A luxury mansion worth $51.8 million has been bought by a businessman from China whose name has not been revealed in one of the largest real-estate deals ever in British Columbia, Canada, Xinhua News said on Thursday.

This 25,000-feet mansion at 4785 Drummond Drive with manicured gardens, flowing waterfalls and winding pathways lead to expansive lawns, a grass tennis court, sports court, a separate guest house and self-contained studio with office and private quarters in an area spread over 1.09 hectares in prestigious West Point Grey, a luxury residential complex in Vancouver.

The mansion is known to be a vacation home for Don Mattrick, the CEO of Zynga, a provider of social game services.

According to Xinhua, the new owner has an investment company in Vancouver, and closed the deal in Dec without involvement of a property agency.

Last year, the mansion was listed on Malcolm Hasman, a property agency. It declined to answer details about the mansion.
