Rocabella at 120 Hedges Ave, Mermaid Beach

A Brisbane penthouse owner has dropped $8m on a yet-to-be-built luxury beachside home on the Gold Coast.

The off-the-plan sale is a coup for high-profile developers Graya, who made their name building jaw-dropping mansions for celebrity clients including ex-footballer Darius Boyd and his influencer wife Kayla.

Graya director Rob Gray said one of two residences in a duplex under construction on Mermaid Beach’s Hedges Ave, known as Billionaire’s Row, was snapped up within 24 hours of launching to market.

The deal was handled by WHITEFOX agent, Nic Whitehead. Named Rocabella, the project’s northern residence, Bella, was the buyer’s pick.

Gray and his wife Meghan, but Mrs Gray is holding firm, reluctant to let go of their own future holiday hideaway.

Mr Whitehead said the listing created an instant stir among buyers “actively searching for a Graya product”.

“A lot of people are dreaming of a beautiful holiday house on Hedges Ave, and owning a Graya home is certainly bragging rights as the recognition of the quality and uniqueness of the brand is unbelievably strong,” Mr Whitehead said.

“That exclusivity is driving demand, and with this product we managed to achieve a really strong price for the area that definitely lifts the bar for a non-beachfront property.”

“Given how Bella has performed, we are still fielding expressions of interest on Roca, the remaining property.

“The biggest headache I have is trying to convince Meghan to let it go,” he said.

Mr Gray said they were “on the fence” about whether to sell.

“Meghan really wants to keep it and Nic is really encouraging a sale. It’s a tough one – it could even be the hardest decision of 2025.”

The couple recently collected $11m from the sale of Dune, a spectacular Moroccan-inspired mansion at Burleigh Heads, also built by Graya, which was originally intended as their dream family home.
