This historic structure report (HSR) was written preparatory to the rehabilitation of Building 32 by the Sandy Hook Unit of Gateway National Recreation Area (NRA) to accommodate several of the park's functions. Rehabilitation work was completed in June 1996. As a result, the current (2004) interior appearance of the structure differs greatly from that described in this report. A more detailed account of the work performed can be found in the appendix of this report. It was determined that this historic structure report would be a Level- B report, which required only secondary- source research and nondestructive investigation of Building 32. The research tasks included the review of all existing reports and documents located at the Northeast Cultural Resources Center, at the Boston Support Office, and in the park archives. All historical documents, photographs, and maps available in the park archives were also examined.
