The Government of the Soviet Union purchased the house from Castroviejo in August 1975 for US$1.6 million, and began renovation work on the building. The Soviets also spent US$400,000 on the neighbouring townhouse and US$100,000 for half a driveway which was owned by the neighbouring Convent of the Sacred Heart school. William Gleckman, who was responsible for renovations work on the building, noted that Mr. Myshkov, the Soviet Consul-designate, admired the building as it reminded him of imperial architecture in Russia. Gleckman installed new electrical wiring, a theatre and air-conditioning. The Soviets also received permission to install a large wrought-iron gate around the mansion and closed-circuit cameras to watch over the street in front of the building. A total of US$500,000 was spent on renovations before the Soviets were ordered to leave in 1980.
