The site is in the middle of Japan-Nagano prefecture. It is located in a rural area, surrounded by rice paddy field. The existing building was storage with office space as a whole for selling machine parts. We started to imagine futuristic shape in constructing to the surrounded rice paddy field. We are planning the architecture on this site to create a mysterious atmosphere as a whole scene, by contrasting the contemporary architecture and then we decided to detach it into two parts as its function. Front side is newly built as a work space and Back side is renovated as storage space those are connected.
