English	The curved lines of the vaulted roof give a sense of expansiveness to the interior space and the characteristic large sas h window in one corner of the living room gives the interior space an outdoor atmosphere when open. While the build ing structure is mainly reinforced concrete, the roof is a wooden structure consisting of a series of continuous arches b uilt with CLT panels that required extremely precise planning and construction techniques to implement. The floor color is emerald green, which evokes the shallow waters of the ocean. The entrance is reminiscent of the undersea, with a w hite, shell-like staircase floating in the air.
Native	ヴォールトの屋根の曲線が内部空間に広がりを与え、リビングの⼀⾓にある特徴的な⼤きなサッシ窓は、開放時には屋外のような雰囲気を室内空間に与える。建物の構造はRC（鉄筋コンクリート）が主体だが、屋根は7m×900mm のCLT（Cross Laminat ed Timber：直交集成板）パネルを⽤いた連続アーチの⽊造構造であり、この設計を実現するには、極めて緻密な計画と施⼯技術が必要だった。床の⾊は、海の浅瀬を思わせるエメラルドグリーン。エントランスは海の中をイメージし、⽩い巻⾙のような階段が浮かんでいる。また、インフィニティプール、薪サウナ、ジャグジー、アウトドアキッチンといった、⼤切な家族や仲間とゆったりと過ごすための、充実したアメニティを計画した。

Judging Comments	This award-winning design has been universally praised for its breathtaking fusion of structure, materiality, and atmosphere, redefining the boundaries of contemporary architecture. The vaulted roof’s fluid curvature creates an unparalleled sense of expansiveness, seamlessly blending the interior with the natural world. The grand sash window in the living room further enhances this effect, erasing the division between indoors and outdoors—a concept that embodies architectural brilliance. One of the most remarkable achievements of this project is the ingenious use of CLT panel construction, which demanded unprecedented precision in planning and execution. The wooden arches form a rhythmic, organic sequence, evoking the sensation of walking beneath an ethereal forest canopy. This mastery of engineering has been hailed as a groundbreaking approach to integrating structural integrity with artistic expression. This project has been celebrated as a landmark achievement in modern architecture, where technical excellence meets profound artistic vision. The jury has applauded its flawless craftsmanship, innovative material use, and emotionally resonant design, marking it as a benchmark for future architectural masterpieces.
