Granny Flat Builder Manly — From $150K Fixed Price
Fixed-price granny flat construction in Manly 2095. 1-bed from $150K, 2-bed from $185K. CDC approval, Northern Beaches Council compliant. No hidden extras.
Manly Secondary Dwellings
Manly is one of the trickier suburbs to give a simple answer on, so I won't. A lot of it is apartments, tiny blocks and extensive Heritage Conservation Areas, and on those a granny flat is often either impossible or the wrong tool. On the larger detached heritage and contemporary blocks it can work — but rarely as a straightforward yield play at these land values.
The blocks range from 250 to 700m², and plenty of the smaller ones simply don't have the room once you count the existing house, setbacks and separation. The heritage overlays across the older streets mean most viable builds go down the DA path with a design that respects the streetscape.
Underneath is Hawkesbury Sandstone, often on a harbour or ocean fall, so rock excavation is real and can be deep — $50,000 to $150,000-plus. Beachfront blocks sit in the coastal hazard zone.
Where it stacks up, I build it to the standard Manly expects — fixed price with the heritage, coastal and rock all worked out first. Licence HBL 487805C.

Not every Manly block suits one
I'll be straight: a lot of Manly is apartments and tight heritage blocks where a granny flat can't happen or shouldn't. If you own a unit, there's no land to build on. If you're on a small heritage lot, the house and setbacks often leave nothing for a compliant second dwelling. I'd rather tell you that than take a job that won't deliver.
On the larger detached blocks — the bigger heritage homes and contemporary rebuilds — it can work, usually as guest quarters, a studio or family accommodation rather than a raw rental. At Manly land values, that's typically the point.
Heritage, harbour fall and deep rock
Most viable Manly builds go down the DA path because of the heritage overlays, with a design that defers to the streetscape. It's more process, and here it's warranted.
The sandstone often sits on a harbour or ocean fall, so rock excavation is real and can be deep — $50,000 to $150,000-plus. I get a proper geotech bore because guessing the rock in Manly is expensive. Beachfront blocks also carry the coastal hazard overlay, which I check before quoting.

How It Works
From First Call to Final Key
Most Manly 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 Manly 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 Manly Ferry to Circular Quay + B-Line bus to CBD station are achieving $620–$900/week (beach proximity + Northern Beaches Hospital staff demand drives premium) per week.
