Dueo Galeo Trieo

An open block of three buildings with a strong architectural identity in Issy-les-Moulineaux

Located at the gateway to the town of Issy-les-Moulineaux (92), in the dynamic Seine Ouest district, Galeo, Dueo et Trieo benefit from a strategic position. Right by the banks of the Seine and the ring road, the real estate project is also well served by public transport: the RER C, the tramway T2 and the metro (lines 8 et 12) enable access to the city centre in just a few minutes.
Christian de Portzamparc, winner of the Pritzker Prize (‘Nobel Prize of architecture’) in 1994, describes his design as an « open block » with the construction of 3 buildings : Galeo, Dueo et Trieo which mark the gateway to the town of Issy-les-Moulineaux from Paris. A glass-scaled nugget, a soft pebble, or a “Chinese lantern”, as the architect calls it.
The building offers high-quality services with a 350-seat company restaurant, cafeterias, an interior landscaped garden, and large terraces in the Dueo and Trieo buildings. It has a prestigious tenant: Bouygues Immobilier.
