Outdoor Stairs: Climbing Up Along a White Wall

An outdoor staircase clinging to a white exterior wall. The treads are solidly built, covered with the same white lime plaster as the wall, continuous with the wall as one integrated unit, with no visible structure; the side is a continuous slope, and the front edge of the tread is rounded. There is no railing, or only a low solid wall of the same material as the wall serving as a handrail, with a rounded top edge. The staircase leads to a rooftop terrace. Strong sunlight shines from above and to the side, making each tread bright and casting the risers into shadow, forming a clear zigzag shadow pattern on the white wall, which is the strongest visual element on the entire facade. There is a small window on the wall and a climbing bougainvillea. Avoid: using metal railings and visible structures, making the staircase a separate volume, using materials of other colors, eliminating the zigzag shadows created by the treads.

一道貼著白色外牆的戶外樓梯。踏階是實體砌築的,以與牆面相同的白色石灰塗料包覆,與牆連續成一體,沒有可見的結構;側面是一道連續的斜面,踏面的前緣是圓角。沒有欄杆,或只有一道與牆同材質的矮實牆作為扶手,上緣圓潤。樓梯通往屋頂的露台。強烈的陽光從側上方照下,每一階的踏面明亮、立面落入陰影,在白牆上形成清楚的鋸齒狀陰影圖案,是整個立面上最強的視覺元素。牆上有一扇小窗與一株攀爬的九重葛。避免:使用金屬欄杆與可見的結構、把樓梯做成獨立的量體、使用其他顏色的材料、消除踏階造成的鋸齒陰影。
