Ninah Cummer and Clara Cummer, both now widows, died in 1958. Ninah Cummer left her estate, including her gardens, to the DeEtte Holden Cummer Museum Foundation for a museum to house her art collection. In 1960, the siblings' homes were both demolished in order to build the museum. Clara and Waldo's property was sold and now houses the Northeast Florida chapter of the American Red Cross and the Cummer's education center, Art Connections. Parts of the gardens were also destroyed during this demolition. The new building was designed by Saxelbye and Powell and constructed in 1961. It featured an Art Deco façade and an inner courtyard that was paved with the terra cotta tiles of the Cummers' old roof. One room from the original Cummer home, known as the Tudor Room, was preserved and incorporated into the new museum. The Cummer Museum of Art & Gardens, then named The Cummer Gallery, opened on November 11, 1961.
