広島県・呉市阿賀にある称名寺の鐘つき堂の計画である。称名寺は、かつて海だったところが埋め立てられ出来 た町と、それを取り囲む山の境界にあたる場所にある。寺に向かって長い階段をのぼっていくと、その先に鐘つ き堂が、さらに遠方に海が見えてくるという立地で、鐘をつくと、まるで海と街に向かって音が響きわたってい くような気持ちのいいところであった。そこでまず、鐘をつく時に海に向かうよう、配置を決定した。当初私た ちは、既存の鐘つき堂を尊重したシンプルな建築を提案していたが、ご住職から「もっと多くの方にお寺に興味 を持ってもらえるよう、皆がなんだろう？と思うものをつくってほしい」と意見をいただき、対話を重ねて今の 形へと決まっていった。鐘を吊るす屋根下空間は、既存の石垣を延長した洞窟のような場に、その上に周囲の山 並と呼応した特長的な屋根がかかっている。せっかく彫刻的な屋根を作るのであれば、何か面白い方法でつくれ ないかということで、木材をジェンガのように積み重ね、3Dで削り出す技術を使って作ることにした。検討に あたっては１／5のモックアップをつくり、実際に小さな鐘も吊るして檀家の皆さまに見ていただき、最終決定 となった。
現場で建て方が終わった時の仕上げのない木の塊の状態がきれいだったので、屋根を葺いてしまうのが惜しいと 感じたが、防水のことを考えるとやはり仕上げが必要である。そこで、木々がその表面を厚い皮で覆われているように、 杉皮をつかって屋根を葺くことにした。葺くにあたって、呉工業高等専門学校の皆さんに全面的に協力いただき、ワークショップで杉皮を一枚一枚を手作業でカットして、職人さん指導の下屋根へと張っていった。屋根を 見ると、その一枚一枚を人の手によって思いこめて作られていることがわかり、それがこの鐘つき堂の存在感へ と繋がっていると感じる。
This is a project for the bell-ringing hall of Shoumyouji Temple in Aga, Kure City, Hiroshima Prefecture. Shoumyouji Temple is located on the border between the town which was built on reclaimed land that was once sea, and the mountains that surround it. When one climbs up the long stairs to the temple, one could see the bell-ringing hall, and beyond it the sea in the distance, where one can almost picture the sound of bells echoing towards the sea and town. This sensation triggered our instinctive decision to orientate the bells to face the sea. At the beginning of the project, we proposed a simple architecture that respected the existing bell-ringing hall, but the monk asked us to make something that would spark people’s curiosity, attracting them to visit. After a series of conversations, we settled on the present form. The space under the roof where the bell is hung is a cave-like extension of an existing stone wall, with a distinctive roof over it that reflects the shape of surrounding mountains. Since we were making a sculptural roof, we wondered if an interesting technique could be used. We decided to stack wood in Jenga-style and carve out a form in 3D. We made a 1/5 scale mock-up with an actual small bell hanging from it for the monks to see, which ultimately finalized the design.
After the construction was finished on site, we felt it was a shame to put a roof on the building because it was beautiful in its unfinished wooden block state, but considering the need to waterproof, a roof was necessary. Therefore, we decided to use cedar bark for the roofing so the trees would look like they are covered with a thick layer of bark. With the full cooperation of the people of Kure National Institute of Technology, each piece of cedar bark was cut by hand in a workshop and installed onto the roof under the craftsmen’s guidance. When one looks at the roof, one would be able to see that every single piece of roof material was hand-made with great care, and this is what gives the bell tower a sense of presence.
Many people attended the bell tower’s completion ceremony, including monks and students of Kure National Institute of Technology. We were able to catch a glimpse of how this place will become a new base for the town, and a node that will bring everyone together. We sincerely hope that the Bell Ringing Hall will be loved by everyone for a long time.
