For over a decade, a concrete and steel skeleton defined the city’s landscape, remaining as a suspended promise within the characteristically horizontal urban fabric that shapes Pisa’s skyline. The transformation of the North Tower by ATI Project addresses this very context as an act of urban regeneration, converting a structure originally intended for residential use into a 14-story Business Center. The project provides the area with the city's first true corporate tower, a hub capable of converging the excellence of a district heavily defined by its academic, healthcare, and technological presence. Rather than passively adapting to its surroundings, the intervention acts as an urban catalyst, subsequently unlocking the destiny of the entire surrounding building complex.
Standing 45 meters tall with a semi-elliptical footprint, the architecture addresses its volumetric prominence through a lightweight curtain wall, conceived as an active filter between the workspace and the city. The adoption of fully glazed perimeter balustrades eliminates all visual barriers, pushing natural light deep into the floors to maximize interior environmental comfort. This absolute transparency is precisely calibrated on the southern facade, where a double-skin polycarbonate installation shields the envelope at points of maximum solar exposure, ensuring microclimatic control without compromising the structure's light and ethereal identity. Beneath this glass skin, the integration of building services required a feat of technical micro-surgery to fit high-efficiency, centralized energy systems into a pre-existing skeleton originally born for residential purposes. Every technological component is coordinated by an automated BMS that optimizes loads in real time, working in synergy with natural ventilation and LED lighting.
The top seven levels of the building house the headquarters of ATI Project, structured around a central circulation core from which two distinct functional wings develop. The north side follows the organic flow of the curved facade, translating into a fluid open space entirely projected outwards, where the perimeter glazing is kept free of partitions to foster spontaneous collaboration. Conversely, the south wing introduces a spatial sequence dedicated to privacy and concentration, alternating open-plan areas with individual offices and modular meeting rooms. On the thirteenth floor, the layout shifts gears to host executive and management areas, relying on the continuity of glass to visually narrate the firm's ethos of transparency. The architectural honesty of the interiors emerges in the exposed ceilings, where the network of building systems becomes a conscious aesthetic element that showcases the engineering intelligence of the North Tower. This industrial character is balanced by the warmth of timber, light finishes, and a floor-specific color gradient that serves as a visual and identity compass for the studio’s various departments.
The project dismantles the traditional insularity of corporate centers, opening its boundaries to the neighborhood and the wider city. The ground floor is articulated as a vibrant, outward-looking covered plaza, where the entrance lobby integrates a café and a flexible, multi-purpose hall for corporate, cultural, and institutional events. This system of public spaces extends vertically to reclaim the building’s roof, where a 360-degree panoramic terrace returns an unprecedented vantage point over the city and the surrounding landscape to both the public and the professional community that inhabits the North Tower. By conceiving high-end architecture as a platform for sharing, the North Tower demonstrates how the responsible reclamation of an unfinished structure can generate well-being and a sense of belonging, transforming a private volume into a vital and ethical resource for the entire community.
