A duplex in Linley Point is rarely the play, because near-total heritage coverage, significant rock and a premium river-fall market favour a single home. This river-fall peninsula extending into the Lane Cove and Parramatta Rivers runs Federation mansions and inter-war heritage on 700 to 1,500m2 blocks with substantial fall, and Heritage Conservation Areas cover most streets, so a dual-occupancy is constrained or precluded on contributory lots. At a $3.5M to $7.0M market a single premium home usually returns more than splitting a block.
The sandstone-dominant soil means significant rock excavation, so a duplex spreads a high site cost across two footprints. I would rather give you the honest read than push the wrong product. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Linley Point block: the heritage status, whether a single premium home is the clear best use, and the rock. That decides the direction.
We build these fixed-price, licence HBL 487805C. Send me the address and I will tell you honestly what the block suits.

Heritage and river fall
This river-fall peninsula runs Federation mansions and inter-war heritage on 700 to 1,500m2 blocks with substantial fall.
Conservation Areas cover most streets, so a dual-occupancy is constrained or precluded, at a $3.5M to $7.0M market.
Significant rock
The sandstone-dominant soil means significant rock excavation across both dwellings on a duplex.
A single premium home usually returns more than splitting a high-cost river-fall block, with older fibro stripped under licence.
