In spatial terms, it was decided to integrate the programmatically defined enclosed functions into three logical volumetric units. The composition is point-connected and consists of a large cuboid on a rectangular base, an elongated lamella, and a volume based on a square. The structure is partly embedded in the ground and partly hovers above the sloping terrain. It is positioned in an absolute orientation, with its longitudinal axis aligned in the north–south direction.
Conceptually, considering the character of the City of Trogir, its history, its fortification and secular form, as well as the form that emerged from its economic base (the shipyard), the design adopts a metaphor and a partial historical interpretation. The structural system and installation channels within the roof planes of the three-part hall influence a uniform, rhythmic gradation at the top of the volume. The mass of the hovering cuboid, both functionally and metaphorically, culminates at the roof in a metaphor of the crenellations of the walls of Kamerlengo Fortress. The variable roof height simultaneously and functionally enables evenly distributed natural northern light within the hall.
