The Staircase is a Solid Wood Block

A rustic staircase made of solid wood blocks. Each step is a single block of solid wood, twenty centimeters thick in cross-section, with a rough-sawn or adzed texture on its surface. They are cantilevered, embedded into a fair-faced concrete wall on one side, with the other side completely suspended, without beams or supports. The handrail is a slender black circular iron rod, three centimeters in diameter, fixed to the wall. The ends of the wood blocks are cut perfectly straight. Avoid: using closed stairs with risers, adding wooden cladding and risers, using an iron frame to support the treads, making the handrail a thick wooden balustrade.

一座由實木塊構成的質樸樓梯。每一階是一整塊斷面二十公分厚的實木,表面是粗鋸或斧鑿的紋理;它們單邊嵌進清水混凝土牆裡懸挑出來,另一側完全懸空,沒有梁也沒有支撐。扶手是一根直徑三公分的黑色細圓鐵桿,固定在牆上。木塊的端部切得筆直。避免:使用有立板的封閉樓梯、加入木作包覆與踢面、使用鐵件骨架支撐踏板、把扶手做成粗厚的木製欄杆。
