The Grand Central project has been under development since 2013 by the Carlyle Group and was acquired by Union Investment as part of a forward funding deal. In addition to 20,600 sq m of office and retail space, the complex will include three entrance lobbies, two restaurants, a bar and an auditorium, which will be accessible to the public. Special features of the project designed by Jacques Ferrier Architecture include a public promenade, several terraces comprising a total of 2,000 sq m, as well as a green roof that can be used for agricultural purposes. The sustainability of the property is documented by certification according to HQE Excellent as well as BREEAM Very Good.

The Grand Central business centre is being developed in the immediate vicinity of Saint-Lazare railway station in Paris's 8th arrondissement. Completion is scheduled for the middle of 2019. With over 100 million passengers a year, Saint-Lazare is the second largest railway station in Europe, served by five subway lines and numerous bus routes.
