Second-Storey & Rear Additions in Hinchinbrook
A home extension in Hinchinbrook grows the 1990s-2000s family home — sound stock the household has outgrown, which the rear wing solves without leaving the streets the kids grew up on.
The clean fabric keeps the work simple, and the Class H clay gets engineered footing junctions.
At the $850K to $1.05M median, extending beats upsizing clearly — the stamp duty alone funds a serious share of the wing.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.

The outgrown-home answer
Hinchinbrook's 1990s-2000s homes are sound but often too small for the household they now hold — the rear wing adds the bedrooms and second living without the upheaval of moving.
The clean fabric puts the whole budget into the new space.
The Class H junction
The Class H clay here means the footing tie is engineered so the wing tracks the house rather than pulling away.
The junction engineering is a line item in the quote.

How It Works
From First Call to Final Key
The first job on an extension is finding out what you're extending onto. Hinchinbrook homes from the 1990s–2000s 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
We extend Hinchinbrook homes with a structural engineer on every job. Second storey, rear addition, multi-room — engineered and priced upfront.
