A knockdown rebuild in Old Toongabbie is a practical family play — 1960s to 1980s brick on 500 to 750m² R2 lots between Toongabbie and Winston Hills, with a strong KDR and duplex market on the larger blocks. The aging stock suits a straightforward rebuild.
Against the 600m² duplex minimum, the larger blocks qualify, so I run the duplex numbers alongside the single rebuild where relevant.
The ground is Wianamatta Shale, so the slab is designed off a real geotech. The older homes can carry asbestos, so a licensed strip-out leads the demolition where needed.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility — rebuild or duplex — before you commit.
Buildana manages the complete knockdown rebuild process in Old Toongabbie — 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.

Practical, quiet, established
Old Toongabbie's 500 to 750m² lots and aging 1960s-80s brick stock make it a practical rebuild suburb between Toongabbie and Winston Hills, with bus connections to Parramatta. A knockdown resets a dated home into a modern one in a quiet, established pocket.
The KDR and duplex market on the larger blocks is already active.
Shale and era-dependent demolition
The Wianamatta Shale takes a slab designed off a real geotech. The demolition depends on the era: the older homes can carry asbestos and need a licensed strip-out.
Against the 600m² duplex minimum, the larger blocks qualify, so I run those numbers where relevant.
