The structural system is fundamental to the project and remains clearly visible throughout the building. The large interior spaces require long spans, while the rooftop pool introduces significant additional loads. Two robust transversal walls anchor the volume, defining the central atrium and the main circulation. Along the façades, independent rectangular columns support the slabs and extend beyond their edges.

At the top, the slab curves to accommodate an infinity pool overlooking the ocean. The curved profile introduces a softer element within the otherwise rigid geometry of the building, creating a transition from the heavy concrete base to the lighter upper level. The curvature also has a structural purpose, increasing the stiffness of the slab and allowing it to support the weight of the pool water.

At the centre of the building, a concrete cone runs through all levels. It becomes a fixed point around which the interior is organised, while bringing natural light down into the entrance atrium. Structure, circulation and light are therefore concentrated in the same central space.
