Chinese firm Bridge Capital and Australian iProsperity Group made a historic offer to buy the 333 Kent Street office tower in Sydney's Central Business District for A$88,888,888.88.

The investors will develop the property into a residential building and a high-end hotel, capitalizing the view of Darling Harbour. The 24-level high-rise building will be able to accommodate approximately 179 hotel rooms and 69 residential apartments, according to the Daily Mail.

The location lies in the heart of Sydney's busy Western Corridor, according to the Sydney Morning Herald. The new business will benefit from the completion of Barangaroo and the International Convention Center.

Vince Kernahan, one of the agents from Colliers International, the real estate broker handling the sale, said the property attracted nine suitors and all exceeded the expectations of owner Maville Bay Group.

"Interested parties were predominantly residential and hotel developers with two groups looking to "landbank" the building," he said.

In Chinese, the number eight is not only considered the luckiest number but also its pronunciation "ba" sounds like the word for prosperity "fa," according to Stuff.

"This is not the first time that Chinese buyers have chosen to offer a price that includes numbers that are considered lucky," Kernahan told BBC.

"The buyer's offer was very close to several other offers. They just chose these numbers for luck and as it turned out their luck was with them."

Maville Group bought the building for $47.75 million in 2012. The company gained approval to develop the property into a residential tower with serviced apartments; however, the Chinese-backed firm faced difficulty transferring funds after increased capital restrictions in China. As a result, it decided to put it back on the market to cash in on premium returns, according to the Financial Review.
