A custom home in Bayview 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.
Bayview Custom Home Construction
A custom home in Bayview is a Pittwater-fall build where the site controls are as important as the design. The blocks run 800 to 2,000m2 with substantial sandstone fall to the water, and at a $3.5M to $10M plus market for waterfront, the land and the outlook justify a home engineered to step down to Pittwater. This is premium waterfront country and it builds accordingly.
This is Hawkesbury Sandstone with deep rock excavation, so the substructure is engineered and priced honestly from the outset, and most bushland-fringe lots carry a BAL rating from 19 up to Flame Zone that drives the spec. A Foreshore Building Line governs direct waterfront, and parts of the western bushland edge sit under the Sydney Drinking Water Catchment overlay, so the site assessment comes before the drawing. A level-changing design captures the Pittwater view the suburb is built on.
What I would check first on your Bayview block: the rock and substructure, the BAL rating, and the Foreshore Building Line or catchment overlay. Those set the home.
We build these fixed-price, licence HBL 487805C. Show us your fall and outlook and we will design to it.
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.

Built to Pittwater
The blocks run 800 to 2,000m2 with substantial sandstone fall to the water, so a level-changing design steps down to the outlook.
At a $3.5M to $10M plus waterfront market, the land and the view justify a considered, engineering-led home.
Site controls come first
This is Hawkesbury Sandstone with deep rock, so the substructure is engineered and priced honestly, and most fringe lots carry a BAL rating up to Flame Zone.
A Foreshore Building Line governs direct waterfront and parts of the western edge sit under the drinking-water catchment overlay, so site assessment precedes design.

How It Works
From First Call to Final Key
First meeting is about getting the brief right — number of bedrooms, lifestyle priorities, future-proofing, budget envelope, and what you'd hate to compromise on. We pair that with what your Bayview block actually allows under R2 Low controls.
⏱Floor plan designed specifically for your Bayview block — orientation, setbacks, views, slope, and how you actually live. 800–2,000m² blocks allow generous layouts.
⏱We prepare everything needed for approval — engineering drawings sized for Class Hawkesbury Sandstone ground conditions, BASIX certificate, geotech report, survey, and stormwater plan. All documentation handled in-house.
⏱Lodgement, RFI responses, condition negotiation, and CC issue — all managed in-house. Northern Beaches Council has typical processing windows we plan around so the build start date isn't a moving target.
⏱Construction runs 24–40 weeks depending on size and complexity. Your project manager provides weekly updates with photos and milestone tracking.
⏱Handover is a sign-off process, not a key drop. We walk every room with you, mark anything below standard, complete those items before settling, then issue OC, warranty, and documentation.
