Developer Mori Building has announced a large-scale redevelopment project involving the construction of three towers in Japan.
The scheme aims to transform Tokyo’s Toranomon Hills area into a global business hub.
The project involves three new mixed-use skyscrapers – tentatively called Toranomon Hills Business Tower, Toranomon Hills Residential Tower and Toranomon Hills Station Tower – that will be built around the existing Toranomon Hills tower which was opened in June 2014.
When completed, the complex will cover around 7.5ha, including the four towers, new transport stations, roads and green space. The development will also house a new subway station and a new bus rapid transit station that will connect central Tokyo and the bay area.
Toranomon Hills project
“The city and its people need to constantly evolve in order to bolster the city’s power to attract creative individuals and enterprises from around the world,” said Mori Building CEO Shingo Tsuji. “We believe that Toranomon Hills complex will continue to catalyse economic, cultural and environmental changes, establishing the area as a hub for international business that will enliven and strengthen Tokyo as a whole.
“We believe that people have the power to change the city. Based on our unique urban design concept of vertical garden cities, which makes intelligent use of ultra-high-rise structures and underground space to enhance infrastructure efficiency and integrate diverse urban functions, we seek to reshape Toranomon Hills into not only a place for business, but also as a community that connects and nurtures diverse people gathered here.”
Toranomon Hills Business Tower
Designed by Ingenhoven Architects, the steel framed structure will generate some 94,000m2 of office space by 2019. The 36-floor tower will house the Innovation Center, offering office space and seminar venues.
The tower will house the new BRT station connecting central Tokyo, the bay area and various venues for Tokyo 2020 Olympic and Paralympic Games, as well as a new bus terminal that will connect Toranomon to Tokyo’s international airports.
Construction is expected to start in 2016.
Toranomon Hills Residential Tower
Also designed by Ingenhoven Architects, the reinforced concrete structure is expected to supply 600 residential units by 2019, bringing the total number in the Toranomon Hills complex to about 800.
Construction of the 56-floor tower is expected to start this year.
Toranomon Hills Station Tower
Designed by architectural firm OMA, Toranomon Hills Station Tower will combine a multi-use high-rise tower with a new subway station. The tower will incorporate the new Hibiya Line subway station, scheduled to begin partial service in 2020, and an elevated open deck with green space connecting the tower to the rest of the complex via the existing Toranomon Hills building.
The specifications for Toranomon Hills Station Tower are still being finalised. Services are scheduled to start before Tokyo 2020, but final construction is unlikely to be complete until 2022.
