複数フロアにまたがるオフィスでフロア間の分断を防ぎ交流を活性化させる内階段。部門間の交流を特に重視するispaceでは、新本社オフィスの象徴として空間のコアに設置した。6階=SPACE(宇宙)、7階=EARTH(地球)とテーマ設定された2つのフロアを、コーポレートカラーの階段=ispaceがつなぐという比喩表現にもなっている。

User's Voice

iShop Co., Ltd.
Junpei Nozaki, Director, CFO and Executive in charge of Business Operations

The phrase "energy flows" perfectly describes this office. Whether on the stairs or in the work area, you can constantly sense the movement of the employees, and it raises expectations that better things will be created in this office. Guests who visit from both within Japan and overseas are also impressed, and it made me realize that it is possible to move people's hearts in an office. On the other hand, there is also the pressure to deliver a return on investment, but I see that as part of what makes this a living office.
When selecting a partner for this project, our top priority was whether they genuinely cared about our company's needs. While many proposals prioritized design, Itoki took the time to understand our work style and stayed with us until the end, even when we repeatedly requested design changes. I believe that working together as one team was the greatest achievement of this project.

​

ispace's headquarters relocation project is part of their vision to expand humanity's living space into outer space.
Amidst the tension of being pressured to achieve the yet-to-be-seen results of space development, it was necessary to unite ispace's talented personnel, who were gathered from all over the world, by consolidating their offices.
Physically, the space aims to integrate departments through central staircases connecting floors, while psychologically, it meticulously translates the vision and business into the physical environment. We aimed to create a space that transcends the office, where colleagues who share the ambition to "create the next economic zone in space" are strongly connected like a family, facing the same direction, and united in their will as a single living organism.
Being able to contribute through spatial design to such a passionate team challenging the frontiers of humankind was an incredibly fortunate experience as a designer.
