The NUMA project is a conversion of a commercial building into an experimental place, which is emblematic of the type of activities it will host. Organised around collective and communal entities, it expresses itself by two unifying spaces put into tension. The first, on the ground floor, has a large area opening onto the street, a café, and is a fully flexible reception area. Due to this necessarily changing configuration it will be a multi-purpose space. The second space, on the top floor, is designed to host conferences and receptions and benefits from a large terrace. The work spaces are organised between these two levels.
