Leading property developer, Abadeen has officially completed its latest luxury residential project, Hampden, in Mosman’s prestigious Lower North Shore, with just one exclusive north-facing whole-floor garden residence remaining, capturing Middle Harbour views.
Set within Mosman’s coveted Golden Triangle, Hampden represents a truly rare opportunity; brand-new, completed luxury residences of this calibre and location are seldom released to the market. Positioned on the edge of the new Low to Mid-Rise Housing zone, the site is surrounded by properties to the north and east that are subject to lower height limits, ensuring that the residence’s sweeping views remain protected.
Located on street frontages 1A Hampden Street and 8 Warringah Road, Mosman, ideally positioned between Balmoral Beach, Chinamans Beach and Mosman Village, Hampden is a boutique collection of only three architecturally designed, full-floor residences that blend timeless sophistication with contemporary design.
The final apartment, priced above $13m at Hampden is a full-floor 243sqm ground floor residence featuring three bedrooms, two bathrooms and a two car garage, offering the proportions, privacy and liveability of a freestanding home, without the upkeep.
Designed by Mathieson Architects and built by Reform Projects, this home features expansive living and dining areas, soaring ceilings, and a sun-drenched private terrace with sweeping north-facing views over Chinamans Beach and Middle Harbour. With a private lobby, lift access, and a secure double lock-up garage, this residence offers refined simplicity in one of Sydney’s most tightly held harbourside suburbs.
With strong buyer demand and limited supply of premium, low-maintenance homes on Sydney’s Lower North Shore, the final residence at Hampden presents a rare opportunity to secure a brand-new, move-in-ready home in one of the city’s most exclusive enclaves. The new owner could be settled in by Christmas, perfectly timed for a quintessential Sydney summer by the beach.
Justin Brown, Executive Chairman and Founder of Abadeen, said:
“Hampden is a true reflection of Abadeen’s vision — boutique in scale, enduring in quality, and deeply attuned to how people want to live today. We’re so pleased with the result that we’ve engaged the same team for our upcoming prestige development at Burran Avenue, just moments from Hampden.
Opportunities to secure a brand-new residence of this calibre are incredibly rare. We encourage interested buyers to get in touch ahead of our first open for inspection campaign launching on 25 October 2025.”
The Perfect Entertainer
The residence features expansive indoor–outdoor living spaces anchored by a stylish fireplace, perfect for year-round entertaining. From the living areas and terrace, a cinematic panorama unfolds — sparkling harbour waters, yachts gliding by, and golden headlands catching the afternoon light. It’s a view that shifts throughout the day, offering moments of quiet beauty and dramatic sunsets.
Premium finishes include oak timber floors, Astra Walker aged iron tapware & accents, state-of-the-art Sub-Zero, Wolf and V-Zug appliances, including an enviable full height wine fridge. The luxe master retreat is a true sanctuary, complete with generous walk-in robes and a stunning ensuite. Every detail has been considered to evoke a sense of timeless luxury and understated grandeur.
Unmatched Lifestyle Offering
Perfectly positioned near some of Sydney’s leading schools, Hampden offers residents easy access to harbour beach walks, boutique shopping, fine dining and entertainment, and express transport to the CBD. From your front door, it’s just moments to the calm waters of Balmoral and Chinamans beaches, Mosman Village’s boutique charm, and Sydney’s vibrant harbour lifestyle — all wrapped in a rare sense of seclusion and prestige.
The first open for inspection is Saturday, 25 October 2025. For enquiries regarding the final remaining residence, please contact Adrian Bridges on 0414 616 101 or visit www.hampdenmosman.com.au.
