GCHQ represents a revolution in the management and working practices of the British government’s major intelligence organizations. Integrating 4,000 staff from 50 buildings and numerous departments in one dynamic headquarters environment, the facility's three identical, interdependent, four-story buildings are configured in a circle, creating the effect of a single, 1.5-million-square-foot structure that encloses a landscaped garden. A glass-roofed internal “street” runs the full circumference of the buildings. One result of the open-plan workspace is that no colleague is more than a five-minute walk from any other colleague. Shared services include a restaurant, cafés, a gym and childcare facilities.
