levels.
The structural system must resist wind speeds of up to 200 kilometers per hour at the tower’s peak height — where atmospheric conditions differ significantly from ground level. Wind-tunnel testing conducted over thousands of hours at specialized facilities in Canada and elsewhere informed the final geometry, with the stepping and asymmetry of the wings disrupting vortex shedding (the phenomenon that causes buildings to oscillate in steady wind).

Foundation Engineering
Jeddah Tower’s foundation is among the most demanding ever constructed. The site’s geology — coastal sedimentary layers above deep bedrock — required drilled piles extending over 105 meters to reach stable bearing strata. The pile system distributes the tower’s enormous gravitational load (hundreds of thousands of tonnes) across the bedrock surface, with redundancy built into the system to accommodate differential settlement.
The foundation concrete pour was one of the largest continuous pours in construction history, using specialized high-performance concrete mixes designed for the site’s specific conditions — including resistance to the chloride-rich groundwater present in coastal Saudi Arabia.
Vertical Transportation
Moving people efficiently through a 1,000-meter building is an engineering challenge in itself. Jeddah Tower uses 59 elevators, including double-deck configurations that serve two floors simultaneously, reducing the number of elevator shafts required and preserving leasable floor area. Sky lobbies at intervals along the tower’s height serve as transfer points, where passengers switch from express elevators (traveling from ground to sky lobby) to local elevators serving individual floor groups.
The elevator system was designed by a consortium led by Kone, with cab speeds of up to 10 meters per second — fast enough to travel from ground to the observation deck in approximately two minutes, but slow enough to avoid passenger discomfort from pressure changes.
Program and Uses
Jeddah Tower is a mixed-use building incorporating five primary functions.
Luxury Hotel
The lower floors house a Four Seasons hotel — the brand’s flagship Saudi Arabian property — with approximately 200 rooms and suites. The hotel occupies premium lower-floor space where the building’s footprint is largest, providing generous floor plates for ballrooms, restaurants, spa facilities, and public areas.
Residential
Branded residences occupy floors above the hotel, offering for-sale condominiums with Four Seasons services. The residential program includes a range of unit sizes from one-bedroom apartments to multi-floor penthouses, with prices reflecting the building’s record-breaking status and Red Sea views.
Office Space
Class A office space occupies the middle floors, targeting multinational corporations, financial institutions, and professional-services firms seeking a prestigious Jeddah address. The office floors offer column-free floor plates, floor-to-ceiling glazing, and access to the building’s shared amenities.
Observatory
The world’s highest occupied floor — an observation deck at approximately 660 meters — provides panoramic views of the Red Sea coastline, Jeddah’s urban landscape, and the Hejazi mountain range. The observatory is designed as a premium ticketed attraction, with projections of 500,000 to 1 million annual visitors generating substantial ancillary revenue.
Sky Terrace
An outdoor terrace — the highest open-air platform on any building in the world — provides an unparalleled experiential attraction. The terrace is designed with safety barriers, wind-management systems, and controlled access, offering visitors the experience of standing outdoors at a height previously accessible only to aircraft.
| Tower Program | Floor Range | Area (sqm) |
|---|---|---|
| Four Seasons Hotel | Floors 1–20 | 45,000 |
| Serviced Residences | Floors 21–60 | 65,000 |
| Office Space | Floors 61–110 | 75,000 |
| Observatory | Floor ~157 | 3,000 |
| Sky Terrace | Floor ~160 | 1,500 |
| Mechanical/Service | Multiple floors | 54,000 |
| Total | 167+ floors | 243,866 |
Jeddah Economic City — The District Context
Jeddah Tower is not a standalone building — it is the anchor of Jeddah Economic City (JEC), a 5.3-million-square-meter mixed-use district on the Red Sea coast approximately 20 kilometers north of Jeddah’s city center. JEC is designed as an integrated urban district featuring residential towers, commercial offices, retail malls, hotels, a waterfront promenade, cultural facilities, and public parks.
| JEC District Metrics | Value |
|---|---|
| Total Site Area | 5.3 million sqm |
| Total Built-Up Area | 12+ million sqm |
| Residential Units | 35,000+ |
| Hotel Rooms (District) | 5,000+ |
| Retail Space | 500,000+ sqm |
| Office Space | 1+ million sqm |
| Total District Investment | $20 billion |
| Target Population | 80,000+ residents |
| Waterfront Length | 3+ km |
The district’s master plan positions Jeddah Tower as the visual and functional centerpiece — visible from throughout Jeddah and the Red Sea, serving as both a landmark and an anchor tenant generator that attracts development investment to the surrounding district. The model mirrors Dubai’s approach with the Burj Khalifa and Downtown Dubai — where the world’s tallest building catalyzed the development of an entire district that now generates billions in annual revenue.
Investment and Financial Architecture
| Financial Metric | Value |
|---|---|
| Tower Construction Cost | $1.4 billion (estimated) |
| Total District Investment | $20 billion |
| Primary Developer | Jeddah Economic Company (Kingdom Holding subsidiary) |
| Principal Investor | Prince Alwaleed bin Talal / Kingdom Holding |
| Construction Financing | Equity + project finance |
| Hotel Revenue (Stabilized) | $100–150 million annually |
| Residential Revenue (Sales) | $500–800 million |
| Office Lease Revenue (Stabilized) | $50–100 million annually |

Kingdom Holding Company, Prince Alwaleed bin Talal’s investment vehicle, is the controlling shareholder of the Jeddah Economic Company. The project has also attracted co-investors from within the Saudi private sector. Financing has been structured through a combination of equity contributions and project-finance debt from regional and international banks.
Construction Status and Timeline
Jeddah Tower’s construction history is marked by both progress and delays. Foundation work and structural construction advanced significantly before the project experienced a period of slowdown due to a combination of factors — including the detention of Prince Alwaleed bin Talal during the 2017 Saudi anti-corruption campaign, contractor disputes, and funding-pace adjustments.
| Construction Milestone | Status / Date |
|---|---|
| Design Completion | 2013 |
| Foundation Works | Completed |
| Core and Structure (To ~65 floors) | Completed |
| Construction Slowdown | 2018–2020 |
| Construction Restart Efforts | 2020 onward |
| New Contractor Selection | Ongoing evaluation |
| Structural Completion (Projected) | TBD |
| Tower Opening (Projected) | TBD |
| Current Height Reached | ~300 meters (~65 floors) |
As of 2026, the tower stands at approximately 300 meters — roughly one-third of its final height — with the structural core, lower-floor concrete work, and significant underground infrastructure complete. The project has cycled through discussions about construction restart, contractor reappointment, and funding recapitalization. The Kingdom Holding Company has reiterated its commitment to completing the tower, and various reports have indicated progress toward resuming full-scale construction.
The construction restart is one of the most closely watched developments in global real estate. The foundation is in place. The lower structure is built. The engineering is proven. The remaining challenge is mobilizing the capital, contractor capacity, and project-management infrastructure to complete the upper 700 meters of the structure.
Engineering Challenges of Extreme Height
Building beyond 1,000 meters introduces engineering challenges that do not exist at lower heights.
Concrete pumping. Delivering concrete to formwork at 1,000 meters requires pump pressures that test the limits of current technology. The Burj Khalifa set records by pumping concrete to 606 meters; Jeddah Tower must exceed that by nearly 400 meters. Specialized high-performance concrete mixes — with carefully controlled viscosity, setting time, and strength characteristics — are required to maintain pumpability over this distance.
Wind engineering. Wind speeds and turbulence at 1,000 meters are significantly greater than at ground level. The tower’s structural system must resist not only steady-state wind loads but dynamic oscillation caused by vortex shedding. Tuned mass dampers — massive counterweights near the top of the building that swing counter to building motion — are incorporated to maintain occupant comfort.
Elevator technology. Conventional elevator systems face limitations at extreme heights — cable weight becomes prohibitive for single-run elevators above 500 meters. Jeddah Tower addresses this through the sky-lobby transfer system and by using carbon-fiber or aramid-fiber elevator ropes that are significantly lighter than steel cables.
Fire safety. Evacuating a 167-floor building requires fire-engineered solutions that go beyond code minimums. Pressurized refuge floors at regular intervals provide safe waiting areas for occupants during phased evacuation. Fire-resistant structural elements maintain integrity for extended durations. Dedicated firefighting elevators provide rapid access for emergency responders.
Temperature and pressure. Air temperature drops approximately 6.5 degrees Celsius per 1,000 meters of altitude gain. At Jeddah Tower’s peak, exterior temperatures are 6 to 7 degrees cooler than at ground level — significant for facade engineering and HVAC design. Air pressure is approximately 12 percent lower at 1,000 meters than at sea level, affecting elevator-cabin pressurization, human comfort, and mechanical systems.
Competitive Landscape
Jeddah Tower exists in a competitive landscape of super-tall buildings vying for records and prestige.
| Building | Location | Height | Status |
|---|---|---|---|
| Burj Khalifa | Dubai, UAE | 828 m | Completed (2010) |
| Jeddah Tower | Jeddah, KSA | 1,000+ m | Under construction (paused) |
| Merdeka 118 | Kuala Lumpur, Malaysia | 678 m | Completed (2023) |
| Shanghai Tower | Shanghai, China | 632 m | Completed (2015) |
| Abraj Al-Bait Clock Tower | Mecca, KSA | 601 m | Completed (2012) |
No other building currently under construction or announced targets the 1,000-meter threshold. If Jeddah Tower is completed, it would hold the world’s-tallest title by a margin that would be difficult to challenge for years or decades — the engineering and financial barriers to exceeding 1,000 meters are substantial.
Risk Factors
Construction restart uncertainty is the most immediate risk. The project has been in a slowdown period, and while the developer has expressed commitment to completion, the timeline and contractor arrangements remain under development. Investors should monitor contractor-appointment announcements and construction-activity reports.
Funding requirements for the remaining construction are substantial — several hundred million dollars at minimum to complete the structure, with additional investment required for fit-out, systems installation, and commissioning. The funding plan must be secured before full-scale construction resumes.
Market conditions in Jeddah’s real estate market will affect residential sales, office leasing, and hotel operating performance. The tower’s premium positioning commands premium prices, but the buyer and tenant pool at this price point is finite.
Completion timeline is uncertain. Super-tall construction is inherently unpredictable, with weather, supply-chain disruptions, and technical challenges all capable of extending timelines. Investors should plan for a multi-year construction period from restart to completion.
Operational complexity — operating the world’s tallest building requires specialized facility management, with unique maintenance challenges (facade cleaning at 1,000 meters, elevator maintenance, structural monitoring) that are not encountered in conventional buildings.

Conclusion
Jeddah Tower is the unfinished symphony of Saudi Arabia’s giga-project portfolio. The foundation is set. The lower structure stands at 300 meters. The engineering has been validated by the world’s foremost super-tall specialists. The Four Seasons brand is committed. The observation deck at 660 meters would be the highest in the world. The question is not whether it can be built — the engineering confirms that it can — but whether the construction will resume at full pace and deliver the world’s first kilometer-tall building.
For investors, Jeddah Tower presents a unique risk-reward profile. The downside risk is construction delay or further slowdown. The upside is participation in one of the most iconic buildings ever conceived — a structure that would define Jeddah’s skyline, generate billions in district-level economic activity, and hold a record that may stand for a generation. The tower is one-third built. The foundation is the hardest part, and it is done. The remaining 700 meters are engineering, concrete, steel, and glass — and the will to build. That will, backed by Kingdom Holding and the broader Saudi ambition, remains the project’s most important asset. Jeddah Tower is waiting to rise. The question is when, not whether.
