Sea Change is a small complex of buildings and structures located in the ocean-side community of Northeast Harbor, part of the town of Mount Desert. The property contains five residential buildings, a workshop and a subterranean bomb shelter with dates of construction that range from the 1880s through 2005. The earliest buildings, Cabins 1, 2, and 3 and the caretaker?s house were originally erected in the 1880s to accompany a large Shingle Style cottage. In 1944 this cottage was removed and by 1947 a stunning modernist house, designed by the architect Walter K. Harrison, in collaboration with the sculptor Isamu Noguchi, was erected. Shortly thereafter the cabin interiors were renovated to more closely match the main house. The twenty-four person bomb shelter was constructed in 1961-2 immediately after the period when the owner served as United States ambassador to Belgium, in a period of heightened Cold War tensions, and reflects in its own manner another aspect of ?modern? mid-twentieth century design. Tragically, the main house was destroyed by fire in 1999. In 2005 the house was exactingly rebuilt on it original site to the original plans, and the interior furnishings, including a sculptural dining room table by Isamu Noguchi, were re-commissioned. As a (partially) reconstructed property executed in a suitable environment and presented in a dignified manner as part of a restoration master plan the Sea Change complex qualified for listing in the National Register primarily for its architectural significance, and as a work of a master architect. It is also significant under Criterion B, for its association with William A. M. Burden, (1906-1984), U.S. Ambassador, influential political advisor, and president of the Modern Museum of Art. The bombshelter is also significant, under Criterion A and C, as an example of a specific building type erected during the Cold War and that reflects significant political and military events in 1961.
