A home extension in Linley Point costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Lane Cove Council approvals, and construction under one fixed-price contract.
Second-Storey & Rear Additions in Linley Point
A home extension in Linley Point works one of the area's most tightly-held enclaves — a quiet peninsula on the Lane Cove River that people simply do not leave. The heritage homes on 700 to 1,500m² blocks fall to the water, so the wing is built to open the living toward the river while the conserved frontage stays exactly as the street knows it.
Because these lots sit on sandstone, significant rock applies where the structure changes, and it is priced from the geotech up front rather than guessed. The fall is engineered early, and the pre-war fabric has lead paint and asbestos handled as licensed work.
At a $3.5M to $7.0M median, a wing that earns the river is a sound long-term move — the scarcity of stock on the peninsula underwrites every metre you add.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with rock and fall priced, before you commit.
Buildana manages the complete home extension process in Linley Point — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

A peninsula people hold onto
Linley Point is tightly held for the river and the heritage, and the wing serves both — conserved fabric kept, living opened to the water down the fall, on blocks with genuine room.
The scarcity of what changes hands here underwrites every metre you add.
Rock, fall and fabric
Significant rock applies where the structure changes, so it is priced from the geotech, and the fall is engineered early.
The pre-war hazards run as licensed processes, all in the scope before you commit.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your Linley Point home — existing structure, block size (700–1,500m²), 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 Linley Point home's streetscape. Multiple design options presented.
⏱The Linley Point construction phase. Fixed price, programmed, supervised. Documentation pack covers structural engineering for the new footings sized to match existing depths on Class M 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 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.
