Overview

The Ultimate Sydney Trophy Asset

"Ellesmere" is a Victorian Gothic sandstone castle, a significant heritage estate in Sydney, meticulously restored for 2026. This grand residence is situated on a sprawling, level 1,201 square meter parcel featuring rare street-to-water access, blending the grandeur of 1880s architecture with modern luxury through a comprehensive $3 million designer transformation.

The property offers a private compound experience with a cinematic arrival via a 75-meter private driveway, ensuring complete seclusion. This exclusive access leads directly to a private boat ramp, providing seamless entry to the pristine waters of Kogarah Bay, a unique feature that distinguishes this estate.

The heart of the home is a world-class kitchen, designed with modern sophistication. It is wrapped in exotic Italian Dolce Vita Quartzite and includes a hidden Butler's pantry. The kitchen is equipped with dual-zone dishwashing facilities featuring two fully integrated Siemens dishwashers, a triple Siemens microwave/oven suite for large-scale entertaining, a Miele zoneless induction cooktop, and bespoke finishes including an integrated Zip Tap and premium brushed nickel hardware throughout.

The residence spans three expansive levels and includes six oversized king bedrooms, providing exceptional versatility for a modern elite family. The ground floor houses a private guest or staff wing with the sixth bedroom serving as an ideal Au Pair suite, live-in quarters, or professional home office, offering privacy from the main family suites. Formal entertaining spaces include a grand dining room with Victorian elegance, accommodating a 10-person banquet table, anchored by an original hand-carved marble fireplace, soaring ornate ceilings, and heritage leadlight windows. The grand ballroom preserves the original Victorian grandeur with twin marble fireplaces and soaring ceilings, designed for world-class events. The master sanctuary features a designer ensuite and a boutique-style walk-in wardrobe with a luxury island storage center.

The wellness wing and outdoor resort area at the rear of the estate is an entertainer's paradise, anchored by a massive 100,000 litre saltwater swimming pool and spa. The wellness center includes a dedicated sanctuary with a six-person traditional sauna and a separate poolside cabana. The attic retreat is a light-filled top-floor sanctuary housing a private gymnasium and home office. Resort-style entertaining is enhanced by a brand-new expansive timber deck, perfect for sunset cocktails overlooking the water, with manicured level lawns leading directly to the water's edge.

Premium features include a 1,201 square meter level land with 75 meters of private access to the boat ramp, a $3 million investment in structural and aesthetic upgrades, a six-person sauna, separate outdoor cabana, and a 100,000 litre pool. The kitchen boasts a full Siemens and Miele appliance suite with Italian Dolce Vita Quartzite surfaces.
