A home extension in Carramar costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Fairfield City Council approvals, and construction under one fixed-price contract.
Carramar Home Extensions & Additions
A home extension in Carramar keeps the station and adds the space — post-war and 1960s homes on standard blocks extend across the rear for the growing household, with the rail connectivity holding the value.
The era read leads: the fibro gets the licensed strip-out where touched, and out beats up on the lighter framing.
At the $900K to $1.15M median, the staying maths lands clearly — and the granny-flat comparison is run where the household's shape suits it.
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 Carramar — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Extension or granny flat — compared
Carramar's blocks often suit both paths — the rear extension for the bigger single household, the granny flat where the family's shape wants separation — and I compare them honestly on your block before you commit.
The station keeps either result in demand.
Era handled properly
The post-war fibro gets licensed strip-out where the work touches it, and out beats up on the lighter framing.
The strip-out is a costed line before work starts.

How It Works
From First Call to Final Key
We assess your Carramar home — existing structure, block size (450–700m²), 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 Carramar home's streetscape. Multiple design options presented.
⏱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.
⏱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.
