The architecture of Palazzo Lombardia presents considerable organisational flexibility, due not only to the standardisation of the equipment and the use of partitions, but also high quality and good privacy in the areas dedicated to the Assessors – and high level of liveability in all the offices.

The project involved distributing the support areas to places with reduced exposure and the possibility of fulfilling the vertical and horizontal distribution models. The ground floor mainly counts public functions such as porticos, squares, commercial areas for restaurants, bars, stores and services. It also includes a kindergarten, an auditorium, a fitness centre, a showroom, post office, protocol and a space for the region. The first floor is made up mainly of mixed public/private functions. It has meeting and conference rooms, archives, libraries and media libraries. Floors two to eight are offices with operational seats (about 700) and areas dedicated to the Assessors of the Directorates-General, all furnished by Aresline.
