当弗朗西斯·凯雷（Francis Kéré）着手在其家乡——布基纳法索甘多村（Gando, Burkina Faso）建造一所学校时，他选择了黏土；这种材料在当地社区中向来与匮乏相关，而非建筑。为证明其结构可行性，他制作了试验砖块，并将其中一块浸入水中五天，随后向村民展示该砖块未发生失效。接着，他培训当地村民亲自砌筑墙体，而非从城市引入专业施工队。此后，已有超过200名甘多村民因这一决定成为建造者。这所学校所承载的，远不止一份材料清单所能涵盖：它留下了那些双手的印记——这些手将在脚手架拆除之后，长久地生活于村庄之中。

When Francis Kéré set out to build a school in his home village of Gando, Burkina Faso, he chose clay, a material his own community associated with scarcity, not architecture. To prove it could hold, he built test bricks and submerged one in water for five days before showing his neighbors it hadn't failed. Then he trained the villagers themselves to raise the walls, rather than bringing in a construction crew from the city. More than 200 people from Gando have since worked as builders because of that choice. The school carries something a materials list alone cannot: the trace of the hands that will go on living in the village long after the scaffolding came down.
