Quick Answer

A custom home in Warriewood costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Northern Beaches Council approvals and fixed-price construction.

Building Custom Homes in Warriewood

A custom home in Warriewood is either an oceanfront replacement or a build on a master-planned release lot, and the two are very different jobs. On the original streets, Federation beach houses and post-war brick give way to contemporary homes designed for the coast, while the Warriewood Valley Release Area offers 2010s-onward R3 and R4 medium-density lots. In a market reaching $2.4M to $5M-plus on the oceanfront, the setting drives the value.

The ground sets the rules. Direct beachfront sits in the Coastal Hazard zone with specific engineering, lagoon-margin lots carry coastal acid sulphate soils that complicate excavation, and Hawkesbury Sandstone means rock is typical, priced by test dig. Salt-grade specification is standard near the water, and a well-designed level can claim ocean or valley outlook.

What I would check first on your Warriewood block: whether it is oceanfront, lagoon-margin or release-area, the hazard and soil mapping, and the salt-grade spec. Those set the home.

We build these fixed-price, licence HBL 487805C. Have us read your block before you design.

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.

How It Works

From First Call to Final Key

We come to your Warriewood site or you visit our office on The Horsley Drive in Fairfield. Either way, you leave the meeting with a clear cost band, an outline timeline, and a yes/no on whether your block supports the home you have in mind.

Our designer draws up plans matched to your Warriewood block — north-facing living, compliant setbacks, garage placement, and outdoor flow. You get floor plans, elevations, and 3D renders to review before we lock in the design.

Documentation is where bad builders cut corners and good builds stay on track. Buildana commissions the borehole, instructs the engineer, prepares BASIX, and aligns hydraulic, structural, and architectural drawings before lodgement.

CDC fast-track (10–15 business days) or DA through Northern Beaches Council (40–90 days). Warriewood is zoned R2 Low.

Slab, frame, lock-up, fit-out, external works — all under fixed-price contract. Dedicated project manager on your build, weekly progress reports, and quality inspections at every critical hold point.

OC, six-year structural warranty, two-year non-structural warranty, all manufacturer warranties on appliances and fixtures, BASIX certificate, certifier sign-offs, and maintenance schedule — all handed over in a single documentation pack. Keep it for your records and any future sale.

CDC approval pathway in 10–15 business days where eligible
Northern Beaches Council DA lodged cleanly to avoid 40–90 day RFI cycles
Design locked in 4–8 weeks with full 3D walkthrough before committal
Engineering, BASIX and documentation run in parallel — not sequential
Trade sequencing programmed before slab pour, not reactive on site
Weekly milestone updates with photographs and timeline tracking
Construction programme: 24–40 weeks slab-to-keys for standard builds
Defect-free handover — not a punch-list you chase after move-in
