was the home of statesmen and nation-builders, but it will be remembered for a R140m spat involving a swimwear model and her businessman father.
This week the "battle for Zonnekus" ended in an auction after the 10-year spat had gone as far as the Constitutional Court.
The mansion, commissioned in 1929, once attracted values of up to R100m. On Thursday it attracted a highest bid of only R15.5m.
The auction marks the end of an era for businessman Gary van der Merwe and his model daughter, Candice, who were central to the tug-of-war over the property.
They and their legal representatives made hundreds of court appearances in a fight with the South African Revenue Service (Sars) over a $15.5m (about R140m in 2012) payment to Candice - allegedly a gift from her "admirer", former Lebanese prime minister Saad Hariri.
The payment was flagged as suspicious by the Financial Intelligence Centre (FIC).
This promoted a Sars investigation and a subsequent tax bill, which the Van der Merwes challenged.
The Van der Merwes began several court applications against the liquidators of Gary van der Merwe's assets, which are held by Zonnekus Mansion (Pty) Ltd.
On February 5, the Constitutional Court dismissed Van der Merwe's attempt to challenge a high court order evicting him from Zonnekus, the Milnerton, Cape Town, beach home he had occupied for almost 20 years.
