Licensed Home Extension Builder Yagoona
NSW licensed extension specialist. Yagoona 2199 extensions on 1950s–1970s-era homes require structural sign-off, Class M footings, and matched connection — we engineer and document properly.
Quick Answer
A home extension in Yagoona costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Canterbury-Bankstown Council approvals, and construction under one fixed-price contract.
Yagoona Home Extensions — Fixed Price
A home extension in Yagoona catches a suburb mid-lift. The post-war stock near the station is being done up street by street, so a well-built wing on a solid home rides that improvement — you get the space now, and the neighbourhood coming up around you does the rest for value over time.
It still comes down to the bones. Brick that has held up takes the wing; tired fibro gets a rebuild comparison rather than good money thrown after bad. Fibro exposed during the work is stripped out under licence before any new build, and the footings are engineered to your ground.
At a $1.0M to $1.25M median the value case is strong on a house worth extending. The station keeps the fundamentals solid whichever way the read on the original lands.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.
Buildana manages the complete home extension process in Yagoona — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Building into a rising street
Yagoona's renewal is already running, so a wing on sound bones gains twice — the extra bedrooms and living space land now, and the street's improvement lifts what is around you.
The station keeps the fundamentals strong, and I read the original honestly before committing you to a wing over a rebuild.
Fibro and footings, done right
Fibro uncovered in the work comes out under a licensed strip-out with a clearance certificate before framing.
The footings are engineered to your ground, and both jobs sit inside the fixed price from the start.

How It Works
From First Call to Final Key
The first job on an extension is finding out what you're extending onto. Yagoona homes from the 1950s–1970s were built to different standards — we open walls, check footings, verify load paths. The existing house has to carry the new work.
⏱Design follows the existing roof. A bad extension looks like a bolt-on; a good one reads as original. Matched brickwork or contrasting render (whichever the architecture calls for), tied-in roofline, continuous flooring where it should be continuous.
⏱Construction happens while you live in the house. That means weatherproofing every night, staging the works so kitchens and bathrooms don't disappear on the same week, and keeping the site clean of debris that doesn't belong in a family home.
⏱Finish is seamless. Paint match, floor match, roofline match, brick match where possible. The only way to tell the extension is new is the date on the plans.
⏱Quality Promise
Yagoona home extension specialists: we work on your home while you live in it, weatherproof the site nightly, finish clean.
