One Centum's bird's-eye view, layout, and building scale released, transforming the core area of Centum City into 'Quantum Complex'
The high-rise mixed-use development project, 'One Centum' at 1502 Woo-dong, Haeundae District, Busan has officially started.
This project is being carried out under the guidance of Hines, a global real estate development company from the United States, and aims to transform the heart of Centum City, which has been abandoned for 20 years, into a harmonious high-rise mixed-use space with modern office space, residential and commercial facilities.
The development is expected to become a new landmark while revitalizing the local economy.
Undeveloped land in Centum City reborn as a high-rise mixed-use town
'One Centum' is designed as a high-rise building with 6 basement levels and 60 above ground levels, reaching a height of 310.3m. The total area amounts to 182,372.75㎡, and it will incorporate various facilities such as offices, officetels, retail spaces, neighborhood facilities, and sports facilities.
In particular, the officetel will consist of a total of 207 units, with a dedicated area of 40,509.7㎡. With this diverse range of facilities in harmony, One Centum is expected to become an attractive space for many people.
The total project cost is estimated at approximately 1.35 trillion won, and this project is named 'Centum Global Quantum Complex.' This signifies a move beyond simple building development toward establishing a global business hub centered on the quantum computing industry.
Designation of a special architectural zone... regulatory relaxation and administrative support
The city of Busan has designated the One Centum area as a special architectural zone, providing various regulatory relaxations and administrative support. This area is divided into central commercial districts, fire protection zones, district unit planning areas, general industrial complexes, etc., and is included in the basic plan for the Centum City industrial complex.
Previously, Hyundai Department Store and Japan's Sega Sammy Group attempted to develop this site, but the project was halted due to profitability issues and changes in the surrounding environment. However, with Hines’ recent involvement, this previously undeveloped area is emerging as a focal point for Busan's future vision, thus raising expectations for the development potential of the One Centum area.
Building review approved, and environmental impact assessment procedures underway
In February 2025, Busan's Architectural Committee approved the building review for the One Centum project. The subsequent procedures include public display and notification of the environmental impact assessment, resident briefings, pre-disaster impact reviews, building safety impact assessments, and fire performance design reviews. So far, two environmental quality investigations and ecosystem surveys have been completed.
This project qualifies as a large-scale building subject to an environmental impact assessment, exceeding a gross floor area of 100,000㎡, with floors exceeding 50 levels or a height exceeding 200m. Therefore, a thorough review in accordance with relevant laws is being conducted simultaneously. This process is considered an essential step to ensure the project's safety and environmental impact.
The future of Centum, led by One Centum
The 'One Centum' project is expected to play a crucial role in transforming Busan into a global business center, beyond mere real estate development. In particular, it is planned to be developed as a cutting-edge workspace to attract quantum technology and IT, research and development (R&D) companies, which is expected to positively impact the development of related industries and job creation for young people.
Moreover, with commercial and neighborhood facilities being placed together, the local economy is also expected to be revitalized. This will be an important step toward fitting the last puzzle piece of Centum City.
Busan City plans to continue comprehensive reviews and support in various sectors such as environment, safety, transportation, and fire to ensure that this project proceeds smoothly, targeting 2030. Such efforts are expected to further advance Busan and contribute to providing better living environments for residents.
Conclusion
The 'One Centum' project is expected to become an important opportunity to transform the long-stagnant core of Centum City into a key area for global business.
The construction of a 310-meter high mixed-use building and the attraction of advanced industries is expected to create new jobs and invigorate the economy. This provides an opportunity to achieve both urban regeneration and economic development objectives simultaneously.
Once the environmental impact assessment and building permit processes are completed and construction begins, One Centum is likely to establish itself as a true landmark in Haeundae.

Chapter 2 Project Overview
2.1 Background and Purpose of the Project
The project area is located within the general industrial complex of Centum City, which is intended to evolve into a high-tech future city with functions such as knowledge information (IT), media, international business, commerce, residential, tourism entertainment, and exhibition convention, having received an environmental impact assessment consultation on June 9, 1988 (Jahwan 67141-334) and completed construction in June 2007.
Meanwhile, the project area has remained undeveloped since 2001, when Hyundai Department Store was designated as the preferred negotiator, but negotiations did not proceed. In 2015, the Sega Sammy Group was selected as the developer and applied for approval for a tourist hotel project plan, obtaining an environmental impact assessment (September 25, 2015).
However, due to the rapid increase in new hotels being constructed nearby, the project's profitability declined, leading to its abandonment, leaving it untouched for approximately 25 years.
In response, the city of Busan plans to transform the existing site supporting the hotel and tourism MICE industry into a global business facility focused on quantum computing.
This project aims to expand office space necessary for advancing to a global business city, creating jobs through the new mixed-use facility and promoting local economic and urban development.
