Intelsat headquarters

Intelsat headquarters is a modernist office building in North Cleveland Park consisting of thirteen octagonal office pods connected by six glass-domed atria. The structure spans an expansive campus near Connecticut Avenue and contains 546,000 square feet of office space across seven floors.

The building was completed in 1984 and served as headquarters for Intelsat, an international satellite communications organization founded in 1964. Its construction marked a major expansion of the organization's operations as global satellite technology advanced.

The structure exemplifies high-tech architecture through its metallic finishes, modular design, and glass cupolas, reflecting the space technology advancement of its era.

The facility is located at 3400 International Drive in an accessible area with natural light reaching about 70 percent of the office spaces. Visitors should note this is a private building and access is typically limited to business-related activities.

The groundbreaking ceremony was unusual in architectural history as it was initiated by a satellite-triggered explosion, the first time space technology marked the start of a building project. This event reflected the direct connection between the structure and its mission of global satellite communications.
