Two abandoned palatial mansions built by a Chinese billionaire for $75million have been sold just days before going to auction.

The sprawling side-by-side mansions in the southern Perth suburb of Banjup, 30 minutes from Perth’s CBD, sold for an undisclosed sum.

The property was left incomplete and has never been lived in after the owner, Chinese education billionaire James Tan, returned to China for family reasons.

Spread across 4.5 hectares of land, the two homes have a combined space of 10,000 square metres.

The striking properties feature more than 80 rooms including 20 bedrooms with ensuites, several kitchens with private dining halls, a library, multi-functional theatre, museum, and multiple large conference halls.

There are also swimming pools and four courtyards, designed according to Feng Shui teachings.

Constructed between 2014 and 2017, the complex cost $75million to build and was named Chinese Style Confucius Mansion by its owner.

It was designed in a fusion of Jingpai and Huizhou architectural styles, with one home designed for day-to-day living and the other for entertainment.

The complex is set on Lot 88, a number symbolising fortune and good luck in Chinese culture.

One of its buildings is adorned in bright red and yellow which are lucky colours in Chinese tradition.

Effective Property Solutions’ head of international markets Leon Siew said he had received great interest from the Chinese community.

'There’s a reason why there’s been so much interest from Chinese buyers – they actually like the uniqueness of the design and architecture, it reminds them of home,' Mr Siew said.

'While somewhat dilapidated, this Chinese-style mansion is majestic. It’s 90 per cent completed, there’s just a few cosmetic finishes that need to be done,' selling agent Leon Siew said

Mr Siew said the owner told him he had lavished $75million on the homes including land and statues, however the statues had been stolen.

Around $1.5m was spent just on the rose garden, which has since died.

Estimates to complete the building's fit-out range between $2 million and $5 million.
