A duplex in North Curl Curl depends on where the block sits, because the beachfront carries a Coastal Hazard zone and the village is heritage, while inland lots clear the Northern Beaches 600m2 minimum. This oceanfront suburb runs Federation beach houses, post-war brick and contemporary on 450 to 800m2 blocks, and direct beachfront is heavily constrained while the older streets carry a Heritage Conservation Area. On an inland lot off both a Torrens-title duplex can work.
The ground is Hawkesbury Sandstone with rock excavation typical, so a duplex spreads that across two footprints, and coastal salt-grade specs apply near the beach. On a qualifying inland non-heritage lot a side-by-side works cleanly. Where older homes carry fibro a licensed asbestos strip-out comes first.
What I would check first on your North Curl Curl block: whether it sits in the Coastal Hazard zone or the heritage streets, whether it clears the 600m2 minimum, and the rock. That decides the direction.
We build these fixed-price, licence HBL 487805C. Send me the address and I will tell you honestly what the block suits.

Beachfront and heritage constraints
This oceanfront suburb runs beach houses, post-war brick and contemporary on 450 to 800m2 blocks, with a Coastal Hazard zone on the beachfront.
The older streets carry a Heritage Conservation Area, while inland lots off both may clear the Northern Beaches 600m2 minimum.
Rock and salt
The Hawkesbury Sandstone means rock excavation typical, spread across both dwellings on a duplex.
Coastal salt-grade specs apply near the beach, with older fibro stripped under licence first.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your North Curl Curl block — lot size (typical 450–800m²), width, R2 Low zoning, setbacks, FSR, landscaped area requirements under Northern Beaches Council's LEP and DCP. Minimum lot for duplex: 600m² (Manly/Pittwater legacy R2) / 700m² (Warringah legacy R2) / varies by precinct under Northern Beaches LEP. You'll know viability before spending on design. Design phase covers unit layout, access, parking, private open space, and waste management for dual occupancy on your North Curl Curl site. You approve final plans before we move to lodgement.
⏱The North Curl Curl construction phase. Fixed price, programmed, supervised. Duplex approvals get scrutinised harder than single dwellings — neighbour notification, overshadowing, privacy, traffic, waste. Our SEE addresses each on the front foot rather than reactively. Cleaner submission, fewer conditions, faster CC. Fixed-price construction of both dwellings from slab to keys. Class Hawkesbury Sandstone engineered footings, frame, lock-up, internal fit-out, and external works. Weekly progress reports.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Subdivision registration starts in parallel with final fitout so titles issue close to handover, not 6 months after. Buildana coordinates the surveyor and Northern Beaches Council clearance — important if you're planning to sell one side immediately to fund the next move.
