Ermington Home Builds — Made to Your Brief
A custom home in Ermington is a riverside build where the ground history matters as much as the design. This Parramatta River suburb runs post-war brick and contemporary on 450 to 700m2 blocks, with R4 master-planned redevelopment on the former Defence land, and at a $1.4M to $2.0M market a designed replacement is a sound play near the Parramatta Light Rail corridor. The river setting is the draw, and the ground needs a proper look.
The ground is Wianamatta Shale on the higher streets, with Class P and E alluvial soils near the river, so footings are engineered off geotech to suit the specific lot. On remediated parcels near the former industrial land a contamination check is worth confirming before you build. On a standard block a considered family home works cleanly, and where older homes carry fibro a licensed asbestos strip-out comes first.
What I would check first on your Ermington block: the shale-versus-alluvial footing design near the river, any contamination history on remediated parcels, and the building envelope. Those set the home.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you where it stands.
Buildana's design-and-construct service covers everything — from initial design brief and land assessment through to council approval and fixed-price construction. One builder, one contract, one point of contact.

Check the ground

How It Works
From First Call to Final Key
We come to your Ermington site or you visit our office on The Horsley Drive in Fairfield. Either way, you leave the meeting with a clear cost band, an outline timeline, and a yes/no on whether your block supports the home you have in mind. The hard yards happen here, not at design lock-in.
⏱Our designer draws up plans matched to your Ermington block — north-facing living, compliant setbacks, garage placement, and outdoor flow. You get floor plans, elevations, and 3D renders to review before we lock in the design.
⏱Documentation is where bad builders cut corners and good builds stay on track. Buildana commissions the borehole, instructs the engineer, prepares BASIX, and aligns hydraulic, structural, and architectural drawings before lodgement. Certifiers reject sloppy packages — ours go in clean.
⏱CDC fast-track (10–15 business days) or DA through City of Parramatta Council (40–90 days). Ermington is zoned R2 Low. Construction Certificate obtained before works commence.
⏱Slab, frame, lock-up, fit-out, external works — all under fixed-price contract. Dedicated project manager on your build, weekly progress reports, and quality inspections at every critical hold point.
⏱OC, six-year structural warranty, two-year non-structural warranty, all manufacturer warranties on appliances and fixtures, BASIX certificate, certifier sign-offs, and maintenance schedule — all handed over in a single documentation pack. Keep it for your records and any future sale.
