Knockdown Rebuild Longueville — One Contract, Demo to Keys
Everything under one agreement in Longueville 2066: demolition, asbestos removal, site prep, design, approvals, engineering, new home construction, landscaping and Occupation Certificate.
Longueville KDR — Single Contract, New Home
A knockdown rebuild in Longueville is a premium harbour-fall project on the peninsula on the north side of Tambourine Bay and Woodford Bay — Federation mansions, inter-war heritage and contemporary harbour-fall builds on 600 to 1,400m² blocks. A rebuild lets you design a substantial home around a genuine harbour outlook.
The sandstone-dominant ground brings rock on the substructure, and the substantial fall to the water 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.
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 Longueville — 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
Longueville is the harbour-fall peninsula on the north side of Tambourine Bay and Woodford Bay, with Federation mansions and contemporary harbour-fall builds on 600 to 1,400m² blocks and Lane Cove River frontage. A rebuild designs a substantial home around a genuine harbour outlook.
It is a sought-after harbourside pocket where a quality rebuild holds real value.
Rock, fall and heritage
The sandstone-dominant ground brings rock on the substructure, and the substantial fall to the water 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.
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.

How It Works
From First Call to Final Key
Site visit covers everything that affects the build cost: vehicle access for trucks and crane, services (sewer depth, water connection, electrical service rating), soil exposure for borehole, neighbouring construction, and any obvious heritage or tree constraints. Real numbers, not estimates.
⏱Architectural design for your replacement home, structural engineering for Class M soil, BASIX certification, and all approval documentation. Lodged as CDC (10–15 days) or DA (40–90 days) depending on design.
⏱Demolition runs 5–10 working days for a standard Longueville cottage — longer if asbestos volume is significant or the structure includes a brick chimney or solid-block walls. Asbestos work happens first under a controlled removal program before mechanical demo starts.
⏱New home built from engineered slab (Class M soil) to keys — fixed-price, milestone-based progress payments. Your project manager provides weekly updates.
⏱Walk through your finished home on your original Longueville block. OC issued, all services live, 6-year structural warranty, appliance manuals, and maintenance schedule. Move in.
