Ballarat-born fashion designer Rebecca Vallance lists six-level mansion with $35m price hopes

Rebecca Vallance has listed her glamorous Mediterranean-inspired mansion in an exclusive harbourside pocket favoured by the likes of fellow Australian fashion designer Nicky Zimmermann.

The palatial nine-bedroom, six-bathroom house in Vaucluse spans six levels, with views across Sydney Harbour.

Vallance, who was born and raised in Ballarat launched her fashion label in 2011.

She built the sprawling home with her financier husband David Gasan after purchasing the block in 2018 for $4.45 million and demolishing the two-storey house on the site.

Designed by architecture firm Archer Design, the show-stopping home is described on Biller Property agent Paul Biller's listing as a "newly completed, resort-style masterpiece" that epitomises "luxury family living and grand-scale entertaining in a prestigious Vaucluse address".

"Designed with a perfect north-to-rear aspect, the residence commands sweeping Sydney Harbour views across stately, European-inspired manicured gardens," the listing reads.

"Every detail has been meticulously curated, from globally sourced design elements and soaring ceilings to walls of glass and cutting-edge lighting innovations."

A price guide is not published on the listing but reports suggest it could fetch between $25 million and $35 million, up to four times higher than the $8.8 million median house value in Vaucluse.

Reminiscent of a Mediterranean villa, the concrete structure features stone cladding, curved edges and cascading gardens.

In 2021, Vallance, whose designer clothes have been worn by the likes of Princess Beatrice, Nicky Hilton, Sharon Osbourne, and Naomi Campbell, told Domain of her plan to create a home design with a mix of "modern and classic architectural style".

A grand entrance foyer has sweeping harbour views and a commercial-grade lift servicing four levels.

The master suite has dual dressing rooms, his-and-her marble bathrooms, and a private terrace with harbour views.

Every bedroom is oversized, including two guest rooms with ensuites.

All the bathrooms are finished in natural stone, complete with underfloor heating and heated towel rails.

An elegant formal dining room with a bar has seating for 16 people and features statement chandeliers and coffered ceilings.

The open-plan living has a fireplace and lounge zones that open to the outdoor terraces overlooking the gardens.

At the centrepiece of the house is the luxurious kitchen with a marble island, custom joinery, integrated refrigeration and dishwashers, premium appliances, and a separate butler's preparation kitchen.

Why have one kitchen when you can have three?

Two additional entertainer's kitchens on the lower levels are equipped with Miele pyrolytic, speed and steam-combination ovens, plus three ice makers.

Other property features include a leisure wing with a cinema, a wine cellar, a library and a wellness zone with a gym, an infrared sauna and an ice bath.

There is also a resort-style pool and a ground-level retreat with an integrated barbecue, a wood-fired pizza oven and a grand landscaped garden.

Ballarat-born Vallance's luxury fashion brand debuted in Paris and quickly secured Harvey Nichols as a stockist.

As the brand's global presence grew, she returned to Australia and launched the brand locally in 2012.

The brand's collections, which include ready-to-wear, bridal, denim and occasion wear, are stocked by global retailers such as Net-a-Porter, Mytheresa, Selfridges, Saks Fifth Avenue, Neiman Marcus, Harrods and Revolve.

Vallance is not the only high-flying fashion designer spending up big in Vaucluse.

Nicky Zimmermann, co-founder of the label Zimmermann, paid $59.5 million for a three-storey waterfront home in the suburb in 2022.

Set on almost 1700 square metres, the six-bedroom, nine-bathroom home includes formal and informal living and dining rooms, a rumpus and billiard room and a cellar.
