Granny Flat Builder The Spit — From $150K Fixed Price

The Spit Granny Flat Construction — Fixed Price
A granny flat at The Spit is a premium, family-driven build shaped by rock and heritage. On 600 to 1,500m² blocks worth $4.5M to $10M at the southern end of the Spit Bridge, a secondary dwelling is guest accommodation, a studio or multigenerational space — the lot clears the 450m² Housing SEPP threshold comfortably, so size isn't the question.
The site is. Sandstone-dominant ground with deep rock excavation typical, and substantial fall to Middle Harbour, means engineered slabs, substantial retaining and serious excavation — scoped off a real geotech before design. Heritage Conservation Areas over most older streets add a full DA to the path.
So I scope the rock and the heritage first. On these blocks the build is discreet, beautifully made and engineered for the fall, worthy of the harbour outlook.
We build to that standard, fixed-price, licence HBL 487805C.
Buildana manages the full granny flat process in The Spit — 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.

Premium, family-driven
On 600 to 1,500m² blocks worth $4.5M to $10M, a secondary dwelling at The Spit is guest accommodation, a studio or multigenerational space — the lot clears the 450m² Housing SEPP threshold comfortably.
The Middle Harbour outlook carries the premium, so the dwelling is built to suit the address.
Deep rock and heritage
Sandstone ground with deep rock excavation typical, and substantial harbour fall, means engineered slabs, retaining and serious excavation off a real geotech.
Heritage Conservation Areas over most older streets add a full DA to the path — scoped first.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Site visit to your The Spit block to check feasibility — lot dimensions, sewer and stormwater locations, driveway access, and Mosman 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 The Spit-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 The Spit construction phase. Fixed price, programmed, supervised. Most The Spit 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: $800–$1,200/week per week.
