Harry S Truman Building D Street Pavilion

The D Street Security Pavilion is the first realized phase of the Department of State’s multi-phase Perimeter Security Improvements Master Plan to enhance security at the Harry S Truman Building. The plan’s objectives were to secure the building, safeguard employees and visitors, and enhance the streetscape for pedestrians and neighbors.

The D Street Security Pavilion is the first of four planned entrance additions, designed to provide permanent screening outside the main building facades to mitigate risks associated with potential threats. A glass and stainless-steel storefront system encloses the interior, enriching visibility, natural light penetration, and a sense of openness required for security sight lines.

An accessible raised reception desk, open within, accommodates four receptionists. Two screening areas include X-ray machines and magnetometers, while universally accessible security turnstiles allow access into the existing lobby. Visual openness is further achieved with glass-enclosed entrance vestibules and remotely located mechanical and electrical rooms.
