115.8平方米的场地位于一条繁忙的商业街旁，设计的主要任务是对一栋既有的钢结构仓库/办公建筑进行重建。由于面向宽阔的街道，该场地有着便于货物装卸的优势，其位于街角的地理位置也使其得以从周围环境中突显出来。另一方面，场地的劣势在于，繁忙的交通在白天会产生持续的噪音，且路面的硬度也有所欠缺。

The 115.8 m2 site sits along a busy industrial street, and the program was to rebuild the existing steel structured warehouse / office building. Being adjacent to a wide street, the advantages of this site were accessibility with an ease of loading and unloading, quantity and size wise, the merchandize they deal in and the site also being a corner site, the building would stand out from the surroundings. On the other hand, the disadvantages were the continuous noise during the day, together with the tremors caused by heavy traffic and also the extremely week ground strength.

委托方是一家以销售螺栓和螺母等建材为主业的公司，他们希望新总部能够兼备仓库、展厅和办公室的功能，并且拥有足够有趣和引人注目的建筑特征。然而项目的预算却十分有限，仅能达到普通混凝土建筑建造预算的60%（约24-25万日元/平方米）。在充分分析了客户需求和成本预算之后，建筑师与结构工程师和施工方共同进行了对具体施工方案的研究。

The clients’ company is a moderate size retailer handling a vast range of nuts and bolts together with other architectural materials. They requested the new headquarters to have the function of a warehouse, showroom and an office; and to be an interesting, eye-catching piece of architecture. However, the budget was extremely limited, at about 60% (about 240-250K yen per square meter) of an average concrete building. Through analyzing the clients’ requests thoroughly and with the minimum possible cost and the image of the final structure in mind, I began studying the possibilities together with my fellow structural engineer and contractor.
