A knockdown rebuild in Ermington is a solid riverside play — post-war brick on 450 to 700m² blocks on the Parramatta River, with the light rail corridor close and the former Defence-site redevelopment lifting the suburb. The aging post-war stock suits a straightforward rebuild.
Two site factors to check: the Class P/E alluvial ground near the river needs a footing designed for it off a real geotech, and the remediated former-industrial parcels carry contamination management worth a due-diligence look on nearby blocks.
The post-war stock can carry asbestos, so a licensed strip-out leads the demolition. Against the 600m² duplex minimum, the larger blocks qualify for a dual-occupancy.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility, with the ground and checks handled, before you commit.
Buildana manages the complete knockdown rebuild process in Ermington — 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 riverside suburb on the up
Ermington's position on the Parramatta River, the light rail corridor and the former Defence-site redevelopment are lifting the suburb, and the aging post-war stock on 450 to 700m² blocks suits a straightforward rebuild.
Against the 600m² duplex minimum, the larger blocks qualify for a dual-occupancy, which I cost where relevant.
Alluvial ground and remediation checks
Near the river, the Class P/E alluvial ground needs a footing designed for it off a real geotech. On blocks near the remediated former-industrial parcels, the contamination management is worth a due-diligence look, raised upfront.
The post-war stock can carry asbestos, so a licensed strip-out leads the demolition.

How It Works
From First Call to Final Key
KDR starts with an honest look at the existing house. Sometimes it's worth keeping. Most Ermington homes from the 1950s–1970s + 2010s+ apartments — especially fibro and brick-veneer — are beyond the point where renovation makes sense. We tell you straight.
⏱Demolition is pre-approved to run parallel with rebuild design. Asbestos cleared, services abolished, site stripped in a single mobilisation. Geotech reconfirms Class M soil with the old house gone.
⏱New house goes up on the same footprint or a better one, whichever serves the block. Modern NCC envelope, better orientation, fit-for-purpose room sizes. The suburb stays the same; the house finally fits it.
⏱Final handover: new OC, six-year structural warranty, all the documentation on your Ermington block you'd get on a greenfield build. The only difference is you still live in the street you chose.
