“Coveted Sydney Mansion sets new price record!”

“Sydney’s North Shore has just hit a new price record in the vicinity of $50m with the sale of 3 Kirkoswald Ave after less than a week on market”

High above Mosman’s headlands, where the harbour stretches unbroken to the horizon, stands a residence that redefines prestige. Designed by Susan Rothwell and set upon more than 2,200 square metres of level land, 3 Kirkoswald Avenue commands the suburb’s highest ridge and is a landmark of proportion, privacy and grace.

Commissioned by Australian art collectors, the home embodies both sanctuary and gallery. Through glass, marble and shadow, light pours across sculptures and hallways, each corridor revealing a new perspective on water, art and air. The vast atrium opens to a courtyard framed by palms, where reflections shift between sculpture and sea — a living composition of movement and stillness.

Gardens by Will Dangar flow around terraces designed for entertaining, while a 20-metre wet-edge pool dissolves into the ocean’s blue. Inside, grand volumes and intimate moments coexist with soaring ceilings, Italian marble dining, and tranquil bedrooms where the harbour becomes part of the artwork itself.

Every detail speaks of discernment: underfloor heating, a private lift, a wine cellar, and bespoke finishes that reward a lifetime of curation. Even in a suburb defined by beauty, this estate stands apart —a rare convergence of architecture, art and landscape —now quietly setting a new benchmark for Sydney’s North Shore. For privacy reasons, we can’t publicly show this film.
