Home Extension Builder in Glenfield
A home extension in Glenfield builds beside the hub — the station's connectivity keeps demand steady, and the 1970s-90s stock on standard blocks takes the rear family wing that lets the household stay.
The era read leads: brick extends cleanly, older fibro gets the licensed strip-out, and the Class H junctions are engineered.
At the $900K to $1.1M median, the staying maths beats upsizing clearly.
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 Glenfield — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

The hub keeps it practical
Glenfield's station connects everywhere — and the extension keeps it: the rear wing adds the bedrooms and living while the commute stays effortless.
The 1970s-90s stock takes the addition on the era read.
Era and clay handled
Older fibro gets the licensed strip-out where touched, and the Class H junctions are engineered.
Both are priced up front, not variations later.

How It Works
From First Call to Final Key
The first job on an extension is finding out what you're extending onto. Glenfield homes from the 1970s–1990s 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.
