Tokyo’s urban jungle is about to become a whole lot greener. Dutch firm ingenhoven architects unveiled designs for the Toranomon Project, a mixed-use development draped with greenery that, once complete, will boast the city’s highest residential building at approximately 220 meters tall. Designed to flank the existing Toranomon Hills Mori Tower on two sides, the green-roofed buildings will include a variety of environmentally friendly technologies, from solar panels to gray water recycling.

The new buildings will feature horizontal ledges to provide solar shading and to maintain a shared architectural vocabulary. OMA has also designed the Toranomon Hills Station Tower, another new building that will join the Toranomon Hills Business and Residential Towers. Together, the Toranomon Hills complex will cover an area of around 7.5 hectares and include integrated transportation spaces—including a new subway station on the Hibiya Line—and green space.

“The result will be an international hub for businesses, residents and visitors alike, based on ingenhoven architects and Mori Building’s shared urban vision of the “vertical garden city,” write the architects. “Planting on the rooftops helps reduce the urban heat island effect while also enhancing the buildings’ appearance when seen from above.” Fully glazed facades optimize natural daylight and open up to landscaped terraces and outdoor decks on multiple levels. The addition of lush plantings also reduces air pollutants and improves the microclimate.

The Toranomon Project is expected to achieve a CASBEE Class ’S’ rating and will include green technologies such as a cogeneration system, gray water recycling, high-performance glazing, rainwater harvesting, photovoltaics, and high-efficiency lighting and mechanical equipment. The project is slated for completion in 2019.
