Louis Kahn | Salk Atrium: The Entrance is a Slit Facing the Sea

Between two perfectly symmetrical fair-faced concrete volumes lies a vast, empty travertine-paved courtyard with no vegetation, only a narrow water channel extending westward to the horizon. The entrance is not a door, but this entire "slit, embraced by the volumes on both sides, opening towards the sky and the sea"—one enters the moment one steps in. The concrete has a warm, pinkish-gray hue, with visible formwork marks and tie holes, and chamfered corners. Teak window frames are set into recesses in the concrete. At dusk, the water channel reflects the sunset, and the sides of the volumes are tinged with gold. Shot frontally on the central axis. Avoid: adding vegetation to the courtyard, widening the channel into a pond, painting the concrete, breaking the strict symmetry.

兩排完全對稱的清水混凝土量體之間,是一片鋪滿石灰華、完全沒有植栽的空曠中庭,中央只有一道細窄的水槽向西延伸,盡頭是海平線。入口不是一扇門,而是這整個「被兩側量體夾住、朝向天空與海的縫隙」——人走進去的那一刻就已經進入了。混凝土帶著溫暖的粉灰色,表面有明顯的模板痕與繫件孔,轉角處為斜切的倒角。柚木的窗框嵌在混凝土的凹處。黃昏時分,水槽反射夕陽,量體側面被染成金色。中軸線上正面拍攝。避免:中庭加植栽、水槽加寬成水池、混凝土上塗裝、破壞嚴格的對稱。
