A custom home in Greenwich costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Lane Cove Council approvals and fixed-price construction.
Building Custom Homes in Greenwich
Custom home in Greenwich is harbour-fall heritage on the Sydney Harbour peninsula — Federation mansions and inter-war heritage on 500–1,200m² blocks with substantial fall to Greenwich Point and Manns Point. Heritage Conservation Areas cover most streets. Sandstone-dominant; rock excavation $25K–$60K typical. Realistic premium $4,500–$6,800/m² for 320–480m² build. Pre-construction 7–9 months including heritage, tree and foreshore consents.
Most Greenwich blocks run 500–1,200m² on Class M (sandstone ridges) / H–E (river fall) ground. Custom home design works best when the floor plan is drawn to your specific block — orientation, slope, views, neighbours' overlooking — rather than dropping a catalogue plan onto land it was never designed for. Median price band: $3.5M–$8.0M. Nearest rail is Wollstonecraft (1.5 km, ferry).
Buildana's design-and-construct service covers everything — from initial design brief and land assessment through to council approval and fixed-price construction. One builder, one contract, one point of contact.

Why Build a Custom Home in Greenwich?
Greenwich is the harbour-fall peninsula between Greenwich Point, Manns Point and Bay Road on Sydney Harbour. Federation mansions, inter-war heritage and contemporary harbour-fall builds on 500–1,200m² blocks. Heritage Conservation Areas cover most streets. Sandstone-dominant with substantial harbour fall. North Sydney LGA boundary east at Wollstonecraft. Greenwich ferry wharf. Premium for direct harbour outlook.
Greenwich's established streetscape and median house prices of $3.5M–$8.0M 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 (1.5 km, ferry) connects Greenwich to the wider Sydney network. Custom home construction here benefits from 500–1,200m² blocks that allow generous floor plans — single or double storey designs with proper setbacks and outdoor living. Class M (sandstone ridges) / H–E (river fall) soil (extremely reactive) is standard for Greenwich — Buildana includes engineered slab design in every quote.
Custom homes in Lane Cove range across the LGA's split character — Federation mansion replacements behind retained heritage facades on the harbour-fall peninsulas (Greenwich, Longueville, Northwood, Linley Point) at premium spec; mid-tier custom on inland Lane Cove village and Lane Cove North; bushfire-rated builds on Lane Cove National Park-adjacent lots in Lane Cove West and Riverview. Realistic premium custom $4,000–$6,500/m² for 280–450m² high-spec build, peaking on harbour-fall blocks where engineering, sandstone excavation and access constraints stack costs. Pre-construction 5–8 months including heritage and tree consents on protected streets.
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 Greenwich — Local Context
Foundations & Slab Design for Greenwich
Greenwich's ground is extremely reactive clay (Class M (sandstone ridges) / H–E (river fall)). On a 500–1,200m² block, that translates to engineered slab work in the $45,000–$80,000 bracket for a custom home. Double-check any quote that doesn't itemise the slab — 'slab as per engineering' usually means the builder will hit you with a variation once the soil report comes back. We commission the geotech upfront, before pricing, so the cost in your contract reflects what your block actually needs. If your neighbour's home shows movement cracks above architraves or below window sills, that's a signal worth knowing before you finalise design — Buildana's site assessment looks at adjacent stock too.
Approval Timeline for Greenwich
Realistic timeline for a custom home in Greenwich: 10–15 business days CDC, or 8–14 weeks DA — depends on the design. Add 2–4 weeks before lodgement for documentation, BASIX certificate, geotech report, and survey if you don't already have one. Construction Certificate is issued separately before works commence.
Cost vs Value in Greenwich
Median sale price in Greenwich is $3.5M–$8.0M. For a custom home, the decision tree runs through three numbers: build cost, expected post-completion value, and how long you plan to hold. New custom homes in Greenwich re-set the property at the top of the local price band, with new-build premium of 10–20% over comparable established stock. We map this in feasibility before you commit.
Greenwich Housing Stock & What That Means
Most homes in Greenwich were built 1880s–1940s heritage. That puts asbestos risk firmly in play — sheeting, eaves linings, vinyl floor tiles, and pipe lagging are likely. Licensed removal adds $5,000–$25,000 to a custom home where demolition is involved, and Buildana manages SafeWork NSW notifications, removal, and clearance certificates as part of the contract.
Building Activity in Greenwich Right Now
Greenwich is seeing steady residential activity — vacant lot turnover and KDR activity is generating consistent custom home demand across the suburb. Buildana sits inside that pipeline — we know what's getting approved, what's stalling, and why.
Builder's Take on Greenwich
Most disputes I see with custom home clients trace back to one thing: vague contracts. In Greenwich specifically, where Lane Cove Council's DCP has specific FSR and landscaped area rules, the contract has to call out setbacks, heights and compliance as included — not "subject to council". Buildana contracts include Lane Cove Council approval as a fixed item. If we misjudge the envelope, that's our cost, not yours.
Honest take on Greenwich: the 1880s–1940s heritage housing stock is at the point where most owners are better off building new than spending $300K on a deep renovation. The blocks are wide enough, the zoning works, and Lane Cove Council's CDC pathway is predictable. The mistake I see people make is signing with a project builder and discovering after slab that "allowances" were placeholders — not real prices. Every Buildana contract itemises inclusions by brand and model up-front.

How It Works
From First Call to Final Key
We start at the kerb. Before a single sketch, we stand on your Greenwich block and work out what the land wants — sun path, slope, views, neighbours, the R2 Low Density / R3 Medium (Lane Cove village) envelope we've got to design inside. That walk determines almost every decision that follows.
⏱Design happens in layers. First the plan — where the kitchen is, how the bedrooms stack, what the morning routine looks like. Then the envelope — roof pitch, eave depth, window sizes matched to the Greenwich climate. Then the finishes. Nothing gets drawn without a reason you can point to.
⏱Documentation is the unglamorous part, but it's where most projects go wrong. Engineering for Class M (sandstone ridges) / H–E (river fall) soil, BASIX 2025, Lane Cove Council drawings, hydraulics, stormwater. We stage it so the certifier approves the first time — not the fourth.
⏱Then we build. Programme in hand, trades booked, material orders placed weeks before they're needed so nothing waits on delivery. Weekly update, monthly milestone walk, defects fixed as we go rather than collected at the end.
⏱Quality Promise
Every Buildana custom home in Greenwich is designed for your block and built under a fixed-price contract — no surprises, no hidden extras.
