Inside the R1billion-plus Abu Dhabi mega-mansion

A luxury mansion on the shores of Saadiyat Island in Abu Dhabi has sold for a whopping Dh400 million ($108.9 million) - that's more than R1 billion.

This makes it one of the most costly residential deals in the emirate, according to Aldar, the master-developer of Saadiyat Island, Gulf News reported.

The eight-bedroom mansion is part of Faya Al Saadiyat, a beachfront community located on one of the last remaining villa plots on Saadiyat Island.

"Recognised as the crown jewel of Abu Dhabi’s luxury real estate, Saadiyat Island continues to attract homebuyers and investors from around the world," said Jonathan Emery, CEO at Aldar Development.

"The sale reflects the sustained growth of Abu Dhabi’s luxury real estate market."

The master-built mansion is located directly on Saadiyat Island’s beach and within the Saadiyat Beach Golf Club, and boasts the largest allocation of space on the island, spanning 6,561 square metres.

The development company said the sale reflected the growing demand from high-net-worth buyers, long-term residents and international investors.

Foreign residents accounted for 86 percent of buyers who were mainly nationals of Russia, France, the UK, China and the US.

Instagram comments included wry references to how the mansion was built for the super-rich by poorly-paid migrant labourers, while most were light-hearted.
