Extending Homes in Concord West
A home extension in Concord West starts with a zoning check. Along Concord Road and near the station, the R3/R4 corridors carry development value the wing has to be weighed against; away from them, the quiet cottage streets extend confidently behind conserved frontages. So the first move is confirming which Concord West your block sits in.
On the cottage streets the era read decides the approach, the pre-war fabric gets licensed handling for lead paint and asbestos, and the footings are assessed where the new wing ties into the old. The rail keeps demand for the finished home dependable.
At a $2.0M to $3.8M median, a wing on the quiet streets is the natural play — you keep the rail-side convenience and add the family space the cottage never had.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with the zoning checked, before you commit.
Buildana manages the complete home extension process in Concord West — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Corridor or cottage street
Along Concord Road and near the station the zoning value is checked before any wing — while the quiet cottage streets extend confidently: conserved frontages, family wings behind, the rail holding demand.
The spend follows an honest read of where your block sits.
Fabric handled properly
The pre-war fabric carries lead paint with the asbestos, both handled under licence.
The footings are assessed where the wing ties in, and every part of it is costed upfront.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. On-site assessment of your 1900s–1960s + apartments-era home in Concord West. We check structural condition, block dimensions (450–800m²), setback availability, and City of Canada Bay Council's DCP requirements. Written feasibility and cost estimate provided. Designing an extension is half about the new space and half about how it joins the old one. Doorway position, ceiling height transition, floor level matching, light wells — the junction makes or breaks how the finished home feels.
⏱The Concord West construction phase. Fixed price, programmed, supervised. We lodge your extension approval — CDC for eligible designs or DA through City of Canada Bay Council. Full documentation including structural engineering for Class M–H soil, BASIX, and shadow diagrams. CC issued before works start. For ground-floor rear extensions you usually stay in the house during the build, with temporary weatherproofing at the junction wall until the new section is locked up. Second-storey additions need a 4–8 week relocation during the roof-off and frame-up phase.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspection, Occupation Certificate, 6-year structural warranty. Your Concord West home now has the space your family needs.
