Corners: A Large Radius of Twenty-Five Centimeters

A rounded wall corner. The intersection between two walls is not a ninety-degree sharp edge, but a continuous curve with a radius of twenty to thirty centimeters. The surface coating smoothly transitions around the curve without any seams or shadow lines. When light hits it, a very gentle gradient of light and shadow appears at the corner, and that gradient is the source of the space's three-dimensional quality. The junction between the wall and the ceiling is treated in the same way. Avoid: using small-radius fine chamfers, having color separation or seams at the corner, keeping some corners at right angles, using corner beads to treat corners.

一處被抹圓的牆角。兩面牆之間不是九十度的稜線,而是一段半徑二十到三十公分的連續圓弧,表面的塗料一路轉過去沒有任何接縫與陰影線;光打上去時,轉角處會出現一道非常緩的明暗漸變,那道漸變就是空間的立體感來源。牆與天花的交接也是同樣的做法。避免:使用小半徑的細倒角、在轉角處出現分色與接縫、讓某些轉角維持直角、用護角條處理轉角。
