Ingenhoven Architects unveils plans for two Tokyo towers

The German firm Ingenhoven Architects designed two towers, a lifestyle and an office high-rise, for Tokyo’s Toranomon District.

The Toranomon Hills Residential Tower and Toranomon Hills Business Tower will be part of a project led by Japanese developer Mori Building. OMA designed a separate tower in the project, the mixed-use Toranomon Hills Station Tower that will connect with a new train station.

Designboom reports that at 220 meters, the 122,000-sm residential building will be Tokyo’s tallest residential structure. The 175,000-sm office tower will stand 185 meters tall.

The towers will abut the existing Toranomon Hills Mori Tower.

Ingenhoven stressed green space. Both buildings feature horizontal ledges that will shade the glass façades. Tenants will be able to use landscaped areas like terraces, decks, and rooftop gardens. All the integrated plants and green space will, according to the firm, reduce air pollutants and enhance the microclimate. 

The towers, which will also utilize rainwater harvesting, photovoltaics, and high-efficiency lighting, are expected to be completed by 2019.
