A home extension in Mount Lewis catches a small pocket on the up. It is a compact residential area right by the Bankstown CBD, post-war homes that are steadily being done up, so a well-built wing on solid bones adds the space now and rides the neighbourhood's improvement for value later. Being that close to the CBD keeps demand real underneath it all.
The bones decide the job. Brick that has held up carries the wing; genuinely tired fibro gets a rebuild comparison instead of good money after bad. Any fibro opened up in the work is stripped out under licence before framing, and the footings are engineered to your ground.
At a $1.0M to $1.3M median the CBD proximity is what holds the result, whichever way the read on your particular house 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 Mount Lewis — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

A small pocket with momentum
Mount Lewis is doing up street by street, so a wing on sound bones gains twice — the room lands now, the pocket's lift comes later — with Bankstown CBD keeping demand steady.
If the original is too far gone to carry the work, I put the honest rebuild numbers in front of you first.
Fibro and footings, done properly
Fibro exposed once demolition starts is removed under a licensed strip-out ahead of any new framing.
Footings are engineered to your ground, and both jobs stay 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. Mount Lewis homes from the 1940s–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.
