Black and White Stripes: Alternating Light and Dark

The front of a stone wall. Dark basalt and light limestone alternate layer by layer, each layer consistently twenty to thirty centimeters thick, forming continuous horizontal stripes; the keystone blocks of the arch are also dark and light, arranged radially along the curve. Corners and door frames use larger, whole stones. Avoid: painting fake stripes, making the dark and light layers inconsistent in thickness, not alternating the stones on the arch, making the stripes diagonal or vertical.

一面石砌牆的正面。深色的玄武岩與淺色的石灰岩逐層交替,每層厚度一致約二十到三十公分,形成連續的水平條紋;拱圈的楔形石塊同樣深淺相間,沿著弧線輻射排列。轉角與門框用較大的整石。避免:用油漆畫出假的條紋、讓深淺層的厚度不一致、拱上的石塊沒有跟著交替、把條紋做成斜向或垂直。
