Dutch colonial architecture which he favored. A sketch made by President Roosevelt dated April 12, 1937, shows the proposed building placed on the grounds very close to the site ultimately chosen and a ground plan roughly approximating that of the main block today. Based on his sketches, the building was designed by principal architect Louis A. Simon and consulting architect Henry J. Toombs. He built it with privately donated funds, at a cost of $376,000 and then turned it over to the federal government on July 4, 1940, to be operated by the National Archives. By his actions, Roosevelt ensured that his papers would become the property of the nation and be housed in a library on the grounds of his Hyde Park estate where they would be available to scholars. Robert D.W. Connor, the first Archivist of the United States, said of the President, "Franklin D. Roosevelt is the nation's answer to the historian's prayer." On June 30, 2013, the library building reopened to the public after a multi-million dollar renovation that was funded through both public funds and private donations. This was the first full-scale renovation since Roosevelt himself opened the library, with expanded exhibit space, HVAC updates, and research room improvements. Members of the Roosevelt family and the historian Geoffrey Ward spoke at a rededication ceremony that day. In July 2015, Archivist of the United States David Ferriero appointed Paul M. Sparrow to be the new director of the FDR Library and Museum.

At the time of her death in 1962 Mrs. Roosevelt's papers totaled three million pages. During her tenure at the library (1961–1969), Elizabeth B. Drewry raised funds for the wings to house Eleanor Roosevelt's papers. Construction was completed in 1972. The library contains the donated papers of others associated with Roosevelt, such as Henry Morgenthau, Jr.'s diary of 840 volumes.

When Congress passed the Presidential Libraries Act in 1955, it regularized the procedures initiated by President Roosevelt for privately built and federally maintained libraries to preserve the papers of future Presidents;
