Storage space is at a premium for many inner-city apartment dwellers.
So Rockwall Apartments, a residential building at Potts Point, looked at its basement garage for vacant spaces within the common property.
At a private auction restricted to people who owned apartments in the Mirvac-built high rise, the body corporate auctioned off seven storage spaces last month.
NSW Title records reveal buyers included David Jones boss Paul Zahra, who spent $28,000 on a two-square-metre basement storage space.
His upstairs apartment with car space cost $1.7 million in 2007.
