Why does the stair in the old parish house down in Därligen feel so effortless to climb? Because the treads are dished. Heinrich planed about three millimetres of hollow out of the middle of every single timber step back in the eighties, so your foot naturally settles into the wood instead of rolling off the front edge. Forty years on, nobody consciously notices it, but your body feels the relief immediately. That kind of quiet generosity is what keeps me in love with this work. @emlynhilson
