A home extension in Condell Park works because the blocks give you something to work with — 1960s and 1970s homes on 550 to 750m², with real depth out the back for a full family wing. The streets are established and steady, the kind of place where people would rather add a couple of rooms than uproot the whole household.
The brick from this era takes a ground-floor addition cleanly. Where the fabric of that period carries asbestos, it is stripped out under licence wherever the work opens it up. New footings are engineered to your ground so the wing does not pull against the original as the seasons move.
At a $1.0M to $1.3M median, staying and building beats the stamp duty of upsizing when the house is worth the spend. If the original is genuinely tired, I put the rebuild comparison on the table first.
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 Condell Park — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Room across the back
The 550 to 750m² blocks take a full rear wing — second living, bedrooms and a new kitchen line — while the established streets keep family life steady right through the build.
If what you own is too far gone to carry the work, I show you the honest rebuild numbers rather than talk up an addition.
Era and footings handled
Asbestos in the 1960s and 1970s fabric is removed under a licensed strip-out wherever we open the house.
The footings are engineered to your ground, and both that and the strip-out are locked into the fixed price from the outset.

How It Works
From First Call to Final Key
The first job on an extension is finding out what you're extending onto. Condell Park homes from the 1960s–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.
