For some time, Parkveien 45 served as the residence of the Norwegian Prime Minister. Originally the building was a private property belonging to Frederik Sundt who was a businessman involved in the import of paraffin oil, and for this reason, the house is also known as "Villa parafina." In 1896, the government of Norway purchased the villa and between 1898 and 1908 it served as the residence of the country's Prime Minister. Between 1908 and 1961, the villa served as the residence of the minister of foreign affairs, and thereafter it was converted into a government representation house. The villa has played a vital role in the history of Norway because it was in the villa where the negotiation of the country's independence was held in 1905.
