Manly Observer provides a weekly summary of development applications lodged with Northern Beaches Council in the last week.
While every effort has been made to accurately represent the development applications, we recommend clicking the link (the DA number in the heading) which will take you to the relevant council page with detailed information.
Where exhibition periods have not yet been determined at the time of publication, Council is still gathering the required documention needed before notifying relevant parties. Once the exhibition period opens, there will be a link on the DA page for submissions – please refrain from submitting prior to this link becoming available.

159-167 Darley Street West, Mona Vale – SSD-91496958
Exhibition Period: 20/01/2026 to 02/02/2026
Cost of Work: $94,694,933 (ex GST)
The State Significant Development Application (SSDA) – which bypasses Council – will include the construction of three six-storey residential flat buildings. There will be 82 apartments, including 10 affordable apartments. There will be separate lobbies, communal open spaces and the construction of a one to three storey basement car park for 164 cars, including 156 for residents, eight accessible spaces, two motorcycle spaces and 27 bicycle parking space.
The site is located within 400m to 800m of the Mona Vale town centre (you can read more about the Low to Mid Rise Housing Policy here). While the zoning allows for a maximum height of 17.5m, the developers opt-in to affordable housing allows them additional height. Therefore, the development’s height will be 21.175m.
There was also an issue with density which has now been resolved. In April 2025, an amendment to the Pittwater LEP 2014 was finalised, which rezoned the site from R2 Low Density to R3 Medium Density. However, the amendment did not abolish the restriction of dwelling density control (this provides a limit of one dwelling per 200sqm, which restricts the site to 30 apartments). In September 2025, the restriction was removed, allowing for more housing density.
