“What if we decided we needed a little more Guggenheim?” asked New York- and Athens-based group Oiio Architecture Office. In a shocking announcement on its Facebook page, the Solomon R. Guggenheim Museum today disclosed that it will be expanding—vertically: “We are pleased to announce that beginning today, the Solomon R. Guggenheim Museum will begin construction to expand the original Frank Lloyd Wright design by an additional 13 floors.” The museum has always faced spatial limitations,and as the Whitney has taken to expanding over the High Line, renderings for Oiio Architecture Office show the Guggenheim rising vertically from its Fifth Avenue site, continuing the building’s signature spiral form. While this expansion is sure to garner criticism from preservationists, as the buildings is currently listed with both the National Register of Historic Places and the New York City Landmarks Preservation Commission, representatives from the museum have stated that the proposed addition will respond respectfully Wright’s original design.
