Visitor Guide
You’re not here to ‘see a building’—you’re here to read a site: stand in La Défense and imagine how a near-300m beacon would have changed the district’s silhouette and ground life.
From the La Défense esplanade with a clear skyline view, late afternoon; photograph the existing towers and annotate later—this is an archive visit in disguise.
Not accessible as a building—project was canceled. Visit La Défense to understand context instead.
Unbuilt towers are often more honest about their era’s obsessions (green branding, icon race, parametric skins) than what actually gets constructed.

Design & Structure
Speculative high-rise design: concept iterations, environmental narratives, and envelope studies typically explored through advanced 3D modeling and performance simulation, then abandoned due to economics, politics, or changing developer priorities.
Proposed translucent/advanced envelope strategies typical of the era; material intent was about ‘beacon’ effect and environmental branding.
Would have required a robust lateral system and sophisticated facade-to-structure coordination; unbuilt projects often push structural ideas before value engineering pulls them back.
