A home renovation in Bilgola Plateau often means working with a mid-century pole house or a home stepping down the bushland fall, which takes real understanding of the existing structure. The stock sits on 600 to 1,200m² elevated blocks, and a sensitive renovation that captures the ocean outlook on the eastern fall usually beats a generic gut-and-replace. Most lots carry a BAL rating from 19 to Flame Zone, so the bushfire spec shapes any external work.
The Hawkesbury Sandstone brings deep rock excavation, typically $60K to $150K, on any structural work. Where the older home has fibro, a licensed asbestos strip-out fronts the demolition of the affected sections. The slope and the existing footings need proper assessment before a heavy addition.
What I check first on your Bilgola Plateau renovation: the existing structure on the slope, the BAL rating, and the depth to rock. Those three shape the cost and the scope.

Work with the slope and the structure
Bilgola Plateau's mid-century pole houses and slope homes are doing clever structural things already, so a renovation has to understand the existing frame rather than fight it. A sensitive renovation opens the home to the ocean outlook on the eastern fall, modernises the services and weatherproofing, and works with the bushland setting. Gutting one of these to a generic plan usually loses what made it worth buying.
On the slope, any heavy addition depends on the existing footings and the ground, so those get assessed properly before design. That is exactly what our scope reads first.
Bushfire and rock
Most Bilgola Plateau lots carry a BAL rating from 19 to Flame Zone against Hudson Park Reserve, so any new or altered external fabric meets the bushfire spec with toughened glazing, ember screening and non-combustible cladding scaled to the rating. The Hawkesbury Sandstone brings deep rock excavation, typically $60K to $150K, on structural work. I cost both from real assessments, never a guess.
