Landscape for office environments 8/9


□ I-Garden at Chiyoda Iida-town

There is a highly narrative landscape work completed in 2003, same year as Roppongi Hills started operating. I-Garden at Chiyoda Iida-town is the project of “environmentally enhanced approach on the high-rise compound city” conceptualized to harmonize “Working, Living, Gathering, and Resting” redeveloping about 5 ha of warehouses and freight yards belonging to Japan Railway Company. Landowners and 10 other companies concerned have established I-Garden Air Management Council in order to start up making the community.

Tatsuya Hiraga (currently work at Landscape Plus) from Nikken was in charge for the landscape design. Nikken was also the member of the council to discuss again and again about the space they could utilize. The council would continue to involve with the maintenance and management, and that would be ideal setup for landscape space.

The concept was actualization of “History Line, Green Line, and Water Line” that represent spaces based on narrative landscape.

“History Line” can be found along the garden path, the recaptured stonewall referred to the revetment used for daimyo residence used to stand at the project site back in the Edo period, as well as the railroad track symbolized as the former railhead of Kobu Railway during the Meiji period. Also, two straight lights imitating the railroad track are beamed up to the night sky to present the continuity to the future.  

“Green Line” takes a part of the ecological corridor creating spaces full of nature in conjunction with nearby greenery of Koishikawa Korakuen garden and the Imperial Palace.

“Water Line” embalms richness in water sources, which are Kanda River, Nihonbashi River, and the outer moat of the Imperial Palace, surrounding the site. Water sources tightly connected to the daily life produce a sense of changing in lights and seasons as built water-related facilities enhance communication among people.

The project sophisticatedly combined two significant elements in order to build up landscape design. One is, in the neighborly network, to suggest an active role for urban problems to solve as uniting neighborhood by strengthen the natural environment, which expanding not only matters of the design for the project site. Another is, by carefully reading the content in its culture and history, to create a story abundant with narrative spaces and the sequence. Those gimmicks not to be realize at a glance are effective methods permanently rooting the landscape design on the project site, and that would be great example for forthcoming planning.
