Toranomon Hills Mori Tower

“The Loop Road No.2” is a new arterial highway which connects the center area of Tokyo with the waterfront area, and “Toranomon Hills” is a pioneering business which integrally consolidates arterial highway and architecture as a facility, which includes an underground tunnel of “The Loop Road No.2”in its basement, utilizing a system of the highway construction and buildings in the same space for urban redevelopment projects.

“Toranomon Hills” has a strong, characteristic silhouette which is unprecedented in Japanese skyscrapers, downsizing its voluminousness to bend the exterior wall since it is extremely massive compared to other surrounding buildings, and its obliquely cooped skyline is easily identified from a long distance as a wide-area recycling landmark.

Also, our design creates a large-scale vacant lot, consolidating complex functionalities such as offices, stores, conferences, residences, hotels into one skyscraper, and creates a new urban space which supplies both enrichment and bustle, strengthening the linkage with surrounding areas attributed to the green square and the stepped garden to avoid dividing the area by the arterial highway.
