65-story building with 1,000 sqm penthouse apartment planned for Toranomon

Long-awaited plans for the Toranomon-Azabudai District in central Tokyo have finally been released. The development, which will be carried out by Mori Building, will include a 65-story mixed-use building that will contain mostly office space, as well as apartments and an international school. Construction is scheduled to start in 2018 with a completion date in 2022.

The 330 meter tall building will be Japan’s tallest building when complete in 2022 and just 2 meters shorter than Tokyo Tower, although it is expected to be overtaken by a 390 meter tall office tower planned for the Otemachi district near Tokyo Station.

The building will have a total floor area of 449,000 square meters (approx. 4.8 million sq ft). In addition to the office space, there will be 80 apartments on the 56th ~ 65th floors of the building. The smallest apartment will be a generously sized two bedroom apartment with a floor area of 125 square meters (1,345 sq ft), while the largest apartment will have a floor area of over 1,000 square meters (10,760 sq ft). This apartment could possibly be the largest apartment ever offered in Japan.
