Second-Storey & Rear Additions in Strathfield South
A home extension in Strathfield South grows the character home on the tighter blocks — Federation and inter-war stock on 300 to 600m² lots, extended behind conserved frontages where they apply.
The pre-war fabric gets licensed handling, party walls are assessed on the terraces, and the settled streets hold the result.
At the $2.4M to $3.5M median, the wing beats the friction of upsizing in the Inner West.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with the heritage position checked, before you commit.
Buildana manages the complete home extension process in Strathfield South — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Character on tighter blocks
Strathfield South's Federation and inter-war stock extends behind its conserved frontages — the family wing worked backwards on blocks that demand precision.
The Inner West position keeps demand deep.
Fabric and walls handled
Party walls are assessed on the terraces and semis, and lead paint joins asbestos on the pre-war fabric.
Both the party-wall work and the licensed strip-out are in the fixed price.

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–1940s Federation/Californian Bungalow + inter-war heritage + 2010s+ apartment redevelopment around Burwood CBD-era home in Strathfield South. We check structural condition, block dimensions (300–600m² (Federation/inter-war terraces and semi-detached predominant; Burwood CBD apartment-led)), setback availability, and Burwood 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 Strathfield South construction phase. Fixed price, programmed, supervised. We lodge your extension approval — CDC for eligible designs or DA through Burwood Council. Full documentation including structural engineering for Class M 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 Strathfield South home now has the space your family needs.
