A custom home in Warrawee costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Ku-ring-gai Council approvals and fixed-price construction.
Custom Home Builder in Warrawee
Warrawee is small, premium, and almost entirely Heritage Conservation Area between Turramurra and Wahroonga. Most KDR proposals end up at full DA rather than CDC because of the heritage scrutiny. Lots 900–1,500m², Federation and inter-war back-street stock, and the Knox/Abbotsleigh school catchment underwriting the floor price. Custom designs here have to read as character-respecting from the street, even if the rear opens to a fully modern living wing.
Most Warrawee blocks run 900–1,500m² on Class M 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: $3.2M–$4.6M. Local services anchor around Warrawee station & Abbotsleigh proximity.
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 Warrawee?
Warrawee is the smallest premium pocket in the LGA — sits between Turramurra and Wahroonga on the T1 North Shore line. Blocks run 900–1,500m², heritage Federation and inter-war homes line the back streets, and the Knox/Abbotsleigh catchment lifts the floor price. Heritage Conservation Areas cover several streets, which means most KDR proposals here go through a full DA rather than CDC.
Warrawee's established streetscape and median house prices of $3.2M–$4.6M reflect a premium location within Ku-ring-gai. Building costs sit above the metro average, offset by stronger capital growth and rental returns. Warrawee station gives Warrawee direct rail access — a strong draw for residents and tenants. Custom home construction here benefits from 900–1,500m² blocks that allow generous floor plans — single or double storey designs with proper setbacks and outdoor living. Ground conditions (Class M) across Warrawee are well understood by local builders — Buildana's engineering accounts for moderately reactive soil movement.
Custom homes in Ku-ring-gai are the suburb's signature build type — large blocks, premium briefs, and a Council that takes streetscape seriously. The Heritage Character Assessment built into the LEP means even non-heritage-listed houses get scrutinised on form, materials and front setback. Realistic premium custom home cost runs $4,200–$5,800/m² for a high-standard 350–500m² two-storey build on a typical Pymble, Wahroonga or Killara block. Pre-construction is longer here than anywhere in Sydney — 4–6 months from brief to CC is normal because heritage and tree consents stack onto the standard DA. Engineered slab is mandatory on the Lane Cove valley side; sandstone footings on the ridge often need rock excavation costing $15K–$40K depending on depth. Buildana runs site investigation, geotech and contour survey at proposal stage so the contract sum holds.
Planning Controls — Ku-ring-gai Council
Ku-ring-gai LEP 2015 & Ku-ring-gai DCP. R2 Low Density: FSR 0.3:1 on lots under 1,200m² (sliding down to ~0.27:1 on larger lots), building height 9.5m, front setback 9–12m varying by streetscape, landscaped area 50%, deep soil 30%. Heritage Conservation Areas cover significant portions of Gordon, Killara, Pymble, Wahroonga, Warrawee, Roseville and Turramurra — heritage character assessment is required before any DA. Tree Preservation Order is one of Sydney's strictest: any tree over 5m high or 0.45m trunk circumference needs Council consent before removal. Bushfire planning (Planning for Bushfire Protection 2019) applies in St Ives, St Ives Chase, North Turramurra, North Wahroonga and bush-edge lots — BAL assessment is mandatory. The 2024 NSW TOD reforms permit medium density inside 400m of Roseville, Lindfield, Killara, Gordon, Pymble, Turramurra and Warrawee stations, but Council scrutiny on built form and tree retention remains heavy.

Building in Warrawee — Local Context
Warrawee Block Realities
Typical Warrawee blocks are 900–1,500m² on Class M ground (moderately reactive). For a custom home, the structural envelope is more constrained than the headline lot size suggests — once you subtract setbacks, easements, landscaped area requirements, and any tree preservation, the actual buildable area is usually 35-45% of the block. We map that early in the feasibility stage so you're designing to what's actually allowed, not what looks possible from the title plan. Foundation cost band on most Warrawee blocks: $15,000–$32,000.
Approval Timeline for Warrawee
Realistic timeline for a custom home in Warrawee: 10–15 business days for CDC if the design qualifies. 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.
What a Custom home Costs in Warrawee
Warrawee's median house price sits at $3.2M–$4.6M. That's the number that decides whether a custom home build stacks up financially. A new build at $3.2M–$4.6M+ replacement is well-supported by the local market and adds resale headroom on standard 900–1,500m² blocks. Buildana provides itemised quotes — no provisional sums, no allowances, no "as per engineering" line items.
Building to Suit Warrawee
Warrawee's R2 Low Density zoning, 900–1,500m² blocks, and 1920s–1960s (heavy heritage stock) housing stock set the design context. For a custom home, the practical implications: new builds that respond to Warrawee's streetscape sell and live better than generic catalogue homes dropped on the block. Buildana's design phase resolves all of this before you commit to construction pricing.
Why Some Warrawee Builds Stall
Builds in Warrawee stall for predictable reasons. Lodgement defects (missing BASIX, wrong drawing scale, undeclared overlays). Soil surprises on Class M 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. Ku-ring-gai 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 Warrawee
Most disputes I see with custom home clients trace back to one thing: vague contracts. In Warrawee specifically, where Ku-ring-gai 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 Ku-ring-gai Council approval as a fixed item. If we misjudge the envelope, that's our cost, not yours.
Honest take on Warrawee: the 1920s–1960s (heavy heritage stock) 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 Ku-ring-gai 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 Warrawee block and work out what the land wants — sun path, slope, views, neighbours, the R2 Low Density 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 Warrawee 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 soil, BASIX 2025, Ku-ring-gai 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.
