The project's architectural as well as structural highlight is the huge timber roof rolling across an area of 645,835 ft², spanning the building like a giant wave, that was designed by the Austrian company Graf‑Holztechnik.

The primary structure, consisting of mighty glulam beams, rests on steel and reinforced concrete columns up to 66 ft high.

The structure supports a record amount of approximately 282,517.3 ft³ of cross‑laminated timber slabs. The three- and five-layer panels have a thickness of ~ 4.7 to 9.5 inches and a span length of up to ~ 32.8 ft. The thickness was calculated for each slab in order to dimension the structure to be as slender and economical as possible.
