A home extension in Revesby 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.
Revesby Home Extensions & Additions
A home extension in Revesby has a lot going for it, and most of it comes down to the blocks. The 1940s to 1970s homes here tend to sit on 500 to 700m² with proper depth out the back, so there is genuine room for a full family wing without squeezing the yard to nothing. Add the station a short way off and you have a suburb where growing the house makes more sense than chasing space somewhere with a worse commute.
Whether the wing goes ahead depends on the original home. Good brick carries it easily. A fibro place that has had its day gets a rebuild comparison instead of a wing bolted onto a shell that cannot hold it. Fibro that turns up as we open the house is stripped out under licence before framing.
At a $1.1M to $1.4M median the case for staying is clear-cut when the house earns it. New footings are engineered to your ground so the addition and the original stay locked together.
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 Revesby — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Deep blocks earn full wings
The 500 to 700m² blocks are the reason Revesby extends so well — a second living space, extra bedrooms and a new kitchen line go across the back with the yard still intact.
The station and shops keep everyday life ticking through the build, and if the original is too tired to carry the wing, I put the rebuild numbers in front of you first.
Fibro and footings, no shocks
Any fibro uncovered as we open the house is stripped out under licence, clearance certificate in hand, before a single new stud goes up.
The footings are engineered to the ground beneath your slab, and both jobs 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. Revesby 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.
