7. La Halle Freyssinet

Station F in Paris

Built in 1920, the Halle Freyssinet building started out in life as a freight train station – but from 2016, its new phase will begin as the world’s largest digital business incubator with room to house over 1,000 start-ups. Architect Jean-Michel Wilmotte is in charge of the building’s reincarnation that will provide an array of business functions, including business-meeting rooms, areas for co-working, a spacious auditorium and a restaurant and bar open 24 hours a day. Situated on the south bank of the river Seine, the venture is backed by the Municipality of Paris with financing from Caisse des Dépôts et Consignations and French entrepreneur, Xavier Nile.
