Terral | Sky Room: Digging a Square Hole in the Ceiling

Turrell | Skyspace: A Square Hole in the Ceiling
A minimalist room with a square or circular opening in the center of the ceiling, without glass and with an extremely thin edge, directly facing the sky. Because the edge has no thickness, the sky does not appear as a framed view, but rather as a flat color block pasted onto the ceiling. A strip of color-tunable lights is hidden along the lower edge of the wall, slowly changing the indoor color temperature before and after sunrise and sunset—when the indoor light approaches the brightness of the sky, the color of that "color block" dramatically changes, from blue to purple, purple to black. The room contains only a continuous bench along the wall. The material is seamless white plaster. Photograph from inside looking up at dusk, with the colors of the opening and the gradient of the walls simultaneously visible. Avoid: adding glass to the opening, making the edge thick, fixed indoor lighting, adding other furniture or decorations.

一個素淨的房間,天花正中央開著一個沒有玻璃、邊緣被削到極薄的方形或圓形開口,直接對著天空。因為邊緣沒有厚度,天空看起來不像被框住的景,而像一片貼在天花上的平面色塊。牆的下緣藏著一圈可調色的燈,日出與日落前後緩慢改變室內的色溫——當室內的光與天空的亮度接近時,那片「色塊」的顏色會劇烈變化,藍轉紫、紫轉黑。室內只有一圈沿牆的座椅。材質為無縫的白色抹灰。黃昏時從室內仰拍,開口的色彩與牆面的漸層同時可見。避免:開口加玻璃、邊緣做厚、室內照明固定不變、加入其他家具或裝飾。
