Sansan公司自2010年起在德島縣的神山市成立了地方辦公室，稱為“神山研究室”。其所在場地分佈著三座有著70至100年曆史的建築：主屋OMOYA、倉庫NAYA以及棚屋KOYA。三座建築的距離適中，其中倉庫和棚屋被用作辦公室，已經進行了翻新。業主希望改善主屋的居住環境，使其成為兼具住宿和培訓功能的場所，為員工們提供舒適的體驗。

三座建築圍合出一個庭院，其中種有一棵高大的櫻花樹。儘管有著迷人的風景，但由於朝向既有廚房的背面，這座庭院未能發揮出自身的魅力。此外，由於停車場位於房屋西側，來訪者常常從棚屋和主屋之間經過，然後從既有廚房的門進入房間，這使得位於房屋北側的原始入口顯得破落又昏暗。為了改變這一點，建築師將原先的廚房改造為新的會客廳，並使其朝向庭院中連接棚屋和倉庫的櫻花樹露臺。

The courtyard which was surrounded by the three buildings, has a large cherry tree. Although it is an attractive place, it faced to the back of the pre-existing kitchen, and its charm was not utilized. In addition, the pre-existing entrance located on north of the house was dim and losing its role, because visitors parked on the west side of house, passed between KOYA and OMOYA and approached from pre-existing kitchen door. Therefore we converted the pre-existing kitchen into a new meeting space, then this space is opened to the cherry blossom terrace in the courtyard that connects KOYA and NAYA.

原先的入口被重置為一個朝向廚房的新入口，並通過木柴爐帶來吸引人的感覺。空間角色的互換為場所賦予了更加適宜居住的環境。
The pre-existing entrance is replaced as a new kitchen faced entrance, making it attractive to guests with wood stove. We interchanged their roles so that it would be appropriate place to stay.

同時，樓梯被整合至一個小型的榻榻米房間，走廊和南側榻榻米房間的牆壁被移除，形成一個簡潔的一體化空間。廚房、餐廳和南北兩側的榻榻米房間相互連接，既可以作為整體使用，也可以獨立運作。
In addition, the stairs was integrated to a small tatami room, the corridor and the walls of the southern tatami room were removed, and reprogrammed into a simple plan as a whole. Kitchen, dining, north and south tatami rooms are connected each other and are used as independent or connected.

屋頂、外牆和木製窗戶大部分保持了原貌，立柱、橫樑、帶有竹網的泥土牆、天花板以及各種木製結構也儘可能地被保留下來，與新增元素形成和諧的關係。
Most of the roofs, exterior walls, and wooden windows are kept as existing, and pillars, beams, soil walls with bamboo net, ceiling and wood elements are also kept as much as possible. We keep in mind harmony of new parts and existing parts.

該項目為傳統日式住宅賦予了彼此相連且可以互換的空間，為員工們創造了能夠同時滿足住宿和培訓要求的建築環境。藉助翻新講述關於傳統日式住宅的歷史，能夠讓從未在日式房屋中生活過的一代人得以體會到不同於現在的工作和生活方式。
Trying interchangeability of the traditional Japanese house plan and reconnecting each spaces, creates architectural environment which respond to living, accommodation and training for modern office workers. We will tell history of old Japanese house and try renovation design that can image future work and life to the generation who have never lived in an old Japanese house since birth.
