Located at one of the crucial nodes in the capital's metropolitan development, the station was designed not only to fulfil the requirements of a strategic junction for international and regional traffic but also as an "urban piazza" capable of mending the caesura between the Nomentano and Pietralata neighbourhoods, which have always been separated by the railway line. The "bridge" building, inspired by the nineteenth-century passages typology, is an imposing volume about 350 m long and 60 m wide, suspended over the tracks and resting on the two entrance halls from Nomentano and Pietralata. A vast metal roof consisting of an extra-roofed reticular structure serves as protection and screening for the entirely glazed façades, from which the blocks housing VIP lounges, internet offices, offices and restaurants are suspended.

The gateway to the Piedmontese capital for those travelling on high-speed trains, the 386 m long and 30 m wide building reinterprets in a contemporary key the passages of the 19th century, a consolidated building typology in Turin's urban fabric. The work, supported by 106 arches, is a veritable urban gallery where one can stop at restaurants, bars and shops, and resembles a long glass and steel tube with an envelope of "intelligent" technology: monocrystalline photovoltaic cells integrated in the glass panes create a sunscreen of variable density, producing energy for 680,000 KWh/year and contributing to environmental comfort.

One of the main interchange stations in southern Italy, the building with a length of about 400 m and a width of about 44 m, with a reinforced concrete and steel structure, Corian cladding and glazed panels, is a "bridge" designed with the intention of overcoming the barrier of the existing railway line: its fluid and enveloping forms, vaguely zoomorphic to the point of recalling the skeleton of a dinosaur sleeping on the tracks, welcome visitors into a bright and futuristic environment. Solar panels integrated into the roof of the canopies, combined ventilation and integrated cooling and heating systems make it possible to minimise annual energy requirements.

In Hong Kong, one of the most overcrowded and congested metropolises on the planet, the KWT station is not only an important national and international railway junction but also an urban park that has increased the city's green space by 15%. The complex, a 180-metre long structure with an average width of 65 metres and 15 tracks, is the largest underground railway station in the world and includes more than 3 hectares of parkland, with a total of 6 hectares of open space. If on the outside visitors walk on the softly curved roofs dotted with greenery, exploring the urban skyline from different perspectives, on the inside an explosion of glass and steel frames a majestic and swarming space that is not at all intimidating, thanks to its pleasantly light-flooded atmosphere and rarefied tones.

The Kénitra station, one of four on the high-speed railway line connecting Tangier to Casablanca via Kénitra and Rabat, is part of an ambitious project for the socio-economic and technological development of the Moroccan territory. Conceived as a trait-d'union between the new city and the historical fabric thanks to the footbridges that bypass the tracks and reconnect the two parts of the city, the complex on three levels and a basement is articulated around a triple-height hall that is the representative and functional epicentre of the place, from which to go to the tracks or where to stop for tea. Paying homage to the architecture of Islamic countries and in particular to the element of the mashrabiyya, a traditional grid that filters light, ventilation and prying eyes, the envelope is conceived as a large screen with triangular elements in high-performance fibre-reinforced concrete, which regulates the building's thermal comfort amidst suggestive chiaroscuro effects.
