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
Extension is the dominant scope in Linley Point given heavy heritage controls. Federation mansion additions on harbour-fall sites with suspended slab engineering and structural underpinning. Realistic budget $500K–$1.5M for premium 80–140m² addition. Pre-construction 7–9 months.
On the ground in Linley Point (2066), the practical numbers shape every home extension. Class M (sandstone ridges) / H–E (river fall) soil — extremely reactive clay — pushes engineered foundation work into the $45,000–$80,000 bracket on most 700–1,500m² blocks. R2 Low Density / R3 Medium (Lane Cove village) zoning under Lane Cove Council sets the building envelope, with R3 Medium Density pockets that open up dual occupancy options on qualifying lots. Median sale price across Linley Point sits at $3.5M–$7.0M, which frames the build-versus-buy decision from the start. Nearest rail is Wollstonecraft (5 km, ferry from Greenwich), and that proximity affects everything from rental demand to construction site access.
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.

Why Extend Your Home in Linley Point?
Linley Point is the river-fall peninsula extending into the Lane Cove and Parramatta Rivers. Federation mansions, inter-war heritage and contemporary river-fall builds on 700–1,500m² blocks with substantial fall. Heritage Conservation Areas cover most streets. Sandstone-dominant with significant rock excavation. Hunters Hill LGA boundary at Tarban Creek. Premium harbourside outlook.
Linley Point's established streetscape and median house prices of $3.5M–$7.0M reflect a premium location within Lane Cove. Building costs sit above the metro average, offset by stronger capital growth and rental returns. Transport access via Wollstonecraft (5 km, ferry from Greenwich) connects Linley Point to the wider Sydney network. 1900s–1950s heritage-era homes in Linley Point often have good structural foundations worth building on. Extensions add living space at a fraction of the full rebuild cost. Class M (sandstone ridges) / H–E (river fall) soil (extremely reactive) is standard for Linley Point — Buildana includes engineered slab design in every quote.
Extensions are the dominant scope across the heritage harbour-fall peninsulas (Greenwich, Longueville, Northwood, Linley Point) where KDR is restricted. Federation mansion additions, sandstone terrace reconfiguration, river-fall heritage-grade work all common. Suspended slab engineering on river-fall sites; bushfire BAL upgrades on Lane Cove West and Riverview bush-edge lots. Heritage Council expects retention of stained glass, ornate plasterwork, marble fireplaces, slate roofing on protected streets. Realistic budget $400K–$1.4M for thoughtful 60–130m² addition; $700K–$2M for premium harbour-fall heritage-grade work.
Planning Controls — Lane Cove Council
Lane Cove LEP 2009 & Lane Cove DCP 2010. R2 Low Density dominates the LGA: FSR 0.5:1, building height 9.5m, front setback 7.5–9m varying by streetscape, landscaped area 35–40%. R3 Medium Density along Burns Bay Road, Longueville Road and the Lane Cove village core permits FSR up to 0.8:1. R4 High Density and B4 Mixed Use along the St Leonards / Crows Nest fringe in Lane Cove North. The 2024 Crows Nest Metro SEPP TOD precinct overlay reaches the south-eastern portion of Lane Cove North, opening density bonuses inside 400m of Crows Nest Metro station. Heritage Conservation Areas cover most older streets in Greenwich, Longueville, Northwood, Linley Point, Lane Cove West, Riverview and parts of Lane Cove village. Tree Preservation Order applies LGA-wide. River-fall and harbour-fall sites on the Lane Cove River and Sydney Harbour peninsulas (Greenwich, Longueville, Northwood, Linley Point) require engineered slab and retaining design — sandstone rock excavation $20K–$60K standard. Lane Cove National Park frontage on Lane Cove West and Riverview adds bushfire BAL ratings on bush-edge lots.

Building in Linley Point — Local Context
Ground Conditions That Affect Your Build
Class M (sandstone ridges) / H–E (river fall) is the rule across Linley Point — extremely reactive clay. For your home extension, expect engineered footings in the $45,000–$80,000 range. The variables that shift you up or down inside that band: building footprint, number of storeys, point loads (heavy stone benchtops, masonry feature walls), and whether the adjacent stormwater system needs upgrading. Linley Point is close to Wollstonecraft (5 km, ferry from Greenwich) station — site access on tighter blocks adds a logistics premium, which is why we cost cranage and material delivery before signing, not after.
Lane Cove Council & Approval Pathway
Linley Point sits inside the Lane Cove LGA, governed by Lane Cove Council. For a home extension, the approval question is usually CDC vs DA. Extensions in Linley Point usually need a full DA through Lane Cove Council — typically 40–90+ days from lodgement, longer if neighbour notification triggers objections. Either way, we manage submission, RFIs, and re-lodgement in-house — you don't deal with the council.
What a Extension Costs in Linley Point
Linley Point's median house price sits at $3.5M–$7.0M. That's the number that decides whether a home extension stacks up financially. If you're spending more than 50% of $3.5M–$7.0M on a extension, the economics tilt toward knockdown rebuild instead. Worth running the numbers properly before locking in scope. Buildana provides itemised quotes — no provisional sums, no allowances, no "as per engineering" line items.
Designing for the Linley Point Streetscape
Linley Point's housing stock is predominantly from the 1900s–1950s heritage. Wollstonecraft (5 km, ferry from Greenwich) from the nearest station. The local anchor is Linley Point Reserve & Tarban Creek. For a home extension, the streetscape question matters more than most builders admit — a brand-new double-storey on a street of single-storey 1900s–1950s heritage weatherboards will draw council attention on bulk and scale, even if technically compliant. Buildana designs the front elevation to read appropriately for the street while modernising the floor plan and structure behind it. Materials palette, roof pitch, fenestration rhythm — all chosen to settle into the existing rhythm rather than fight it.
Why Some Linley Point Builds Stall
Builds in Linley Point stall for predictable reasons. Lodgement defects (missing BASIX, wrong drawing scale, undeclared overlays). Soil surprises on Class M (sandstone ridges) / H–E (river fall) ground when the builder didn't commission a borehole upfront. Variation creep when the contract was light on inclusions. Trade scheduling gaps when the builder is over-committed across too many sites. Lane Cove Council delays when neighbour objection triggers committee review. Buildana protects against each of these at contract stage — fully documented lodgement pack, geotech in the price, itemised inclusions instead of allowances, and a tight project-manager-to-job ratio that keeps trades moving.
Builder's Take on Linley Point
BASIX re-certification on extensions catches people out. Any extension over 50m² triggers BASIX on the combined envelope. Your existing home might be well short of 7-star, so the extension has to pull the whole house closer to compliance. That can mean insulation upgrades in the existing walls and ceiling.
The cost-per-square-metre on an extension is almost always higher than new build — roughly $3,800–$5,500/m² vs $3,200–$4,500/m² for new. Reason: connecting new to old adds engineering, matching adds material cost, working around occupation adds time. Budget accordingly.

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 / R3 Medium (Lane Cove village) 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 (sandstone ridges) / H–E (river fall) 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 (sandstone ridges) / H–E (river fall) 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.
