Sagamore Hill National Historic Site
Oyster Bay, NY
Client: U.S Department of the Interior, National Park Service

Project Type: Structure Report Update; Conditions Assessment; Comprehensive Interior and Exterior Restoration 

Sagamore Hill was Theodore Roosevelt’s Long Island home from 1887 until his death in 1919. The 26th President of the United States’ home is preserved as it was during his residency and designated as the Sagamore Hill National Historic Site. During Roosevelt’s time in office, his “Summer White House” was the focus of international attention.

John G. Waite Associates, Architects investigated Theodore Roosevelt’s home, identifying and documenting masonry and wood shingle building envelope concerns, and the surrounding site conditions that contributed to moisture problems. The recommendations from this report guided the planning and design efforts for the long-term preservation of the home and its collections. After preparing an expanded historic structure report that incorporated new research regarding original building systems and mid-century renovations, JGWA completed comprehensive drawings and specifications for the exterior restoration and the interior restoration of the house, including the insertion of new HVAC, lighting, electrical, security, and fire detection and protection systems. Construction began in 2012, with JGWA providing construction administration services through the historic house museum's grand opening in the summer of 2015.
