A knockdown rebuild in Greenwich costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Lane Cove Council approvals, and construction under one fixed-price contract.
New Home on Your Greenwich Block
A knockdown rebuild in Greenwich is a premium harbour-fall project on the peninsula between Greenwich Point, Manns Point and Bay Road — Federation mansions, inter-war heritage and contemporary harbour-fall builds on 500 to 1,200m² blocks with substantial harbour fall. A rebuild lets you design a substantial home around a direct harbour outlook.
The sandstone-dominant ground brings rock on the substructure, and the substantial fall means suspended slabs and substantial retaining on the fall lots. I get a real geotech so the rock, fall and retaining are all costed properly. There is a ferry wharf here, with Wollstonecraft station around 1.5km.
Heritage Conservation Areas cover most streets, so a rebuild generally goes down the DA path, and on a heritage mansion a restoration is worth weighing. The pre-war stock can carry asbestos and lead paint, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility, with the rock and fall costed, before you commit.
Buildana manages the complete knockdown rebuild process in Greenwich — from site assessment and architectural design through to DA or CDC approval, demolition management, and fixed-price construction to handover. One builder, one contract, one new home.

A premium harbour peninsula
Greenwich is the harbour-fall peninsula between Greenwich Point, Manns Point and Bay Road on Sydney Harbour, with Federation mansions and contemporary harbour-fall builds on 500 to 1,200m² blocks. A rebuild designs a substantial home around a direct harbour outlook, with a ferry wharf on the doorstep.
It is a sought-after harbourside pocket where a quality rebuild holds real value.
