Granny Flat Builder in Curl Curl
Which side of Curl Curl you are on changes the granny flat conversation completely. Near the lagoon, coastal acid sulphate soils demand careful excavation and drainage design. On the ridge, Hawkesbury Sandstone means rock money. Along the beachfront, the Coastal Hazard zone adds its own controls, and the Heritage Conservation Area covers the older streets. Same suburb, four different rulebooks.
Blocks of 450 to 800m² mostly clear the SEPP minimum, and $620 to $900 a week in rent, beach proximity plus Northern Beaches Hospital staff, makes the effort worthwhile on the right lot. The wrong lot eats budget in ground conditions nobody priced.
What I would check first on a Curl Curl block: which of the four zones it sits in, the ground conditions that follow, and the siting. Those set the budget.
We build these fixed-price, licence HBL 487805C. Tell us your street and we will tell you which rulebook you are in before anyone talks money.

Four rulebooks in one suburb
Which side of Curl Curl you are on changes everything. Near the lagoon, coastal acid sulphate soils demand careful excavation and drainage. On the ridge, Hawkesbury Sandstone means rock money. Along the beachfront, the Coastal Hazard zone adds controls, and the Heritage Conservation Area covers the older streets.
Same suburb, four different rulebooks. So the first job is knowing which one your street is in, because the ground conditions follow from it.
The right lot makes it worthwhile
Blocks of 450 to 800m² mostly clear the SEPP minimum, and $620 to $900 a week in rent, off beach proximity and Northern Beaches Hospital staff, makes the effort worthwhile on the right lot.
The wrong lot eats budget in ground conditions nobody priced. Send us the street and we will tell you which rulebook you are in before anyone talks money.

How It Works
From First Call to Final Key
Most Curl Curl blocks support a granny flat — the question is where it sits, how it accesses the street, and how it shares the yard with the main house. We work that out on site, with the existing house and existing services in front of us.
⏱1-bed or 2-bed floor plan designed for your Curl Curl block — up to the NSW maximum of 60m². Layout, window placement, kitchen and bathroom positioning optimised for liveability and rental appeal.
⏱We lodge your CDC application with all required documentation — BASIX, plans, site analysis, stormwater. Private certifier approval in 10–15 business days. CC issued and you're ready to build.
⏱12-week typical timeline for a 60m² 2-bed: slab pour week 1, frame stand weeks 2–3, lock-up week 5, internal fit-out weeks 6–10, finishes and external works weeks 11–12. We provide the dated programme upfront so you can plan move-in or tenant placement.
⏱OC issued, defect-free inspection completed, keys handed over. Your granny flat is ready to occupy or lease. Well-finished 2-bed units near B-Line bus to CBD (Brookvale interchange) station are achieving $620–$900/week (beach proximity + Northern Beaches Hospital staff demand drives premium) per week.
