Public records show the seller is William Deague,chief executive of property developer Deague Group,who bought the block four years ago.
When contacted,Mr Deague confirmed the sale of his home,which he built with wife Nat who designed the interiors,but declined to comment on the price,the identity of the buyer or any other details.
“We are very pleased with the result and looking forward to the next project,” he said.
A source familiar with the transaction but not authorised to comment pointed to Marshall White’s Marcus Chiminello as the agent. Mr Chiminello confirmed the sale but declined to comment on the price or the identities of the seller or buyer.
It is likely to be among the top few sales in Toorak. Chemist Warehouse boss Sam Gance paid $43.1 million in the suburb last year,while in recent years tech entrepreneur Ruslan Kogan paid $38.8 million and a fire-damaged house fetched $38 million.
Settlement will reveal the price,which two sources with knowledge of the off-market deal put in the high $30 million range.
