Sisters towers
Context & Issues

Following on from the Trinity Tower project, Europe’s leading listed commercial property company Unibail-Rodamco demonstrated its continued confidence in our teams by appointing us to the manage design studies and supervise implementation of the iconic Sisters Towers project, which is located in La Défense business district. Designed by architect Christian de Portzamparc, this complex will comprise two towers joined by a connecting section to form a single high-rise building whose avant-garde profile will redraw the district’s skyline.
