Tour Eqho, Office skyscraper in La Défense, France
Tour Eqho is an office building in La Défense featuring a distinctive geometric form with a semi-cylindrical protrusion on its main facade, rising 131 meters high. The structure contains 40 floors of office space along with an auditorium, several restaurants, a fitness center, and parking facilities.
The building was constructed in 1988 under architect Jean Willerval's direction and initially served as IBM's French headquarters. The company relocated after 2010, and various corporate tenants have occupied the offices since then.
The tower shapes the character of La Défense as a modern business hub and reflects how 1980s architecture transformed the district's appearance. Today multiple companies occupy office space here, contributing to the area's role as a major employment center.
The building serves as an office complex and is accessible to visitors or clients of resident companies, though access hours depend on individual tenants. The site offers parking and benefits from good public transportation connections as part of the La Défense business district.
The building earned an informal nickname among real estate professionals due to its semi-cylindrical facade element, which humorously resembles a particular everyday object. This playful moniker reflects how Parisians sometimes give witty names to modern structures in their skyline.
