Abadeen approved for Mosman's priciest apartments
Lower North Shore developer Abadeen has secured development approval for its ultra-luxury residential project on the dress circle Burran Avenue.
The project, just 50 metres from Balmoral Beach within MOSMAN’s prestigious Golden Triangle, will commence construction in early 2026, following the successful completion of its nearby Hampden MOSMAN project.
Lodged in April 2025 and approved in September 2025, the development will comprise three whole-floor residences, each designed to capture panoramic harbour views through Sydney Heads.
Set on an elevated 550 sqm corner site at The Junction of Burran Avenue and Stanton Road, the building has been designed to sit within Balmoral’s natural slope. The façade mixes stone and metal cladding with angular forms, while oversized terraces and full-height sliding doors create a connection between interior living spaces and outdoor entertaining areas.
The delivery team from Abadeen’s Hampden MOSMAN project, which includes construction company Reform Projects and interiors company Mathieson, has been retained to bring the same level of execution and craftsmanship to Burran Avenue.
Platform Architects has been appointed project architect, bringing extensive experience from recent luxury residential projects in Manly, Fairlight and Freshwater.
Justin Brown, Executive Chairman and Founder of Abadeen, said sites of this calibre, this close to Balmoral, are incredibly rare.
“Burran Avenue is an extraordinary site; its location, its scale and its outlook make it truly one of a kind. Receiving DA approval marks an exciting milestone for Abadeen."
"We’re proud to be moving forward with an exceptional team to deliver a project that will set a new standard for ultra-luxury living on Sydney’s Lower North Shore. Construction is planned to commence in early 2026, and interest is already strong from discerning local buyers who recognise the uniqueness of this address."
Brown anticipates prices will set new MOSMAN benchmarks above $20 million. Sales are expected to launch in March 2026.
