The architectural design of the PRODEA offices, a 3500 sqm four-floor building, had three main goals: to intervene in a pre-war building [built in the 1920s] with a listed façade while maintaining its significant decorative features, to convert it in order to meet the highest standards of modern office spaces and to meet the design specifications of LEED and WELL. The LEED certification deals with the sustainability of buildings and their ability to meet the demands of the ongoing climate change while the WELL certification focuses on well-being and the improvement of health and everyday living of building occupants, by achieving high levels of soundproofing, improved ergonomics, reduced odors, monitoring air quality and implementing specific design standards. The interior of the building was modified to achieve an integrated rather than segmented operation, highlighting at the same time its distinctive features, such as the marble staircase with the handrail, the old elevator with the wooden booth and the plaster decorations of the ceilings. The first two floors accommodate open-plan and confined offices, while the management offices are located on the third floor and the breakout space with its external space are located on the fourth. An organic model of cluster desks has been implemented in the open-plan office spaces, which has a circular form and wave finishing, coated with sound-proofing fabric.
