Hidden throughout the suburbs of the Northern Beaches are wonderful examples of mid-century and modernist buildings, both commercial and residential.
Northern Beaches Council is undertaking an important initiative to identify and protect significant examples of modernist architecture across the Northern Beaches, with input from the local community.
GML is working with the Council to deliver the Modern Architecture Study to identify notable Modernist and Mid-Century Modern buildings on the Northern Beaches.
The Council’s existing heritage list is dominated by examples from the Victorian, Federation and Inter-War years. This study aims to rectify this gap by ensuring that significant Modernist-era buildings are identified and protected through heritage listing.
The study includes the preparation of a thematic history of modern architecture on the Northern Beaches, alongside the identification and assessment of locally significant examples of the movement. It is supported by a grant from Heritage NSW.
A public call for nominations of modern architecture buildings was held between May to June 2024. GML and the Council then reviewed all submissions against agreed criteria and consulted directly with the owners of properties prioritised for heritage assessment.
Detailed heritage assessments are now underway for priority properties, including historical research, site inspections and ongoing consultation with property owners. This work will continue over the coming months, with findings expected to be available in early 2026.
Further information about the Modern Architecture Study is available on the Northern Beaches Council website.
