[1] The Honolulu Museum of Art acquired the estate as a bequest from Alice Spalding in 1968 and operated it as an annex for the display of Japanese prints from 1970 to 1978.
Following interior renovation, the museum, with its doors by artists Robert Graham and Tony Berlant, opened to the public in October 1988.
The three-dimensional set for Maurice Ravel's opera, L'enfant et les sortilèges (The Child and the Spells), was acquired for the 1988 opening of The Contemporary Museum, Honolulu, and was installed in the Milton Cades Pavilion on the grounds of Spalding House.
While open as a museum, the grounds displayed sculpture by Satoru Abe, Charles Arnoldi, John Buck, Mark Bulwinkle, Deborah Butterfield, Gordon Chandler, Jedd Garet, Jun Kaneko, George Rickey, James Seawright, Toshiko Takaezu, Tom Wesselmann, and Arnold Zimmerman.
