Triangle is a 180-metre tower designed by world-renowned architects Herzog & de Meuron. It will combine living spaces, workplaces, a transit hub, services and leisure activities in one place, transforming a part of Paris that is currently best known for trade fairs into a destination brimming with life.

With a hotel, a crèche, a health centre, a cultural centre, a conference hall, shops, a scenic viewing area and panoramic restaurants, Triangle will be open to all for diverse and overlapping activities.

To accelerate the city's transition for a low-carbon future, Triangle will be constructed using materials that have low carbon emissions and are subject to the most demanding international environmental certifications. Triangle sets in motion a new cycle of ecological transformation: the companies housed in Triangle will free up obsolete, energy-intensive buildings that can then be eco-renovated or converted into housing.
