Alon Kowen, MD of Auction Alliance Cape Town, said there had been particularly high levels of interest from both local and foreign clients.

"This is only the second auction of the year in Plett. Property in this town, particularly blue-chip real estate such as this, is in great demand," Kowen said.

The property measures 1 855m2 and is in the town's prime business district.

The current tenants include high-profile retailers such as Steers, Markhams and Caltex, generating an annual rental income of about

R645 000. The site, 21 Main Road, can be viewed by appointment.
