Spring has sprung early in Mosman, with this stately Clifton Gardens residence on the market for the first time in 43 years.

Just listed by Ray White Mosman’s Geoff Smith and Richard Harding, the majestic 1921 manor is already turning heads, with cashed up Sydney buyers ready to dig deep, for what is said to be “a once-in-a-lifetime” opportunity.

Set on 1532sqm, the property is the largest parcel of land on Kardinia Rd - and has been lovingly looked after by one family for more than four decades.

An immaculate nod to the past, agent Geoff Smith says the gracious home is unique in every way - and has been respectfully updated and extended, without losing any of its historic grandeur.

“I love the land size, the privacy, the position and aspect of the property – and the potential it offers,” he tells Mosman Collective.

“It is the perfect family home, proved by the fact that only two families have owned it since 1921. 

“It really is a very special residence.”

Named “Roumalla”, 23 Kardinia Rd is a once-in-a-lifetime opportunity to purchase an oversized landholding upon two separate titles, with potential to develop.

“The real advantage of ‘Roumalla’ is that it is a double block with a 30-metre frontage, whereas some other blocks of similar sizes are narrow and deep,” Mr. Smith said. 

“This allows for space on all sides of the home.”

Level, landscaped grounds surround the five-bedroom beauty queen and are ideal for growing families who love to entertain. Flooded with natural night, the home also enjoys northern sun through its casual dining and living spaces.

Stunning bay windows, a grand hallway, veranda and ornate ceilings define this property as a classic Mosman home, “with the added bonus of its beautiful inground pool – plus the option of Chowder Bay,” Mr. Smith says.

“It really is a residence that ticks all the boxes.” 

23 Kardinia Rd, Mosman is open for inspection Wednesdays and Saturdays: 12:00-12:45pm.

PRICE GUIDE: $10.5m - $11.5m
