This project is an exterior plan aimed at renewing the traditional dark, closed warehouse image, in conjunction with the transformation of a former 15,000-tsubo former ironworks site in the city center into a logistics warehouse. Therefore, by positively embracing prerequisites such as greening ordinances and construction debris, we aimed to create a “place of relaxation” for employees and “harmony with the townscape,” aiming to create a new image of an urban-type logistics warehouse.
By positively interpreting the greening ordinances in Edogawa Ward that may restrict design, and the construction residue from warehouse construction, we attempted to create zones through the remaining soil and plantings, realizing the creation of a new urban-type logistics warehouse that combines a ‘place of relaxation’ for employees and ‘harmony with the townscape’ for local residents.
By utilizing the remaining soil and undulating around the outer edges, the garden was formed as a place to harmonize the scale with the adjacent warehouse, embankment, and town. Landscaping was intensively applied to the undulations, meeting the standards of the ordinance while strengthening the territorial nature of the “garden.” In the center of the garden, rough stones of a difficult diameter are arranged in a circle, raising the security line and the “space” that serves as the focus of attention.














| Overall plan actively utilizing greening ordinances | Landscape using construction debris | |
| By actively interpreting the ordinance regarding greening in Edogawa Ward, instead of distributing the necessary greenery uniformly, the area was concentrated around the surrounding greenery to form a ‘bay’ in the center. We created a relaxing space with a sense of territory, focusing on the continuity of greenery along the street, the view from the street, and accessibility. | By creating a ‘rain garden’ that collects rainwater step by step without transporting leftover soil from the logistics warehouse off-site, it also includes a place to live, thereby reducing environmental impact and cutting costs. | |

Examination of Precise Garden Stones Using 3D Scanning
By utilizing 3D scanning of garden stones within the premises, where Arai Iron Works has witnessed its history, we conducted design studies down to the millimeter level, achieving arrangement considerations that maximize the individuality of the garden stones and competing with metal objects.

By utilizing over 100 garden stones stored on the premises, the iron symbolizing the old ironworks was layered three-dimensionally and scattered throughout the garden as objects, tables, and benches, while these elements were scattered to blend seamlessly with the terrain, actively promoting the legacy.

The surrounding area is surrounded by lush green hubs such as Nagisa Park and Kazumi Park. The cluster of commercial facilities centered around Ario Kasai was bustling with activity, and people enjoying running and walking could be seen along the greenway. He believed that playing a role in connecting green and human networks is “harmony with the townscape.”
