A custom home in Narrabeen 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.
Custom Homes Designed for Narrabeen
Beach side or lagoon side? Every custom home in Narrabeen starts with that question, because the two edges of the suburb build differently. Oceanfront lots sit in a coastal hazard zone. Lagoon-edge lots carry coastal acid sulphate soil notations that shape excavation and drainage. Between the two runs a suburb of 450 to 800m² blocks holding 1920s to 1960s beach houses and post-war brick, with medians of $2.6M to $5.5M and beyond toward the water.
Heritage Conservation Areas cross the older streets, so demolition gets confirmed early, and sandstone excavation is standard on the elevated blocks. None of this should scare you. It should just sequence you. Overlays first, geotech second, design third. The reward is a new home between an ocean beach and Sydney's biggest lagoon.
What I would check first on a Narrabeen block: whether it is beach side or lagoon side, the hazard or acid-sulphate notation that follows, and any heritage on the older streets. Those set the sequence.
We build these to standard, fixed-price, licence HBL 487805C. Tell us which street you are looking at and we will map the constraints.
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.

Beach side or lagoon side
Narrabeen builds two ways, and which one is your block decides the project. Oceanfront lots sit in a coastal hazard zone that shapes siting and construction. Lagoon-edge lots carry coastal acid sulphate soil notations that shape excavation and drainage.
So the very first question on a Narrabeen block is which edge you are on, because it changes the feasibility before the design.
Sequence, do not panic
Heritage Conservation Areas cross the older streets, so demolition gets confirmed early, and sandstone excavation is standard on the elevated blocks. None of it should scare you, it should just sequence you: overlays first, geotech second, design third.
Get that order right and the reward is a new home between an ocean beach and Sydney's biggest lagoon. Tell us the street and we will map the constraints.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. 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 Narrabeen block actually allows under R2 Low controls. Walk away with a realistic shortlist of design directions. Floor plan designed specifically for your Narrabeen block — orientation, setbacks, views, slope, and how you actually live. 450–800m² blocks allow generous layouts. Multiple options, 3D renders, and finishes palette.
⏱The Narrabeen construction phase. Fixed price, programmed, supervised. 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. You see the lodgement reference, the assessment progress, and the issued certificate at each step. Construction runs 24–40 weeks depending on size and complexity. Your project manager provides weekly updates with photos and milestone tracking. Every stage is inspected before the next begins.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. 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. You move in to a finished home, not a defects list to chase.
