Description(English)	The Cloud of luster is a wedding chapel located inside a wedding ceremony hall in Himeji city, Japan. The design aims to translate the modern wedding ceremony spirit into physical space. The chapel is all white, a cloud shape enveloped almost entirely in curved glass opening it to the surrounding garden and water basin. The columns are toped in hyperbolic capital-like heads smoothly connecting them to the minimalistic ceiling. The chapel socle on the basin side is a hyperbolic curve allowing the whole structure to appear as if it is floating on the water and accentuating its lightness.
Description(Native)	結婚式場内に位置する、チャペルの建て替え計画。新郎新婦にとって特別な日を、より特別な日にする非日常的な風景が求められた。 水盤に浮かぶ雲をイメージしたチャペルの輪郭は全て曲線で描かれ、その軌跡に沿った曲面ガラスが空間を包み込んでいる。曲面ガラス、ステンレスサッシなどの制作コストを抑えるため、軌跡の半径は2500ミリに規格化されている。雲形の屋根とそれを支える柱を緩やかな曲面でシームレスにつなぎ、天井面には一切の設備を配置せず、照明や空調吹出口は全て床面に設置することで、空間を覆う雲を淀みのないものにした。床面は透明なガラスビーズを樹脂で固めたもので、日差しによって水盤のようにキラキラと光る。 ここから羽ばたく新郎新婦の新たな門出の象徴として、このチャペルはエル・ブランシュ（白い翼）と名付けられた。

Judging Comments	The Cloud of Luster, a wedding chapel in Himeji, Japan, transforms the modern wedding spirit into a serene architectural experience. Entirely white and cloud-shaped, it is wrapped in curved glass that opens to a surrounding garden and water basin. Hyperbolic column capitals flow seamlessly into a minimalist ceiling, while a curved socle along the basin side creates the illusion of floating on water. The jury valued how the design conveys purity, lightness, and celebration through refined form and spatial poetry.
