A duplex in Vaucluse is not the play, full stop, and the numbers make that obvious. This is the harbourside mansion ridge from Rose Bay to South Head, grand Federation and contemporary homes on 500 to 2,500m2 blocks, in a $5M to $30M-plus market. Larger blocks clear the 600m2 Woollahra minimum with ease, but nobody splits mansion land into a duplex when a single trophy home returns multiples more.
Heritage Conservation Areas cover virtually all streets, so that is checked first. The ground is sandstone-dominant with rock anchoring standard on the harbour fall, so the real project here is a single premium build or a heritage restoration, engineered to suit the slope and the rock.
What I would check first on your Vaucluse block: the heritage status and the outlook, but honestly, the answer here is a single home, not a duplex.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you honestly what suits it.

Mansion land, not duplex land
Vaucluse blocks run 500 to 2,500m2 and clear the 600m2 Woollahra minimum with ease.
But at a $5M to $30M-plus market, a single trophy home returns far more than splitting the land into two.
Heritage and rock
Heritage Conservation Areas cover virtually all streets, checked first.
Sandstone with rock anchoring standard on the harbour fall means a single premium build engineered to suit.
