A home extension in Lurnea runs the era check first — the post-war stock splits between brick worth the wing and fibro where the rebuild comparison wins, and the answer comes before the spend.
Where the extension proceeds: rear wing with the family's bedrooms and second living, post-war asbestos handled by licensed strip-out, Class H junctions engineered.
At the $800K to $1.0M median, the value equation strongly favours adding rooms where the house deserves them.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.

The check before the spend
Lurnea's post-war stock is old enough that extending a tired house can be money misplaced — so the brick-versus-fibro check comes first, honestly, before the wing is designed.
Where the house deserves it, the value equation is strongly in the extension's favour.
Asbestos and clay handled
The post-war asbestos gets licensed strip-out with clearance certificates, and the Class H junctions are engineered.
The strip-out and the junctions are both costed up front.

How It Works
From First Call to Final Key
We assess your Lurnea home — existing structure, block size (500–650m²), R2 Low Density zoning, setbacks, FSR, and your space requirements. You'll know what's achievable before spending on detailed design.
⏱Design phase covers the extension layout, junction with existing structure, window and door placement, and external finish to match your Lurnea home's streetscape. Multiple design options presented.
⏱Documentation pack covers structural engineering for the new footings sized to match existing depths on Class H soil, BASIX 2025 compliance, shadow diagrams to neighbours' POS, hydraulic, and detailed sections through the wall-tie junction. Approval-grade, not concept-grade.
⏱Fixed-price construction of your extension. New footings engineered for Class H soil, structural connection to existing home, frame, fit-out, and finishes.
⏱Handover documentation covers the new work specifically — OC for the extension, structural certs, BASIX certificate updates, and warranty for the new section plus the junction detailing. Existing house remains under whatever warranty position applied before.
