Elizabeth Hills Home Extensions — Fixed Price
A home extension in Elizabeth Hills grows the modern estate home — the 2000s-2010s stock is sound, and the earliest homes are hitting the point where growing families outgrow the plans.
On the 400 to 550m² blocks the addition is designed tight, the clean fabric keeps the work simple, and the Class H junctions are engineered. I say honestly where the home does not need it yet.
At the $900K to $1.1M median, the precise wing beats upsizing where the plan is genuinely outgrown.
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 Elizabeth Hills — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Growing families, precise answers
Elizabeth Hills' earliest 2000s homes now hold bigger households than planned — and the tight-designed rear addition solves it, with the family amenities keeping the estate worth growing into.
The newer stock rarely needs it yet, and I say so.
Clean and engineered
The clean fabric sends the budget into the new space, and the Class H junctions are engineered.
Both are line items in the quote up front.

How It Works
From First Call to Final Key
On-site assessment of your 2000s–2010s-era home in Elizabeth Hills. We check structural condition, block dimensions (400–550m²), setback availability, and Liverpool City Council's DCP requirements. Written feasibility and cost estimate provided.
⏱Designing an extension is half about the new space and half about how it joins the old one. Doorway position, ceiling height transition, floor level matching, light wells — the junction makes or breaks how the finished home feels.
⏱We lodge your extension approval — CDC for eligible designs or DA through Liverpool City Council. Full documentation including structural engineering for Class H soil, BASIX, and shadow diagrams. CC issued before works start.
⏱For ground-floor rear extensions you usually stay in the house during the build, with temporary weatherproofing at the junction wall until the new section is locked up. Second-storey additions need a 4–8 week relocation during the roof-off and frame-up phase.
⏱Final inspection, Occupation Certificate, 6-year structural warranty. Your Elizabeth Hills home now has the space your family needs.
