Instead of sorting a building-materials mall only by product, the floors follow how people visit. Level 1 is a craft and method lab. Level 2 ties materials to daily life. Level 3 is for forums and brand events. Level 4 places smart-home products in imagined ways of living. Level 5 uses exhibition settings to send visitors away with ideas. The mall is planned as a place to talk, pause and look, not only to shop.
