Just 20 months later, the home is back on the market with a guide price of $12.8 million and will be auctioned on August 29th. It seems their dog was to blame!

The couple has instructed the brokers who sold them 8/20 Carlisle Street, Andre Frack, director of Richardson & Wrench Bundy Junction, and Julian Hasemer, founding principal of 1st City, to sell the Carlisle Street apartment again.

As Frack says, "It's a towering oasis with breathtaking panoramic views, complemented by a serene and undisturbed ambiance that is truly irreplaceable."

The three-bedroom, three-bath duplex mansion with a five-car garage was designed by Poco and features spacious indoor and outdoor spaces, as well as a wrap-around terrace.

Their co-broker recently sold an off-plan garden condo with a pool in Luigi Rosselli's latest Bellevue Hill project.

Relisted and ready for new custodians, the Marbella penthouse's elevated position offers five-star panoramic views of Sydney Harbour and the city's skyline from most rooms, as well as a large alfresco space with a motorized pergola and Bromic external heating for four-season entertaining.

The spacious living room is enclosed by floor-to-ceiling glass to maximize the world-class views, and the gold kalakata marble kitchen features a gas cooktop, large island stools and sleek black hardware.

There's even an integrated marble bar, ideal for cocktail parties.

The Penthouse, the top floor apartment in a boutique complex of eight residences, features spacious bedrooms including a master bedroom with private balcony and an additional mezzanine bedroom or home office with skylights, two en-suite bedrooms and a master bathroom, as well as zoned reverse-cycle air conditioning and outdoor heating.

On the title, the property also includes two double lock-up garages and a single lock-up garage located in the secure basement, providing plenty of space for a car collection or boat.

With a residents-only pool, sauna and gym, Marbella is also close to harbour beaches, ferries, buses, cafes, fine restaurants and plenty of green space at Lyne Park and the Royal Sydney Golf Club.
