La Gemme A Southern Highlands Showpiece For Sale

La Gemme Estate, a grand getaway meticulously reimagined by The Property Stylist founder Kyara Larcombe, has debuted on the coveted Southern Highlands property market with a price guide of $30 million.

Kyara and her husband Clayton, founder of PAC Capital and Pacific Partners, bought the Bowral estate in 2021 and collectively set about curating a stately country compound that would feel at home alongside the heritage chateaux of Europe.

The finance and design duo purchased the 40ha property as a luxury weekender, then in 2024 held their wedding (after eloping in Lake Como, Italy) at the 40ha estate – a glamorous event later covered in Vogue magazine.

Deborah Cullen and Richard Royle of Cullen & Royle are marketing La Gemme through an expressions-of-interest campaign, closing on March 10 at 5pm.

“It is an absolute divine experience to wander around this estate. The detailing and finishes are on another level,” Ms Cullen said.

“Excitingly, we have had some very well-known families reach out to learn more.”

Over four years, Kyara – whose team has styled private homes worth as much as $100 million and iconic venues such as the Sydney Opera House – exercised her design prowess to bring the dream project to life. Alongside Clayton, the globetrotters travelled throughout Europe to gather inspiration and acquire unique antique pieces to furnish La Gemme.

Rather than a renovation, Ms Cullen said the finished result is a custom-made mansion with all the must-haves of the 21st Century.

The brand-new estate was designed for offshore investors and high-net-worth homebuyers, with a focus on architectural excellence and complete privacy.

La Gemme Estate can house up to 24 guests in the five-bedroom main residence and a separate two-bedroom guest house.

In the primary house, each bedroom has its own ensuite, and there is an additional attic suite. There are formal lounge and dining spaces, a study, a library and lift access.

Designer elements include a bespoke marble kitchen with two large island benches, a Lacanche stove, butler’s pantry with integrated appliances, reclaimed French oak floors retrieved from a historic church in Normandy, Joseph Gilles hardware, and 18th and 19th-century French chandeliers and mirrors.

Modern features include a climate-controlled wine cellar, underfloor heating, ducted air conditioning, a Lutron home automation system and security, and an integrated Bose sound system.

La Gemme Estate is also home to a 14m heated swimming pool and spa with a cabana and limestone-paved courtyard terrace, an outdoor fireplace and a wellness centre with a fully equipped gym and sauna.

Gardens designed by Richard Haigh feature a long driveway lined with mature plane trees, an abundance of established Australian natives, and a koi lake. Additionally, DA approval has been granted for a luxury stables complex and covered arena, ideal for equestrian enthusiasts.

The property, which is about 120 kms from Sydney and 185 km from Canberra, is accessed via two gated entrances; either from Range Rd, Mittagong or Kimberley Dr, Bowral.

La Gemme at 31 Kimberley Dr, Bowral is listed with Cullen Royle via an expressions of interest campaign closing on March 10 at 5 pm.

The Sydney developer-builder, which typically retains its projects, is offering 54 residences off the plan on Spencer Street, with prices starting at $3.9 million.

HSN Property Group has launched Maison Jolene in Rose Bay, giving buyers a rare opportunity to purchase off the plan from a developer-builder that has spent more than two decades building a predominantly build-to-hold portfolio in Sydney’s eastern suburbs. HSN values that portfolio at $4 billion.

Located at 2–16 Spencer Street, Maison Jolene comprises 54 residences, including house-sized two- and three-bedroom apartments, sub-penthouses and penthouses. Prices start at $3.9 million, according to HSN, with many residences designed to capture views across Rose Bay, Sydney Harbour and the city skyline.

James Nixon, head of projects at The Rubinstein Group, is handling the sales campaign alongside agency founder Gavin Rubinstein. He says the launch is an unusual opportunity for buyers who have followed the developer’s work.

“HSN is renowned for building entire projects and rarely selling a single apartment to the open market, so Maison Jolene really is a first for potential buyers who have been following the brand across previous projects,” Nixon says.

HSN worked with architecture practice MHN Design Union and interiors studio The Unlisted Collective on the development. A rhythm of arches and deep-set openings gives the building its presence on Spencer Street, while the residences are positioned to make the most of natural light, privacy and outlook. Landscaping frames the arrival and carries through to the shared outdoor spaces.

“Maison Jolene was conceived to bring a touch of European elegance to Rose Bay, drawing on the understated charm of Mayfair and the romance of Paris while remaining grounded in the relaxed character of Sydney’s eastern suburbs,” says Rafi Assouline, founder and director of HSN Property Group.

The apartments were designed with established Rose Bay downsizers in mind. Large kitchens, generous storage and flexible living areas are intended to ease the move from a family home, with layouts that can also accommodate families and professionals looking for more space in an apartment.

The shared amenities are designed as an extension of those homes. Residents will have access to a lounge, private dining room and landscaped alfresco entertaining area. A wellness retreat brings together a magnesium pool, cold plunge, sauna, steam room and heated stone recovery bench, alongside a gym and dedicated space for Pilates and yoga.

Inside the apartments, the curves of the façade recur in the cabinetry and balustrades. Custom wall sconces, tapware and patterned parquetry sit alongside carved marble basins, hammered-glass shower screens and recessed stone niches. Timber veneer wardrobes have leather-clad drawers, while an Art Deco-inspired motif appears in the raised ceiling detail, joinery and built-in velvet bedheads.

“Maison Jolene is at once contemporary and old world, with custom-designed parquetry flooring and an art deco-inspired motif juxtaposing with the curvature of the arched facade, balustrade and internal cabinetry,” Assouline says.

The kitchens bring several of those ideas together in a sculptural, bubble-shaped island. Assouline helped design and engineer the curved form and personally selected the marble, which is bookmatched so the veining mirrors across adjoining pieces.

“With each of our projects, I look for symmetry in design,” he says. “Crafting the apartments is like solving a puzzle of one thousand pieces; one little detail wrong could mean the picture doesn’t translate correctly once it’s finished.”

HSN will develop and build Maison Jolene, overseeing the project from design through to construction. The family-owned company says it has delivered more than 270 homes, has 200 apartments under construction and has a 100 per cent completion record.

“As a private, integrated developer-builder, we maintain close control over every stage of a project,” Assouline says. “We see our projects as collaborative partnerships with our architects, interior designers and specialist trades with whom we have refined a very unique aesthetic, to ensure every detail is considered for those who will live there.”

For Nixon, the developer’s involvement in both design and construction is part of the pitch to buyers. “The attention to design excellence, combined with HSN’s proven track record in delivering ultra-high-end developments, ensures a level of rarity and enduring quality seldom seen in today’s market,” he says.

“To purchase an HSN property is to acquire a property that will not just hold its value but stand the test of time as a timeless piece of Sydney real estate.”

The Spencer Street address puts residents close to Rose Bay’s village cafés and restaurants, foreshore walks and ferry service, with beaches, golf courses and schools nearby. Maison Jolene is now selling off the plan through James Nixon and Gavin Rubinstein.
