Custom Home North Narrabeen — Design, Approval & Build Under One Contract
Full design-and-construct service in North Narrabeen 2101: site assessment, architectural design, Northern Beaches Council approvals, engineering, construction and handover. One builder, one price.
Custom Homes Designed for North Narrabeen
A custom home in North Narrabeen is a coastal design where the ground does the talking. On the lagoon-fringe lots, coastal acid sulphate soils turn excavation into a managed process, and the direct beachfront sits inside the coastal hazard zone, so the design and siting are shaped by which part of the peninsula you are on. The 1920s to 1960s beach-house stock is steadily giving way to contemporary homes built for the setting.
Where the ground is stable sandstone back from the water, a new build has more freedom, with rock in the dig priced by test hole. Lagoon and beachfront lots need specific engineering and salt-grade specification throughout, and a well-designed upper level can claim ocean or lagoon views in a $2.6M to $5M-plus market. We confirm the soil and hazard mapping before design.
What I would check first on your North Narrabeen block: whether you are lagoon-fringe, beachfront or stable sandstone, the salt-grade spec, and the view a design would claim. 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.

The ground does the talking
On the lagoon-fringe lots, coastal acid sulphate soils turn excavation into a managed process, and the direct beachfront sits inside the coastal hazard zone.
So the design and siting are shaped by which part of the peninsula you are on, with the 1920s to 1960s beach-house stock giving way to contemporary homes.
Freedom on stable ground
Where the ground is stable sandstone back from the water, a new build has more freedom, with rock in the dig priced by test hole.
Lagoon and beachfront lots need specific engineering and salt-grade specification, and a well-designed upper level can claim views in a $2.6M to $5M-plus market.

How It Works
From First Call to Final Key
We start at the kerb. Before a single sketch, we stand on your North Narrabeen block and work out what the land wants — sun path, slope, views, neighbours, the R2 Low 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 North Narrabeen 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 Hawkesbury Sandstone soil, BASIX 2025, Northern Beaches 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.
