A home extension in Lansvale checks the flood mapping first — the Georges River frontage means floor levels and habitable rooms on the lower blocks are shaped by the controls, and the design starts from them.
Beyond the mapping, the 1960s-80s stock on standard blocks takes the rear family wing, with the fibro era's asbestos handled by licensed strip-out and the reactive ground getting engineered footing junctions.
At the $900K to $1.15M median, extending keeps the river-side pocket the household chose.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with the flood mapping checked, before you commit.

The mapping shapes the wing
On Lansvale's lower blocks, the Georges River flood controls shape what the extension can be — floor levels, habitable rooms, sometimes the whole footprint — so I check the mapping before the design exists.
The higher blocks extend without the constraint, and the rear wing runs conventionally.
Era and ground handled
The fibro era's asbestos gets licensed strip-out where touched, and the reactive ground gets footing junctions engineered to move with the house.
The strip-out and the engineered junctions are both costed up front.

How It Works
From First Call to Final Key
The first job on an extension is finding out what you're extending onto. Lansvale homes from the 1960s–1980s 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.
