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.
Determinations on large scale development projects can be found at the bottom of the article.

154-158 Pacific Parade, Dee Why – DA2025/0024
Determination: Approved
Date determined: 19 November 2025
Determination Level: Northern Beaches Local Planning Panel
Cost of Work: $ 11,034,224
The Northern Beaches Local Planning Panel unanimously approved the proposal to construct shop-top housing at the site where Beach Burrito Co and JB & Sons are.
Council recommended for the application to be approved despite 22 of the 23 submissions being against the development, mainly due to height and loss of views by neighbours.
In January 2025, Harrington Property lodged the $11 million DA – they first purchased the block 154-158 Pacific Parade Dee Why in 2014 for $2.75 million.
The new building will feature nine apartments (three allocated as affordable rental apartments) over three levels, with a ground level for cafes and restaurants.
We covered the DA in detail here, and before anyone cries over the loss of a burrito or burger, both businesses have about another four years on their leases and they may be considered for the new ground-level.
