Mosaic Property Group’s latest Burleigh Heads development is closing in on a full sell-out after recording more than $180 million in sales within months of launch.
The $200 million beachfront project, Josephine by Mosaic, has seen strong early demand, with the developer now bringing forward construction as remaining stock tightens.
Positioned at 166 The Esplanade, the project marks Mosaic’s fourth beachfront address along Burleigh’s tightly held coastal strip and its fifth in the suburb, reinforcing ongoing demand for design-led, high-end residences in scarce locations.
Designed in partnership with Sydney-based EMK Architects, Josephine comprises 30 half- and full-floor residences across 18 levels, with some residences approaching 500sqm and prices reaching up to $13 million.
A limited number of residences remain, with pricing from $4.5 million.
The project was initially released off-market in late 2025, with early buyers including a mix of local owner-occupiers and investors, many already familiar with Mosaic’s track record.
Mosaic Founder and Managing Director Brook Monahan said the response reflects a growing focus among buyers on quality, certainty and long-term value.
“The market’s response reflects the value of staying closely aligned with people and place,” he said.
He added that the decision to accelerate construction was driven by internal capability and planning rather than short-term market conditions.
“The volatility of recent years… has reaffirmed the importance of the disciplines we have always prioritised,” he said.
The performance of Josephine comes amid continued depth in the Gold Coast’s luxury apartment market, where demand is increasingly concentrated in tightly held beachfront locations.
Completion of the project is expected in mid-2028.

At the northern tip of Point Piper, hidden from the street and positioned directly on Sydney Harbour, “Radford” combines cinematic views, rare waterfront access and a fascinating connection to one of Australia’s most storied estates.
The five-bedroom residence occupies land once belonging to Paradis Sur Mer, the celebrated three-block waterfront estate that made Australian property history in 1982. The original mansion became the country’s first home reported to have sold for more than $5 million—and may also have inspired one of its fastest and most profitable resales.
Property developer and yachtsman Bernard Lewis purchased the estate at auction for $5.25 million, only to sell it within hours to English betting magnate and thoroughbred breeder Robert Sangster. Lewis reportedly made a $500,000 profit in the process.
Sangster renamed the property Toison D’Or—French for “Golden Fleece” and the name of one of his racehorses—and established it as a Sydney base with his then-wife, Susan. The estate subsequently changed hands and identities again, becoming Paradis Sur Mer, or “Paradise on the Sea”, during Susan’s marriage to financier Sir Frank Renouf.
After another headline-making sale near the peak of Sydney’s late-1980s property boom, the original mansion was eventually demolished and the waterfront holding subdivided. “Radford” now stands on one of those prized parcels, carrying a thread of that extraordinary history into the present day.
Harbour views take centre stage
Designed by award-winning architect Victor Berk and constructed in the early 1990s, the three-level modernist residence has been planned around its exceptional position.
Panoramic views stretch from the Sydney Harbour Bridge across Shark Island and Rose Bay to Manly. A prized northerly aspect fills the home with natural light, while bedrooms and living spaces open to decks, balconies and terraces overlooking the water.
The main living areas flow to a broad alfresco entertaining terrace, sunny swimming pool and level harbourfront lawn. Beyond the garden, a private jetty completes the quintessential Sydney waterfront lifestyle.
Inside, generous proportions make the home equally suited to private family life and large-scale entertaining. The formal dining area can accommodate up to 14 guests, while a Gaggenau-appointed kitchen incorporates an island, walk-in pantry and casual breakfast area opening to the poolside deck.
A fireplace anchors the principal living space, complemented by high ceilings, travertine floors and expansive glazing that keeps the harbour present throughout the home.
A private sanctuary on every level
The main bedroom is accompanied by two walk-in wardrobes, a sitting area and an ensuite featuring a spa bath, separate shower and twin basins. Three further bedrooms each have an ensuite, while a gym with its own kitchenette, built-in storage and bathroom can serve as a fifth bedroom or private guest retreat.
Additional spaces include a fitted home office, an upper-level family area, sauna, two powder rooms and a substantial laundry. A lift connects all three levels, and the central staircase sits beneath an atrium-style glass roof fitted with an electric retractable blind.
Ducted and zoned air-conditioning, extensive storage and a security alarm add everyday practicality. Internal access leads to an oversized secure double garage, with additional driveway parking.
Set in an elite cul-de-sac on one of Australia’s most prestigious waterfront streets, “Radford” is close to Lady Martins Beach, Prince Edward Yacht Club, the Royal Motor Yacht Club, Rose Bay’s marinas and leading schools. Double Bay’s restaurants, boutiques and village amenities are only minutes away.
It is an exceptional harbourfront residence in its own right—but its connection to the record-breaking Paradis Sur Mer estate gives it a place within the wider story of Sydney real estate.
