A home extension in Parklea is usually a case of a good house that ran out of room. The 1990s to 2000s stock sits on 550 to 700m² blocks near the Markets, sound and clean, and a rear wing adds the bedrooms, second living and alfresco the original plan never reached.
The clean fabric means your budget goes into the new space rather than into remediation. Where the ground turns reactive, the footing junction between the old house and the new wing is engineered to move as one, so the join holds up over the years rather than opening a crack.
At a $950K to $1.2M median the cost of trading up would build a good part of the addition by itself, and the block has genuine room for the design.
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 Parklea — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Good house, out of room
Parklea's 1990s to 2000s homes now hold bigger households than they were drawn for, and a rear wing solves it — bedrooms, a second living space and alfresco on a block with real depth.
Because the fabric is clean, the money goes straight into the new space.
Reactive ground, junction engineered
On reactive clay, the footing tie between old and new is engineered to move as a single slab.
That work is inside the fixed price from the outset, no late additions.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your Parklea home — existing structure, block size (550–700m²), 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 Parklea home's streetscape. Multiple design options presented.
⏱The Parklea construction phase. Fixed price, programmed, supervised. Documentation pack covers structural engineering for the new footings sized to match existing depths on Class M–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 M–H soil, structural connection to existing home, frame, fit-out, and finishes. Weekly updates from your project manager.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. 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.
