A home extension in Smithfield works well-sized residential blocks minutes from the industrial belt's jobs — 450 to 700m² under 1960s-80s stock that takes the rear family wing.
The era read leads: brick extends cleanly, fibro gets the licensed strip-out, and the reactive pockets get footings engineered to the ground.
At the $900K to $1.15M median, extending keeps the short commute and the established streets.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.

The short-commute keeper
Smithfield families often work minutes away — and extending keeps that: the rear wing adds the bedrooms and living while the commute stays short and the streets stay familiar.
The well-sized blocks take the addition without crowding the yard.
Era and ground handled
Brick extends cleanly, fibro gets the licensed strip-out where the work touches it, and the reactive pockets get engineered footings.
All of it is costed into the scope up front.

How It Works
From First Call to Final Key
On-site assessment of your 1960s–1980s-era home in Smithfield. We check structural condition, block dimensions (450–700m²), setback availability, and Fairfield City Council's DCP requirements.
⏱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.
⏱We lodge your extension approval — CDC for eligible designs or DA through Fairfield City Council. Full documentation including structural engineering for Class M–H soil, BASIX, and shadow diagrams.
⏱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.
⏱Final inspection, Occupation Certificate, 6-year structural warranty. Your Smithfield home now has the space your family needs.
