Kouunji Kyakuden 客殿について

この計画は、曹洞宗高雲寺の施設のひとつである築140年の客殿の再建である。長年、地域の人々に愛されてきたこの客殿は、損傷が激しく補修の限界を超えていたことから建て替えの必要に迫られていた。建築家は、施設全体の更新と調和を図り、地域の記憶を次世代へ継承する幾つかの仕掛けをこの建築に込め、これらの問題を解決した。その結果、新たな客殿は、単に郷愁を誘うだけでなく、歴史的文脈の中で存在感を放つものとなった。

The old reception hall had been loved by the local community for long time, but it was beyond the scope of repair. Therefore architect took on various creative challenges. He aimed to solve these issues by updating it to modern functions, harmonizing it with other facilities, and devising some mechanisms to pass on the memory of local society to the next generation. As a result, this architecture was able to achieve not a sense of nostalgia but also a presence for the future.

製造技術: This project had a clear floor plan with each function directly connected around the entrance hall, but there were many difficult construction tasks in some places. Ground reinforcement and strong foundation construction for soft ground, woodwork including special joints to structurally reuse old materials, fabrication of delicate and movable cedar lattices, and the revival of forgotten traditional natural paints "Kumezo". This project was realized through thoughtful design and exceptional craftsmanship.
デザインの課題: Various choices and challenges were made to pass on the memory of the local community. By choosing a common wooden house construction method rather than the traditional temple construction method, they were able to shorten the construction period, reduce construction costs, and as the result have time to repair and reuse old materials. The exterior has a roof shape unique to the region, and the walls and window lattices are finished with local cedar wood and with a revived traditional natural paint "Kumezo". As a result, this architecture achieved a special harmony and presence.
リサーチ: Type of Research: About the relationship between Kouunji and the local area.
Methodology: History, landscape and topography research, annual event research, monk behavior research, and interviews with local residents,
Conclusion: Kouunji is the core of the local community that people have visited since childhood for events and daily life. The architect concluded that in addition to modernizing the function of the ceremony hall and harmonizing it with other facilities, it was essential to create a mechanism to pass on the memory of the local community to the next generation.
インスピレーション: Researching the old reception hall and the landscape and history of the area provided architect with important inspiration. In particular, the old reception hall was tilted due to the soft ground, but it was discovered that some of the main structures, such as beams and columns, were valuable materials that are currently unavailable, and could be reused if repaired. And new architecture was important not only for its shape in the landscape, but also for its presence within the historical context.
プロジェクト期間: The project started in February 2002 and was completed in November 2004 in Tsukubamirai City, Ibaraki Prefecture.
オペレーションフロー: Kouunji is an essential presence for the region.
Because the parishioners of Kouunji are local residents and their relatives, and annual events and celebrations and condolences are mainly held for the parishioners. The reception hall, located to the side of the main hall, functions in conjunction with the main hall during events, and is used for religious ceremonies, waiting areas, dinners using the kitchen function, and a meeting place. It also functions as an emergency temporary evacuation center in the event of a disaster. There is also a temple office that oversees them.
