ARK Hills Sengokuyama Mori Tower

アークヒルズ 仙石山森タワー

Safe and comfortable Vertical Garden City
ARK Hills Sengokuyama Mori Tower, completed in August 2012 as a new symbol of the ARK Hills area, comprises a 47-story high-rise building and an 8-floor residential building. The complex, while driving local development, has also helped to maintain the area’s rich international and cultural heritage. This safe and comfortable building in a neighborhood that is expected to remain relevant well into the future, has seen its convenience greatly enhanced by the launch of the adjacent Azabudai Hills complex by Mori Building and others in 2023.

Conceptコンセプト

Based on the concept of "a life surrounded by nature in the heart of the city," we are aiming to build an appealing urban area that is very cosmopolitan and has abundant culture. It will combine residential, retail, and business functions to a high standard. The development will be in harmony with other developments in the vicinity, ensure reasonable and sound land use, improve disaster prevention capability, and advance the development of the city infrastructure. 

History開発経緯

This redevelopment project covers approximately 2.0 hectares of land located extremely close to Kamiyacho Station on the Tokyo Subway Hibiya Line and Roppongi 1-chome Station on the Namboku Line. 
Many embassies and hotels are located nearby, making it an area with a strong international flavor, and it is being developed through category 1 urban redevelopment projects such as ARK Hills, Izumi Garden, etc. Moreover the "Loop Road No. 2, vicinity of Shimbashi, Akasaka, and Roppongi" area, which includes the site of this development, has been designated an urgent urban renewal area. 

Development of public facilities is to include widening of the ward road on the western side of the site by 12 meters from the opposite bank, and the building of two new ward roads, 9 meters and 6 meters wide, around the perimeter of the site. We will also develop public spaces inside the site itself, an approximately 3,000m² space on the west side and an approximately 1,000m² space on the south side, and develop new pedestrian walkways and green areas. There is a height difference of approximately 10 meters between the existing residential areas on the west side and east side of the development site, but this project will help to improve the convenience of the area by installing escalators and elevators in the walkways.

Other measures have also been taken to reduce the environmental load, such as using Low-E double windows that reduce the heat entering the building through the windows.
