In 1974, Concepción Teus opted to sell the mansion to First Lady
Imelda Marcos, the wife of then-President and dictator
Ferdinand Marcos, Sr. She engaged interior designer Ronnie Laing and antique dealer Viring de Asis to renovate the Teus Mansion as a guest residence. The mansion is one of the
Marcos mansions and was acquired through ill-gotten wealth during the Marcos dictatorship. Notable guests at the Teus Mansion included the Italian-American socialite
Cristina Ford, who was close associate of Imelda. During the refurbishments by Laing and de Asis, the former dining room has been divided into two bedrooms, and partitions were removed in another bedroom to create a spacious living-dining area. Bathrooms and closets have been cleverly added, concealed behind cabinet fronts. The original downstairs carriageway now serves as an entrance hall. The remainder of the house has been transformed into 12 bedrooms, supplementing the existing five upstairs, giving the old home a total of 17 bedrooms. It also features a large living-dining area, which previously showcased antique European silverware, including works by renowned 18th and 19th-century silversmiths such as
Paul de Lamerie and
Paul Storr. The mansion also housed several paintings by the American artist
Grandma Moses, large vases from the
Qing Dynasty, and cabinets containing porcelain and ivory ornaments. Many of these items were reportedly gifted to the Marcoses on their 25th wedding anniversary in 1979, yet were actually purchased by Imelda using funds
acquired through illicit means during the dictatorship. Following the demise of the Marcos dictatorship in 1986, the Teus Mansion and other properties within the
Malacañang Palace complex became possessions of the Philippine Government, with restricted access to the public. Some European silverware from the Teus Mansion came under the custody of the
Presidential Commission on Good Government (PCGG). Subsequently, the silverware were predominantly auctioned at
Christie's in New York on January 10, 1991. == Reopened as the Presidential Museum ==
