Building Granny Flats in Cremorne Point
I'll be honest about a granny flat in Cremorne Point: it's rarely viable, and you deserve to hear that before spending on plans. This is a premium harbourside peninsula of Federation mansions, inter-war flats and harbourside apartments on 350 to 700m² blocks — much of it strata, most of it heritage-controlled, and a lot of it with substantial fall straight to the water.
Where a secondary dwelling can work is one of the rarer freestanding estate lots at the larger end, held outside strata, with room in the grounds and a heritage strategy that respects the streetscape — a guest studio or multigenerational wing, done via a full DA, not the fast CDC path.
The ground is sandstone-dominant with H to E on the fall, so engineered slabs and substantial retaining are standard, and rock excavation is usually part of the job. This is serious, architect-led work when it happens at all.
We build to the standard the address demands, fixed-price, licence HBL 487805C. I'll tell you honestly whether it stacks up first.
Buildana manages the full granny flat process in Cremorne Point — from site assessment and CDC fast-track approval through to fixed-price construction and handover. We build studio, 1-bedroom, and 2-bedroom designs up to the NSW maximum of 60m².

Rarely viable — here's why
Cremorne Point is Federation mansions, inter-war flats and apartments on 350 to 700m² blocks — much of it strata, most of it heritage-controlled, a lot with substantial harbour fall.
So a detached secondary dwelling is only occasionally on the cards. I'll tell you honestly before you spend on plans.
Where it can work
A rarer freestanding estate lot at the larger end, held outside strata, with room in the grounds, can take a guest studio or multigenerational wing via a full DA.
The sandstone ground with H to E fall means engineered slabs, substantial retaining and rock excavation — serious, architect-led work.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Site visit to your Cremorne Point block to check feasibility — lot dimensions, sewer and stormwater locations, driveway access, and North Sydney Council's setback and landscape requirements. Written feasibility report within 3 business days. Design pulls from a library of plans we've refined over years of Cremorne Point-area builds, then adapts to your specific block constraints. Faster than starting from scratch, better than buying a stock plan that doesn't suit the site.
⏱The Cremorne Point construction phase. Fixed price, programmed, supervised. Most Cremorne Point granny flats qualify for CDC — faster and simpler than DA. Buildana prepares all documentation, lodges with the certifier, and obtains the Construction Certificate. Typical turnaround: 2–3 weeks. Construction in your back yard means coordinating site access, material delivery, and trade movement around the existing house. Buildana plans the build to keep main-house disruption to a few hours per week, not constant noise and dust.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspection, Occupation Certificate, keys, and maintenance guide. Ready for tenants or family. Rental potential: $700–$950/week per week.
