JEC Tower: World’s New Tallest Building in Saudi Arabia
Saudi Arabia’s World’s new tallest building JEC Tower races toward completion in Saudi Arabia as the ambitious JEC Tower passes the 100-floor milestone and moves steadily toward becoming the first skyscraper to exceed one kilometer in height. The project is now progressing rapidly after years of delays, with completion currently targeted for 2028, making it one of the world’s most significant engineering achievements.
For years, the race to build the world’s tallest skyscraper appeared uncertain after construction on the project stalled for an extended period. Today, however, the story has changed dramatically. Construction crews are once again making visible progress, and the tower is climbing higher almost every month.
The project, officially known as JEC Tower (Jeddah Economic Company Tower) and previously referred to as Jeddah Tower and Kingdom Tower, is once again capturing worldwide attention. Once completed, it will permanently take the title of the world’s tallest building from Dubai’s Burj Khalifa and become the first structure in history to rise beyond the symbolic one-kilometer mark.
A Major Construction Milestone Has Been Reached
The latest construction update marks one of the biggest moments in the project’s history.
According to recent reports, JEC Tower has now reached 102 completed floors, making it one of only a small number of skyscrapers worldwide ever to exceed the 100-floor mark. This milestone reflects the remarkable pace of construction since work resumed after years of interruption.
Only a few months earlier, the tower stood at around 69 floors before construction accelerated significantly. Engineers and project managers have steadily increased the building’s vertical progress, bringing the historic project much closer to its final height.
For architecture enthusiasts and skyscraper followers, crossing the 100-floor threshold is much more than a symbolic achievement. At these heights, every additional floor presents increasingly complex engineering challenges involving wind forces, structural stability, concrete pumping, elevator systems, and construction logistics.
What Is JEC Tower?
Developers are building JEC Tower, a supertall mixed-use skyscraper, in Jeddah, Saudi Arabia, along the Red Sea coast. The tower serves as the centerpiece of the larger Jeddah Economic City development, a master-planned urban district that aims to transform the area into a global destination for business, tourism, luxury living, and investment.
The tower is designed by the internationally renowned architectural firm Adrian Smith + Gordon Gill Architecture (AS+GG). Adrian Smith is also famous for designing the Burj Khalifa, meaning he is responsible for both the current and future tallest buildings on Earth.
Rather than simply breaking a height record, the project aims to create an iconic landmark that represents Saudi Arabia’s growing ambitions in architecture, engineering, tourism, and economic diversification.

Why This Project Is Making Global Headlines?
Skyscrapers have always represented more than just impressive heights. They demonstrate technological capability, economic confidence, and national ambition.
JEC Tower is receiving worldwide attention because it is expected to achieve several historic firsts simultaneously.
Among its most significant milestones are:
- The first building to exceed one kilometer in height.
- The future tallest building in the world.
- One of the largest reinforced-concrete skyscrapers ever constructed.
- Home to what is expected to become the world’s highest observation deck.
- The centerpiece of one of Saudi Arabia’s largest urban developments.
These achievements explain why every major construction update attracts global media coverage.
How Tall Will the Tower Be?
Although the project’s exact final architectural height has not been officially disclosed, developers have consistently confirmed that it will rise well beyond 1,000 meters (0.62 miles).
That means the tower will comfortably surpass the current record holder, the Burj Khalifa, which stands at 828 meters (2,717 feet).
To appreciate the scale, consider these comparisons:
| Landmark | Height |
|---|---|
| Eiffel Tower | 330 m |
| Empire State Building | 443 m |
| One World Trade Center | 541 m |
| Burj Khalifa | 828 m |
| JEC Tower | More than 1,000 m (planned) |
From its highest observation areas, visitors are expected to enjoy views stretching well over 100 kilometers across Jeddah and the Red Sea under favorable weather conditions.
Why Building Beyond One Kilometer Is So Difficult?
Constructing a skyscraper that exceeds one kilometer requires engineering solutions far beyond those used in conventional high-rise buildings.
As a structure becomes taller, it must withstand stronger wind loads, greater structural movement, enormous gravitational forces, and increasingly difficult construction logistics.
Some of the biggest engineering challenges include:
- Pumping concrete hundreds of meters into the air.
- Maintaining structural stability during high winds.
- Designing elevator systems capable of serving extreme heights efficiently.
- Managing thermal expansion caused by intense desert temperatures.
- Ensuring occupant comfort by minimizing building sway.
Engineers involved in the project have adopted a concrete-based structural system that relies on interconnected walls rather than traditional columns and outriggers. This design helps distribute both gravity and wind loads more efficiently while simplifying construction. The tower also rests on a massive 5-meter-thick raft foundation supported by 270 bored piles extending as deep as 105 meters below ground.
More Than a Skyscraper
Although headlines focus on the tower’s height, JEC Tower is intended to function as a complete vertical city.
Once completed, it will include:
- Luxury residences
- Premium office space
- A five-star hotel
- Retail and hospitality facilities
- High-end restaurants
- Conference facilities
- Public viewing areas
- The world’s highest observation deck
This mixed-use approach ensures the building remains active throughout the day while attracting residents, tourists, businesses, and international visitors.
Instead of standing alone, the tower will anchor the much larger Jeddah Economic City development, creating an entirely new urban district around it.
From Years of Delays to Rapid Progress
The journey to becoming the world’s tallest building has not been straightforward.
Construction originally began with enormous expectations, but financial challenges and other project-related issues led to a lengthy pause that left many wondering whether the tower would ever be completed.
Today, those doubts are fading.
Recent construction updates show steady progress, renewed investment, and strong momentum toward the current 2028 completion target. Unlike some other ambitious Saudi megaprojects that have reportedly been scaled back or revised, JEC Tower is continuing to rise and remains one of the country’s flagship developments.
Engineering Behind the World’s Tallest Building JEC Tower
Constructing a building that rises beyond one kilometer requires engineering solutions that go far beyond those used in conventional skyscrapers. Every additional floor increases structural loads, wind pressure, and construction complexity, making JEC Tower one of the most technically demanding projects ever attempted.
To overcome these challenges, engineers have combined advanced structural design, high-strength materials, and sophisticated construction techniques. The result is a tower designed to remain stable, efficient, and safe despite its unprecedented height.
A Shape Designed to Defeat the Wind
One of the greatest threats to any supertall building is wind. At extreme heights, powerful gusts can create vibrations that affect both the structure and the comfort of occupants.
Rather than using a simple rectangular design, JEC Tower features a sleek, tapering form inspired by the leaves of desert plants. As the tower rises, its floor plates gradually reduce in size, disrupting wind patterns and minimizing the formation of strong vortices around the structure.
This aerodynamic design helps:
- Reduce wind pressure on the building.
- Limit structural movement at higher elevations.
- Improve occupant comfort by reducing sway.
- Increase long-term structural efficiency.
The tower’s three-winged layout also distributes forces more evenly, making it one of the most advanced skyscraper designs ever developed.
Massive Foundations for a Massive Structure
A one-kilometer-tall tower requires an equally impressive foundation.
JEC Tower stands on a reinforced concrete raft approximately 5 meters thick, supported by around 270 deep foundation piles extending roughly 105 meters into the ground. These piles transfer the enormous weight of the building to stronger underground layers, helping ensure long-term stability despite the challenging soil conditions near the Red Sea.
The foundation alone represents years of planning, testing, and engineering analysis.
High-Speed Elevators and Smart Building Systems
Moving thousands of people through more than 150 floors presents another major challenge.
When completed, the tower is expected to feature approximately 59 elevators, including ultra-high-speed lifts capable of transporting passengers efficiently between different sections of the building.
Other advanced systems include:
- Intelligent building management technology.
- Energy-efficient climate control.
- Water-saving infrastructure.
- Modern fire safety and emergency evacuation systems.
- Advanced security and access controls.
These technologies are designed to create a comfortable experience while improving operational efficiency.
What Will Be Inside JEC Tower?
Although its height attracts the most attention, JEC Tower is designed as a fully integrated mixed-use development rather than simply an observation tower.
Visitors, residents, business professionals, and tourists will all use different sections of the building.

Observation Deck
Perhaps the building’s biggest attraction will be its observation deck.
Expected to become the highest observation deck in the world, it will provide visitors with breathtaking views stretching across Jeddah, the Red Sea coastline, and surrounding landscapes on clear days.
JEC Tower vs Burj Khalifa
As JEC Tower approaches completion, comparisons with Burj Khalifa have become increasingly common.
| Feature | JEC Tower | Burj Khalifa |
|---|---|---|
| Country | Saudi Arabia | United Arab Emirates |
| City | Jeddah | Dubai |
| Planned Height | Over 1,000 m | 828 m |
| Floors | 157+ | 163 |
| Architect | Adrian Smith + Gordon Gill | Adrian Smith (SOM) |
| Completion Target | 2028 | Completed in 2010 |
| Observation Deck | Planned world’s highest | World’s highest currently in operation |
Although Burj Khalifa will likely retain more occupied floors, JEC Tower will surpass it in overall architectural height by a considerable margin.
Interestingly, architect Adrian Smith played a leading role in designing both skyscrapers, making this project a remarkable continuation of his work in pushing the limits of modern architecture.
