Approved under the Single Housing Complex Certification and Comprehensive Design System, this mixed-use development on a site 2.7 hectare comprises four buildings: a high-rise office tower, residential tower, Swedish Embassy, and TV Tokyo Headquarters. The wide throughfare “Shiroyama Greenway” on the southern site forms a lush pedestrian network connecting Kamiya-cho Station to Roppongi 1-chome Station. Comfortable pedestrian spaces linking Shiroyama-dori to a ridge-trail , a plaza centered on a circular staircase, and a playground are placed as public open spaces, enhance the comfort of the community. Beyond public space development, the project was designed with a district heating system in order to contribute not only disaster preparedness but also urban environmental improvement.
