A proposed demolition and rebuild at Bilgola Beach has received approval for a site at 2A Allen Avenue, concluding a multi-year planning dispute marked by objections from nearby residents.
Background To The Bilgola Beach Proposal
The site at 2A Allen Avenue, Bilgola Beach, contains a dwelling originally constructed in 1951. The property was purchased in 2019, and a development application was lodged in 2022 seeking approval for a large replacement home.
That initial proposal attracted objections focused on height, scale and neighbourhood character. It was refused, and an appeal to the Land and Environment Court was dismissed in April 2024.
Revised Application And Court Outcome
A revised development application, DA2024/1708, was submitted on 8 January 2025. The application sought approval for demolition works and construction of a dwelling house including a swimming pool.
Following a deemed refusal, the matter proceeded to court. The appeal was upheld on 16 April 2025, subject to amended plans. The planning register lists the determination level as court and confirms approval status.
The cost of work recorded in the planning register is $4,264,221. Separately, the redevelopment has been described as a $5 million project.
The register also records an exhibition period from 8 October to 22 October 2025, which appears after the determination date.
Design And Amenity Considerations
Objections raised during the process referred to the size of the proposed dwelling, the number of rooms, rooftop recreation areas, privacy impacts from overlooking, and potential loss of sunlight and views. Additional concerns related to excavation depth, landscaping provision and the fit of the development within its surroundings.
Planning arguments supporting the proposal maintained that remaining height exceedances were minor and that similar multi-storey homes exist nearby.
Community Response And Petition Activity
Community opposition included written submissions and petition activity linked to the proposal. A previous petition was reported as having attracted more than 1,500 signatures opposing the development.
Community posts continued to encourage further petition participation and urged an appeal of the court’s approval, with sign-up activity promoted in the Avalon area.
Next Steps
With the appeal upheld, the approval allows demolition of the existing dwelling and construction of the approved design, subject to the amended plans attached to the determination.
