Later, Pichileminian Roberto Álvarez decided to run a discotheque called "Master" in the same place, while at the same time, there was a "grill bar" called "Wa-Na" in another room; both businesses operated until the 1990s. The condition of the building gradually deteriorated, and its use became restricted. During the administration of Mayor Julio Waidele Wolff (1981–1983), an attempt was made to buy the building with municipal funds; however, Waidele was not allowed to complete the purchase because the price of eight million pesos (approximately US$16,000) was "too high for the municipal budget, and would leave many things without financing." The building would finally be purchased in 1995 by Mayor Orlando Cornejo Bustamante with the support of the Pichilemu City Council, then composed of Aldo Polanco Contreras, Jorge Vargas González, Mario Bichón Cáceres, Mariano Polanco Galarce, and Raúl Tobar Pavez, for 30 million pesos (approximately US$60,000). In 1987, after the re-inauguration of another work of Agustín Ross, the Ross Park, a request was made to the National Monuments Council that both the park and the former casino be declared "Monumentos Históricos" (National Monuments); they were so designated on 25 February 1988. After the former casino was purchased by the government of Pichilemu, the building was used to hold meetings, exhibitions of paintings, sculptures, theater, and for launching books. In 1997, the Club Aéreo de Pichilemu (Aero Club of Pichilemu) requested the building to host the fiftieth annual reunion of the Air Federation of Chile. Permission was granted, but the Club Aéreo had to purchase toilet fixtures, as the ones in the building were seriously damaged. This prompted the government of Mayor Jorge Vargas González (1996–2007) to begin restoring the deteriorated former casino, but it was not until 2004 that the Regional Government of Libertador General Bernardo O'Higgins Region approved financing for a restoration design study. The study by the Department of Architecture of the Ministry of Public Works began in 2005 and lasted until mid–2006. Afterwards, on 15 December, Intendant of Libertador General Bernardo O'Higgins Region Héctor Leiva Polanco unveiled to the community of Pichilemu the design and announced that he would present a financing proposal during the next year to the Fondo Nacional de Desarrollo Regional (National Fund of Regional Development).
