The museum's building and renovation project, "Building for the Future",[1] began in 2005 and was originally targeted for completion in 2012 (though it was not completed until 2013)[2] at projected costs of $258 million.[14] The museum celebrated the official completion of the renovation and expansion project with a grand opening celebration held on December 31, 2013, and additional activities that continued through the first week of 2014.[15] The $350 million project—two-thirds of which was earmarked for the complete renovation of the original 1916 structure—added two new wings, and was the largest cultural project in Ohio's history.[9] The new east and west wings, as well as the enclosing of the atrium courtyard under a soaring glass canopy, have brought the museum's total floor space to 592,000 square feet (55,000 m2) (an increase of approximately 65%).
