By 2001, there were plans to expand the Pierpont Morgan Library. The library presented preliminary plans to the LPC in 2002, in which it would build a new structure between 231 Madison Avenue and the original library's annex, to be designed by Italian architect Renzo Piano and Beyer Blinder Belle. The commission also sought to restore landmark status to 231 Madison Avenue, a move the library did not oppose. In 2003, the Pierpont Morgan Library's buildings were closed for construction and expansion. In the interim, it sponsored numerous traveling exhibitions around the country. The library reopened on April 29, 2006, as the Morgan Library & Museum. With the completion of the renovation, the private office and vault of J. P. Morgan was also opened to the public. A restoration of the main building's interior spaces was completed in 2010. The Morgan Library & Museum announced a four-year restoration of the main building's facade in February 2019, the first in the building's history.
