The Mutual Building (Afrikaans: Mutual Gebou), in Cape Town, South Africa, was built as the headquarters of the South African Mutual Life Assurance Society, now the "Old Mutual" insurance and financial services company. It was opened in 1940, but before the end of the 1950s—less than 20 years later—business operations were already moving to another new office at Mutual Park in Pinelands (north east of the city centre); since then Old Mutual has become an international business and their present head office is in London.
