History
The story of 333 Constitution Avenue Northwest Washington DC begins during the New Deal era, a period marked by ambitious public works projects designed to stimulate the economy and modernize federal infrastructure.

The annex was conceived as a multi‑functional facility that could accommodate both current Treasury operations and future governmental needs Not complicated — just consistent. Simple as that..
Construction commenced in 1937 under the supervision of the Office of the Supervising Architect of the Treasury Department. The project was completed in 1939 at a cost of roughly $3.Still, 5 million—a modest sum by today’s standards but a substantial investment during the Great Depression. The building’s design reflected the Art Deco influences prevalent in federal architecture of the 1930s, blending sleek geometric lines with practical, durable materials.
During World War II, the annex played a important role in war finance. Its conference rooms hosted critical meetings on bond sales, currency issuance, and wartime economic policy. Post‑war, the facility transitioned to housing the Bureau of Engraving and Printing’s administrative offices, further cementing its status as a center for monetary production.
