In terms of spatial planning, the designers follow the consistent way of restraint and balance, pursue the sense of scale brought by large space, reserve hollow space by using the advantage of storey height. The suspended conference room and the sinking book bar use the staggered floor space structure to distinguish the functions, and the three floors are integrated and relatively independent through the continuous up and down response of the stairs. The top floor uses the mobile skylight to guide the scenery into the room, extending the sense of hierarchy of the space longitudinally.
