The General Service Administration commissioned a Determination of Eligibility to ascertain if Buildings 1, 2, and 3 on the Menlo Park campus qualify for listing in the National Register of Historic Places. This preliminary evaluation is the basis on which subsequent formal determinations can be made in consultation with the State Office of Historic Preservation. Knapp Architects surveyed, photographed and described the three buildings and their unique characteristics, summarizing the original design, subsequent alterations, and current condition. Jill Johnson Historic Preservation Services studied the extensive history and described the historical context. Knapp Architects compiled and formatted a comprehensive document including text, photographs, historic and as-built drawings. These modern buildings, coming of age in terms of historical evaluation at 50 years, reflect variations in the Mid-Century Modern style and their exterior geometric seismic augmentations invite curiosity.
