The 45mm-thick wooden panels are assembled in a well within a 7,280mm square and stacked in three layers to create a pillarless interior space. The structure of the well girders is made of wooden panels with LVL horizontal members and conventional columns as vertical members. The connection between the upper and lower floors is created by the central atrium and the misalignment of the beams in each layer.
