A custom home in Bilgola Plateau is an elevated bushland build with an ocean-view payoff on the eastern fall. The suburb above Bilgola Beach runs 1960s to 1990s brick and mid-century pole houses on 600 to 1,200m2 blocks, and at a $2.6M to $5M market a designed replacement oriented to the view is a strong play. The elevation and the outlook are what owners build here for.
Most lots backing Hudson Park Reserve carry a BAL rating from 19 up to Flame Zone, so an RFS assessment is standard and the spec answers the risk. This is Hawkesbury Sandstone with deep rock excavation running $60K to $150K on many sites, so the substructure is engineered and priced honestly up front. On the eastern fall a level-changing design captures the ocean view, and a pole or stepped approach suits the steeper blocks.
What I would check first on your Bilgola Plateau block: the BAL rating, the rock and substructure cost, and how the home captures the eastern view. Those set the home.
We build these fixed-price, licence HBL 487805C. Show us your fall and outlook and we will design to it.
