Each scroll takes you to the place one layer of the castle comes from: a rice valley, a stone quarry, a cedar forest, a paper village. At every stop, the studio says one thing it believes. The studio's five buildings sit on a map of the valley; pick one and its technical drawing inks itself in. The last chapter ends with a project enquiry form. Rock, wood, paper, brush strokes and music are all made in code, and the whole page works on a phone too.
