The creation of the headquarters was a massive undertaking involving a board of designers mediated by Harrison & Abramovitz. The construction was carried out by a consortium of four companies: Fuller, Turner, Slattery, and Walsh. The project aimed to create a space that reflected the forward-looking, inclusive nature of the organization.
