Historic Structure Report, Volumes I-IX: Vanderbilt Mansion National Historic Site

John G. Waite Associates, Architects; Vance, Peggy; Lee, James

The preparation of a historic structure report for the Vanderbilt mansion began in July 1998, when Peggy Albee Vance compiled notes from her non-invasive physical investigation of the building into a first draft. Vance was a project manager and architectural conservator/historian for the National Park Service’s Northeast Region Building Conservation Branch. She also co-wrote the Historic Resource Study (prepared in 2000, printed in 2008) for the mansion, contributing to the architectural sections. Additional site visits by Vance and James Lee (an architectural conservator at NPS) in 2008, 2009, and 2010 recorded further information about the interior rooms and the building materials. Vance also prepared a “Background History” that described the history of the site, the original Langdon house which was demolished in 1896, and the initial phases of the Vanderbilt mansion construction. In 2016, the National Park Service contracted with John G. Waite Associates, Architects [JGWA] to complete Part I of the historic structure report; the same team had completed a Historic Furnishings Plan in 2015 which included descriptions of each room and development of the interiors. JGWA and its consultant, Mount Ida Press, updated the 2008-2010 history and descriptions with information gathered from additional research and site visits. In addition to editing the existing basement, first, second, and third floor descriptions, the JGWA team added descriptions of the exterior, sub-basement, and attic. Kohler-Ronan provided an overview of the mechanical systems that informed the description and conditions assessment. JGWA was also the architect for the exterior restoration of the mansion, completed in 2018. As part of that work, the firm created measured drawings of the exterior elevations. For this historic structure report, the firm added measured floor plans for the three primary floors as well as the sub-basement, attic, and roof. NPS received additional funding in 2017 to expand the history past World War II, to assess the condition of the mansion, undertake limited paint analysis (provided by Jablonski Building Conservation, Inc.), and to record the recent roof restoration, elevator refurbishment, and exterior restoration. The report was then divided into multiple volumes, with the conditions assessment, character-defining features, and paint analysis illustrations for each floor grouped with the corresponding architectural description: the introductions to the physical investigation, along with the descriptions of the exterior, sub-basement, and basement are in Volume II; the first floor in Volume III; the second floor in Volume IV; and the third floor and attic in Volume V.
