Abadeen secures first approval under low and mid-rise housing policy for Heydon Street, Mosman apartment development

High-end Sydney developer Abadeen has secured approval for one of its latest Mosman projects, one of the first developments approved by Mosman Council under the NSW Government’s Low and Mid-Rise Housing Policy.

The approval represents an important step in delivering well-considered housing next to established village locations on Sydney’s Lower North Shore, in line with the intent of the Low and Mid-Rise zoning framework.

There are currently 13 other sites lodged within Mosman Council under the policy, with Heydon Street among the first to receive development consent.

Abadeen Founder and Executive Chairman Justin Brown said the project reflects a considered and appropriate response to its planning context.

“This approval demonstrates how carefully considered, design-led development can align with the objectives of the Low and Mid-Rise Housing Policy," Brown said.

"The scheme has been designed to respond sensitively to its village setting, with a built form, scale and level of amenity appropriate to its local context. The determination reflects a balanced and considered planning outcome, with Council recognising the capacity for this site to accommodate additional housing within a well-located and established precinct.”

The Heydon Street approval followed extensive consultation with Mosman Council, with Abadeen working closely with Council throughout the assessment process.

The approved scheme comprises 27 residences, with only four per floor, creating a low-density living environment. The building will include four half-floor penthouses designed to capture views across Middle Harbour, Sydney Harbour and the surrounding district. 

The project is expected to appeal to downsizers and owner-occupiers seeking house-like proportions, privacy and local convenience. There will be north-facing Middle Harbour views from the second level upward. It is also just a flat 100-metre walk to Bridgepoint Shopping Centre, which will appeal to owner-occupiers and in particular downsizers.

Two-bedroom residences are expected to be priced from $1.99 million when sales launch later this year.

Joe Tack, CEO at Abadeen, said the outcome reflects both the quality of the site and the broader need for well-located housing.

“This is a highly considered site within a highly established local setting, offering elevated views and strong connectivity. The project has been designed to respond to that context, delivering a scale and quality of housing aligned with both the planning framework and evolving market demand.”

“This approval is particularly significant in the context of Mosman, where new housing supply has historically been limited. While it represents the first approval of this scale in Mosman to be achieved in over 50 years, it is importantly located within a well-established residential location, in close proximity to the established commercial amenity of Spit Road and Mosman Village. It reflects strong confidence in Abadeen’s approach to design, delivery and community integration, while contributing to the delivery of much-needed housing in a highly constrained market.”

Abadeen has an established track record across Sydney’s Lower North Shore, with recent completions including KOYO in Crows Nest and ENSO in Neutral Bay.

In Mosman, Abadeen recently completed The Hampden, with Mosman Residences on the corner of Spit Road and Clifford Street scheduled for completion later this year. Construction has also commenced at Burran Residences, comprising three full-floor ultra-premium homes positioned just 50 metres from Balmoral Beach, with residences expected to achieve prices in excess of $20 million. Two further projects are also progressing through planning within the local government area.
