播州平野を望む小高い丘の上に位置する、法華経の教えを学ぶ信者のための修行所である。宝塔を蓮の花、修行所を蓮の葉に見立て、緑・光・風の中に、蓮の葉に包まれた祈りの空間を浮かべることを意図した。 高さを低く抑え、のびやかなうねりをもつ3次元曲面の屋根は、木を主架構とした混構造とし、3D-CADと3次元測量を駆使して高い精度で組み上げた。講堂内部には放射状に配置した128本の湾曲集成材の小梁を露出させ、心地よい温もりと力強さを感じる、長辺30m×短辺20mの有機的な無柱の大空間を創出している。木の架構・銅板葺の屋根・庵治石積の基壇・左官塗の壁・無垢板の床など、自然の素材と粘り強い職人の手仕事でつくられた建築が、時の経過とともに味わいを増し、地域の風景の中に融けこむことを目指した。(岩井 正和)正導会教団神野修行所The temple of Shoudoukai-kyoudan in KannoUndulating 3-dimensionally curved wood frame roofうねりを持つ3次元曲面の木架構の屋根Owner: Shoudoukai-KyoudanLocation: Kakogawa-shi, HyogoMain use: TempleDesign and construction work: Takenaka Corporation・Architects: Masakazu Iwai, Shingo Katou・Structual: Takashi Kawano, Futoshi Ohori, Takehito Kumano, and Takuma Kawakami・M&E: Takashi Shinojima, Satoshi Nishiyama・Landscape: Yoshinori Onishi ・Site manager: Atsushi Okawara Site area: 2,999.50 m2Building area: 1,346.30 m2Total floor area: 1,998.16 m2Construction: Wood, Steel , Reinforced concreteNumber of stories: 2 floors above groundConstruction term: December 2010 to December 2011建築主:宗教法人 正導会教団所在地:兵庫県加古川市主要用途:寺院設計施工:竹中工務店・設計:岩井正和・加藤慎悟・構造:河野隆史・大堀太志 熊野豪人・川上沢馬・設備:篠島隆司・西山敏史・ランドスケープ:大西美典・作業所長:大河原篤敷地面積:2,999.50㎡建築面積:1,346.30㎡延床面積:1,998.16㎡構造:W+S+RC造階数:地上2階工期:2010.12~2011.12This facility, provided for the ascetic training of followers of the Lotus Sutra, is located on a hilltop overlooking the Banshu plain. The Buddhist tower and training center are meant to resemble a lotus flower and lotus leaf, respectively, and to depict a place of prayer enveloped in a lotus leaf and surrounded by nature. The roof with its three-dimensional curved surface and gentle undulations is a mixed structure that uses wood for the main frame, and was assembled with great precision using 3D-CAD and three-dimensional surveying. The interior of the hall has 128 exposed binding beams of curved laminated wood placed in a radiating pattern, creating a large (30 m x 20 m) wooden space that communicates both strength and comfortable warmth. This structure, entirely hand built by dedicated workers using natural materials, was designed to blend into the local landscape, and it is one that is appreciated more and more as time passes.(Masakazu Iwai)大地に浮かぶ木架構の屋根と重厚な石積の基壇26Works26
