Unibail-Rodamco-Westfield (URW) has awarded BESIX the construction of the Tour Triangle in Paris, designed by the architects Herzog & De Meuron, winners of the prestigious Pritzker Prize. The Tour Triangle will include office space, a conference centre, but also a health centre, a cultural centre, a crèche, a hotel and a restaurant. The building's carbon footprint will be controlled, in particular through the use of low-carbon materials, including a minimum of 50% concrete with reduced CO2 emissions, and recycled materials, in particular for the aluminium facades.
