One of the project’s primary challenges was accommodating a dense mixed-use program while maintaining openness, accessibility, and continuity at the scale of the urban block. The proposal responds through a layered spatial organization structured around three primary architectural conditions: the base, the middle section, and the upper volumes. At the ground level, a sunken public plaza forms the center of the project, extending pedestrian movement into the site while creating an intermediate civic space between the city and the harbor. Commercial functions, covered public areas, and open circulation paths activate the lower levels and reinforce permeability across the block. The middle section introduces curved voids and suspended volumes that reduce the visual heaviness of the building while improving daylight access, visibility, and internal connectivity. These carved geometries create terraces, atriums, and intermediate public zones that support movement and visual continuity between different parts of the project. The upper levels consolidate the building’s metropolitan presence within the evolving skyline of Piraeus through distinct rooftop forms and planted terraces that maintain visual openness while reinforcing the project’s urban scale. The façade system combines transparent and solid surfaces to balance environmental performance, public interaction, and urban presence. Large glazed areas activate the commercial zones at the lower levels, while recessed terraces and shading systems regulate light exposure and contribute to the building’s spatial depth.
