Few years after Poste Italiane moved out in 2002, Palazzo Aporti saw a new life through the profound redevelopment intervention, aimed at transforming into a business center the monumentalist building designed by Ulisse Stacchini and built between 1926 and 1931.    
The building, originally designed as Palazzo delle Regie Poste during the Fascist period, occupies an entire block bordered by Piazza Luigi di Savoia, Via Ferrante Aporti, Via Soperga and Via Luigi da Palestrina. The overall intervention involved a rearticulation of the interior spaces, with new volumes of linear and clean shapes defining the crowning of the building and housing offices, archives, warehouses, and commercial spaces. 
The original architecture has been preserved in the external façades, keeping the decorative and structural elements peculiar to the Fascist era, such as the large pronaos on the main entrance, also recalled in the internal courtyard. The complexity of the new interventions and the historical pre-existence have represented a challenge to the Construction Supervision, called upon to verify the executions in compliance with the constraint imposed by the ABAP Superintendence of Milan.    
Palazzo Aporti, built at the same time as the adjacent Central Station by the same architect, has art nouveau and liberty features combined with the canons of monumentalism typical of regime architecture. The approximately 26,000 m² of offices are distributed in three new buildings, including the historic façades and a new rectangular internal courtyard, designed to give space and light to the most central rooms. New levels and mezzanines – for a total of seven floors above ground and two floors of underground parking – have been made possible thanks to the considerable original height of the interiors and are made from a structural core entirely in steel with a reduced height to promote energy savings and lower consumption for heating and cooling of the rooms.     
The added façades are made with different solutions of steel mesh and glass, to mark with elegance, lightness and modernity a strong distinction between the new volume and the historic architecture, ensuring excellent visual comfort with natural lighting of the rooms. The plant design involves the production of heating and air conditioning using high-efficiency heat pumps powered by certified renewable sources, for a zero-emission system. The architectural project stands out for its thoughtful balance between the new and the historical, between the past and the future. Clean and essential lines, transparencies and soft colours give a new identity to the building without distorting its origin, adding beyond the historic eaves line of the fascist building, dialoguing with the existing and surrounding architectural language but renewing all aspects of energy, plant, and structural performance. 
The restoration of the internal courtyard, raised to the level of the mezzanine floor, stands for a renewal of the typical Milanese architecture, creating an Eden Garden that recalls the characteristic Milanese courtyards. The construction supervision of such a particular and complex project required the ability to organize, plan and manage a construction site full of different processes and professionalism, with a particular emphasis on strict compliance with the project bound by the Superintendence.
