A home extension in Schofields costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Blacktown City Council approvals, and construction under one fixed-price contract.
Second-Storey & Rear Additions in Schofields
A home extension in Schofields starts with working out which Schofields you are in. The older established homes extend on the classic logic — sound bones, a rear wing, more room for a growing family. The newer release stock on the growth-corridor side is mostly too young to need any of that, and gets a straight answer instead of a scope.
On the established blocks the era read leads the design, and any older fabric gets licensed handling where the work opens it up. Where the ground turns reactive, the footings tie old to new so the whole slab moves as one. The station and corridor amenity hold whichever result applies to you.
At an $850K to $1.1M median the staying maths works where the home genuinely deserves the wing — and I would rather tell you it does not than build something the house was never asking for.
We build these fixed-price, licence HBL 487805C. Tell me what you are working with and I will give you the honest read.

Two Schofields, two answers
The established homes extend on classic logic — a rear wing with the era read leading — while the release stock rarely needs it yet, and I say so rather than scope it.
The station and growth-corridor amenity hold either result in good stead.
Fabric and junction handled
Older fabric gets licensed handling wherever the work opens it up.
On reactive pockets the footing junction is engineered to move with the house, and both are inside 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. Schofields homes from the Mixed (established + new release) 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
Buildana's Schofields home extension process: assess the existing structure, design the addition, approve, build. Fixed price throughout.
